Reverse Osmosis and Deionized Water Filtration

!9#: Reverse Osmosis and Deionized Water Filtration

Let's face it if you are in a business needing de-ionized water or reverse osmosis water you are always concerned about the quality of your water. I know as a mobile detailing business that when we have ultra clean water in our tanks we are a happy camper. We know it will make your job so much easier. We also like the idea and concept of spot free water. Have you ever considered how Reverse Osmosis really works? Let me describe the process from my industries perspective.

In R.O. water pressure forces water through a fine membrane that filters out between 85-95% of the dissolved solids in the water. Water lacking these solids won't water spot a car. It's important to have soft water filter inline the R.O. system prior to R.O. Some systems have a water softener/carbon filter/R.O. system in that order. This saves life on the R.O. membranes. R.O. units are measured in gallons per day (GPD) because there flow is relatively slow. Usually they run twenty-four hours a day and the water is put into a storage tank to be used later. Small R.O. units that cost between ,500 and ,000 put out 4 gpm. To go to 10 gpm, the speed at which you'd want to fill your tank, the cost of those units starts at ,000.

Car washes need units that make between 500 to 1000 gallons a day for the rinse cyles. A small unit will work because 4 GPM (gallons per minute) X 60 minutes is 240 gallons. So, in four hours at night when the car wash isn't being used, they will have one thousand plus gallons. The only problem for them is that a thousand gallon tank is five feet wide and eight feet tall.

An R.O. machine works best when it's running clean water through it. Otherwise, the membranes let nature take over. Then you have not reverse osmosis but osmosis. It's better to have a small machine running twenty-four hours a day than a big machine running two hours and then shutting off. R.O. membranes should have a constant positive flow through them. Some industry leaders believe twelve to thirteen hours is the maximum you should run an R.O. unit a day. They think the machine will last longer.

Silica, iron, aluminum and bacteria cause irreversible damage to membranes and that's why pre-filters are a must to keep membranes from fouling. Fouling results when particles suspended in the feed water are deposited within the R.O. unit. Fouling reduces permeate flow rate. Bacteria fouling usually doesn't cause the permeate conductivity to increase until your system is extremely plugged. Other particles may cause permeate conductivity to increase.

Most biological and particulate silica foulants can be removed with the proper chemicals. Bio-fouling is a problem. Pre-treatment may have little impact on R.O. unit fouling. Simply killing the bacteria won't work because the same number of fouling particles (living or dead) still enter the R.O. unit. The best way to handle bio-fouling is cleaning the equipment and the upstream pipes and filters. Chlorinated water will be bad and should be un-chlorinated before entering the R.O. unit. Fouling by non-living particles is handled by your pre-filters, or additional sediment filters or cartridge filters with a nominal filtration rating of five microns or less. This can be complicated stuff and you can call your franchsior for a telephone number of a fair and honest local or regional water purification consultant.

Chlorine is the most common agent to chemically attack and destroy the polyamide thin film membranes that are commonly used in car washes. Activated carbon blocks are used generally in filters upstream from R.O. units. Larger units use granulated carbon filters or other methods. Active chlorine consuming sites on the activated carbon material is depleted over time and eventually dechlorination will diminish and finally cease. This will allow chlorine to damage downstream chlorine sensitive membranes in your R.O. unit. Carbon filters must be replaced as frequently as their manufacturers specify.

Most commercial R.O. units are too small to justify installing instrumentation to determine when to clean them. Cleaning periodically can remove most scalants and foulants. If you wait too long permanent damage will be done and proper cures will not work. If you wait until you have low flow problems, the elements may be plugged significantly and chemical cleaning may be ineffective or may take many hours to get the elements back to near original performance.

If you want, you can have the R.O. dealer do periodic cleaning on a service contract. It may be worth your while. Expect to pay between to 0 per quarter. Watch for parts price gouging. Some companies are like sharks. If well taken care of, the membranes will last years. You may want to have a technician also check upstream filters. That way, if anything does go wrong, it's their responsibility and you can make them pay. Make sure your contract is tied to their lifetime warrantee. Regular Maintenance Of Reverse Osmosis Units is ultra important and you should change your prefilters often. Water softeners every month, carbon filters quarterly. Be sure to check the pressures weekly and membranes will need changing every so often too. Think on this.

Deluxe Filter System

This 2-step filtration system prevents two of the most common culprits of micro-marring. You wouldn't rub sand on your paint finish; why would you wash your vehicle in sediment and hard water? In short, most of us need a two-part filtration system to ensure that the water coming out of the garden hose is truly clean. The Deluxe Filter System is a comprehensive two-step, in-line filter system that both removes sediment and softens the water. This one package is all you need to ensure you're washing your vehicle in clean, soft water. The Deluxe Filter System is a practical solution to hard water and sediment. The entire system can be attached to your hose and removed as needed. If you prefer to leave it in place, mount the two clear filters to the wall by the spigot. We recommend attaching a Y-valve to the spigot so the filter system can remain connected when not in use. Remember, if you're washing your vehicle with unfiltered water, you could unknowingly be pouring hard water scale or sediment on the paint finish. The Deluxe Filter System eliminates both culprits so the water that cleans your vehicle is truly clean.

Hard Water Treatment Methods

!9# Hard Water Treatment Methods

[if ]

[endif]

Hard water treatment methods are grouped into four categories depending on how they work. They all reduce, inhibit or eliminate limescale and each method has its own advantages and disadvantages. Below is a synopsis of how each of the four categories work, what they do, how they do it, and their advantages and disadvantages.

1) Physical Water Conditioners

Physical Water Conditioners, so called because they physically alter the properties of hard water to reduce or eliminate limescale formation, come in three different types - electronic, electrolytic and magnetic.

1a) Electronic water conditioners, also know as electronic descalers or limescale inhibitors, generally comprise of a small box of electronics and one or more coils wrapped around the pipework.

What they do: Electronic conditioners work by transmitting an audio frequency or radio frequency signal into the water via induction coils wrapped around the pipework. This inhibits the build up of limescale inside water pipes and through time, reduces existing scale. A softer scale may still form on shower heads, taps and other surfaces, but is much easier to clean.

Advantages: Electronic descalers are relatively cheap in comparison with other hard water treatment methods and offer a cost effective solution to limescale problems. No plumbing is required, making them very easy to install. And because nothing is removed or added to the water, healthy minerals are retained and the water remains safe to drink.

Disadvantages: Although sometimes not as effective as other treatment methods, most manufacturers offer a full money back guarantee if the device does not work as well as expected.

1b) Electrolytic water conditioners are inline devices that need to be plumbed into the water system. They can be bought with 15mm, 22mm, or 28mm end connectors to suit the pipework.

What they do: Inside an electrolytic conditioner are two dissimilar metals, normally copper and zinc, which act as a cathode and an anode. The electrolytic current that flows from the cathode to the anode causes small quantities of metal ions to dissolve into the water. The metal ions then disrupt the positively charged scale forming particles so that they don't clump together and form scale.

Advantages: Like electronic descalers, electrolytic scale inhibitors are relatively cheap to buy. They do not need an electric power supply and so annual running costs are zero. They provide whole house protection against limescale problems and treated water is safe to drink.

Disadvantages: Electrolytic water conditioners need to be periodically replaced to maintain the full level of protection and, unlike electronic conditioners, they need to be plumbed into the pipework, adding to the initial cost.

1c) Magnet water conditioners come in two forms. They either clamp onto the outside of the pipework or are fitted inline with the pipework in the same way as electrolytic softeners.

What they do: Magnetic conditioners work in a similar way to electronic conditioners, but use a magnetic field rather than an electric field to alter the characteristics of the scale producing minerals in the water. Scale particles in the treated water lose their ability to adhere to one another and to pipes, boilers and other internal surfaces.

Advantages: Magnetic conditioners are fairly popular due to their relatively low cost. The clamping type is easy to fit and normally just needs tightening onto the pipework with a spanner. They do not need any electrical power and so running costs are zero.

Disadvantages: Magnetic conditioners are generally not suitable for whole house protection, only single appliances. Some magnetic conditioners need to be plumbed into the pipework and they all have to be replaced periodically to maintain full performance.

2) Chemical Water Conditioners

Chemical water conditioners fall into two categories, packaged softeners and dosing systems. Packaged softeners can be further split into precipitating and non-precipitating types. The principal use of packaged softeners is to soften water for washing clothes

2a) Precipitating packaged softeners include washing soda and borax. Although borax has a number of uses around the home, the main purpose of packaged softeners is for washing clothes and as such they are not suitable for whole house water softening and treated water is not fit to drink.

What they do: Precipitating softeners soften the water by combining with calcium and magnesium ions found in hard water. This causes the mineral ions to precipitate out, so that they don't interfere with the washing process.

Advantages: Cheap, easy to use softener that, in addition to softening, also cleans and deodorises. Adding borax or washing soda to the wash, will also prevent limescale build-up in the washing machine.

Disadvantages: Precipitating softeners make the water cloudy and can cling to materials in the wash. They also increase the alkalinity of the water, which can damage skin and some fabrics.

2b) Non-precipitating softeners include products such as calgon and more commonly used than precipitating softeners. Like all packaged softeners, they are only intended for use in the laundry.

What they do: They work by using phosphates, which react with the calcium and magnesium ions in hard water and holds them in solution.

Advantages: As the name suggests, non-precipitating softeners do not form a precipitate and so the water remains clear. They do not increase the alkalinity of the water and so they're safe to use with all fabrics.

Disadvantages: Generally more expensive than precipitating softeners and not so eco friendly because of their high phosphate content.

2c) Phosphate dosing systems comprise of a cartridge of phosphate held in a container that is fitted to the plumbing system. Water passing through the cartridge is dosed with small quantities of phosphate which softens the water.

What they do: Like non-precipitating softeners, they work by adding phosphates to the water. However, in dosing systems, food grade polyphosphates are used. The polyphosphates act as a sequester to stop the hardness minerals in hard water from precipitating out.

Advantages: Dosing systems typically cost in the region of £60 to buy, plus installation costs. Although generally only used for single appliance protection, they can provide whole house treatment.

Disadvantages: Most people prefer not to have phosphates in their drinking water, even if they are food grade safe. Replacement cartridges incur additional annual running costs of between £30 and £60.

3) Mechanical Water Softeners

Mechanical Water Softeners, or ion exchange softeners as they are also know, are true water softeners. Physical and chemical conditioners, although sometimes referred to as 'softeners', do not remove hardness minerals from the water; they merely prevent them from precipitating out or from sticking to surfaces. The only true way to soften hard water is to remove the calcium and magnesium minerals that make it hard. Only ion exchange softeners, and some filter treatment methods, do this.

What they do: Ion exchange softeners work by swapping negative hardness ions in hard water with positive sodium atoms in a resin contained within the softener. Periodically, the resin needs to be regenerated to remove the build up of hardness minerals. This is done by flushing the resin with brine. During the regeneration process, household water is diverted around the softener and so only hard water is available. This is normally set to occur during the night. Alternatively, two resin tanks can be used, with one regenerating while the other is in service.

Advantages: Ion exchange softeners offer all the advantages of truly soft water for the whole house.

Disadvantages: The main drawbacks with ion exchange softeners are that they're expensive to buy, costly to run and can take up quite a bit of room (normally on the kitchen). A further drawback is that treated water contains sodium (salt). That said, they produce truly soft water and issues with sodium in the water can be resolved by leaving one outlet in the house untreated.

4) Water Filters

Water filters come in many shapes and guises from stand-alone jugs to fully integrated reverse osmosis units. The three most common types found in UK homes that will remove calcium and magnesium from hard water are carbon resin filters, reverse osmosis units and water distillers. There are many other types of filter available, but they do not produce soft water.

Since filtered water is normally only available from a single outlet, water filters do not alleviate hard water problems throughout the rest of the home. Limescale deposits will still exist through the plumbing and heating system and on taps, showerheads and other surfaces.

4a) Carbon resin filters are normally used in conjunction with activated carbon filters. The carbon resin removes hardness minerals from the water and the activate carbon filter then filters out chemicals.

What they do: Carbon resin filters use an ion exchange resin to remove hardness minerals from the water in a similar manner to mechanical water softeners. An activated carbon filter then removes chlorine and other chemicals to improve the taste and eliminate odours.

Advantages: Pleasant tasting, cheap, chlorine free, soft water.

Disadvantages: Unlike mechanical water softeners, the ion exchange resin is not regenerated and builds up contaminants until it needs to be replaced. The charcoal filter also needs periodic replacement and like all filter systems, they do not offer a practical solution to limescale problems elsewhere in the house.

4b) Reverse osmosis systems are perhaps the most popular type of filter for household water treatment. Whilst RO systems will remove calcium and magnesium ions from hard water, they are not normally installed purely for this purpose. Many homes with soft water have RO systems. Most home owners buy reverse osmosis systems to obtain cleaner, purer, water than is normally available from their water supplier.

What they do: Reverse osmosis filters work by forcing water through a semi-permeable membrane which filters out impurities. The membrane has microscopic holes through which water molecules can pass, but larger particles and molecules (like the hardness minerals) are blocked.

Advantages: In addition to effectively removing most contaminants, RO treated water tastes better, enhances the flavour of drinks like coffee, tea and fruit squashes. And in hard water areas, household appliances such as steam irons, coffee makers and kettles, will not suffer from the normal scaling.

Disadvantages: The main drawback with reverse osmosis units is that they use lots of water. Typical RO filter units purify only ten percent of the water that enters the system; the rest is piped to waste. This makes them unsuitable for whole house water treatment. Additionally, filter cartridges and the RO membrane require periodic cleaning / replacement (sometimes by a professional). Hard water also reduces the life of the RO membrane. With filter replacements typically costing between £150 and £700, they can also be expensive to maintain.

4c) Water distillers produce the purest water possible. Appliance for the home look like large kettles, while larger under-counter units are available for commercial premises and dental surgeries.

What they do: Distillers work by boiling water into steam, which then condenses back into water and is collected in a storage container. Impurities in the water are not converted into steam and so only pure water condenses into the storage container. Contaminants are left behind in the boiling chamber, which can then be cleaned with special crystals.

Advantages: Distillers offer the purest water money can buy. They have all the benefits of reverse osmosis filters plus a few others. The water they produce is purer than bottled water, always on tap and there are no heave bottles to carry back from the supermarket.

Disadvantages: Distillation is not practical or economically viable for whole house water treatment, so limescale will still build up in pipes, boilers and heat exchangers as well as on taps, shower heads and other surfaces.

Cleaning bathrooms is not the best chore any homemaker likes doing. However no matter how much you may despise the chore, it has to be cleaned at least once a week, or more if you have a large family.
Basically, bathrooms have materials that are easy to clean. Its tiles and porcelain surfaces are usually stain resistant and don't allow any build up of dirt and scum on them.

To make the chore of cleaning bathrooms easy, make sure everyone rinses the tub or shower stall immediately after using it. They just have to make it a habit to spray water on all interior surfaces, swish some soap around the tub using a damp sponge and then give a final rinse. This way the accumulation of scum on the bath is reduced to a minimum.

Tips for cleaning bathtubs

Bathtubs in bathrooms are made from various materials, where porcelain is the most widely used material. Then there are acrylic and fiberglass tubs that are lighter and easier to install than their porcelain counterparts. This is the preferred option when remodeling and in new constructions.

Clean porcelain tubs using some nonabrasive powder or liquid cleanser and a damp sponge. Stubborn soils can be removed using a synthetic scouring pad and then rinsed well.

In case of fiberglass tubs, be careful whilst scrubbing the bathtub to avoid scratches on its surface. Use commercial fiberglass cleaning product or some nonabrasive liquid cleaner with a damp sponge and then rinse with water.

Use rubber gloves for protection

Rust stains in bathtubs are best removed using commercial rust removers. However, make sure you use rubber gloves when you use them for protection from the acid in these cleaning products.

Always remember to remove hair from the drain traps before cleaning bathtubs in bathrooms, to prevent clogging of drains. The rind that forms on the tub can be cleaned using a nylon net ball or pad. If the stain is a stubborn one, let a paste of cream of tartar and hydrogen peroxide dry on it and then wipe it off when it dries.

The discoloration of yellowed bathtubs can be removed using a solution of salt and turpentine and then rinsing well. However, make sure you wear rubber gloves when you do this too.

Care of your shower stall

If you have a shower stall in your bathrooms, you can prevent mildew from forming on it by wiping the shower walls with a towel every time after you shower. Leaving the shower door ajar lets air circulate and discourage mildew growth.

A solution of white vinegar and water is great for removing hard water deposits on shower enclosures. Cleaning glass shower doors with a sponge dipped in white vinegar gives the door a sparkle. The scum in shower doors can be loosened using a solution of a cup of liquid fabric softener and a quart of warm water.

Mineral deposits in shower heads can be cleaned by taking apart the head and soaking it in vinegar. The deposits then have to be loosened using an old toothbrush whilst holes can be cleaned using a toothpick, ice pick or wire.
With all these tips, you find it easy to maintain a sparkling bathtub and shower stall in your bathrooms.

The Victorian homes had a personal care service ranging from one to no less than forty or more, depending on the size of the house or land and the needs of the family.

While wealthy families had the money to set as many employees as they wanted, it was also the middle class to raise enough extra money to hire at least one servant. After the task was so important to the social image of the Victorian house that almost 13% of womenEngland and Wales as a domestic help during the 19 Century employs.

No matter how busy servant in the house, most families followed a logical progression that setting is designed to ensure that the tasks of the house had as many as possible an appropriate person to blame for the art or to see that there was done.

Lower in the hierarchy home, and often the first to be occupied, was a waitress or cleaning lady day. The entry-level position was usuallyfilled by a teenage girl that was difficult for the overall management and cleaning. Depending on the size of the domestic workers, who might also have laundry and other tasks as well. Think Cinderella without the help of Fairy Godmother.

The next would be made to be a maid or a nanny, according to the age of children at home. The maid would help serve food and guests, update the living room, a rejection ofBeds, and adjust the hostess to help with their personal needs. Sometimes it even national services for other internal employees of high rank.

The nurse has provided all services normally provided by today's baby-sitters are available. She dressed the kids bathed and fed her, took her outside to play, and acted as a mother in many ways. In some cases, was actually a "wet nurse" to breast-feed their infants allowed in some Victorian houses.

The next in line to be takennormally cook. The cook had absolute authority over the kitchen and in homes where there was no local staff about the cleaning lady and waitress often responsible for monitoring and adjusting the home as well.

This trio of girl char, nurse or a maid and a cook was able to a wide range of services to smaller families and less wealthy Victorian. But for larger families and make the setting for the next progression of the series as a rule, amale partner. Depending on the home, usually his responsibility ranged from general maintenance to the provision of cleaning services, the landlord. He could also double as a stable keeper and drive the car too.

For families with more demand for domestic workers staff have been selected for specific positions, fill in the different families. Open positions are a maid, maid, laundress, cleaning lady (who was the servant automaticallyStaff supervisor unless he was hired a butler), groomsman driver, waiter, a cook and a variety of upper and lower living waitress, waiter, and much more. The rich have seemed a waitress for every occasion.

For families with the property (also known as country estates), has always been a number of reasons, men, gardeners, grooms and gamekeepers positions.

The hours were long and the pay was sad, but there was a sense of pride in a domestic market estimated. In fact,many servants spent a lifetime with the same employer, and often watched the children grow the new lords and ladies of the manor.
