Reverse Osmosis Membrane

What would cause a pressure drop within the feedline to a large-scale reverse osmosis system?

I'm interested in the troubleshooting procedure for an increase in headloss within the piping prior to RO membranes.

Whether the pressure loss is gradual or sudden would have a lot of bearing on where to look for the problem.
The usual suspects - a partially closed valve; a deffective valve; gradual buildup of scale deposits.
Is the discharge pressure of the pump the same ?
What else has changed ?

How do reverse osmosis membranes work and what affects quality and production?

Osmosis is the flow from a high concentration of water to a low concentration of water. To help understand the flow of water imagine a sealed filled water balloon with a hole in it what happens to the water inside? The water quickly leaves balloon because of the concentration of water inside the balloon is higher than outside which makes the water wants to equalize the concentration of water.

Reverse osmosis is quite the opposite. The flow of water is from a low concentration to a high concentration. Imagine an empty balloon if you’re filling the water balloon with a hose then you are using the water pressure and forcing water against its natural equalization tendencies.

A reverse osmosis (ro) membrane is simply a thin semi-permeable layer that separates two solutions. A ro membrane is a type of physical separation that is capable of separating molecules down to 1/10,000 micron. Since the size of the pores on the membrane is so small, it requires pressure to force water through. Most molecules are too large to pass through a reverse osmosis membrane but small enough for some salts, sugars and water molecules to pass through. Rejection rates of ro membranes average around 96-98% under ideal conditions (250 ppm softened tapwater, 77 °F (25 °C), 50 psig (3.4 bar), and 15% recovery).

TDS levels, temperature, pressure and recovery rates are all things that affect the product water quality of reverse osmosis membrane.

Effect of Pressure

Feed water pressure affects both the product water production and the rejection rates of RO membranes. The increase of feed water pressure directly increases the water production.

Rejection rates also increase when pressure is increased but will plateau.

Effect of Temperature

Temperature has a direct linear effect to production rates. As temperature increase, water production increases almost linearly because of the higher diffusion rates of water through the membrane. Rejection rates are actually lowered when temperature rises. This is due to a higher diffusion rate of salt across the membrane.

Effect of Salt Concentration or TDS

TDS inversely affects the pressure required for reverse osmosis which in turn affects the production rates. If feed water was constant and TDS increases then the production rate decreases because of the osmotic pressure difference.

Osmotic pressure is the pressure and potential energy required to force water to move against its natural direction across a semi-permeable membrane. Every 100 ppm (parts per million) in TDS equals 1 psi (pounds per square inch). The higher the TDS, the more pressure required to force through the membrane.

Effect of Recovery Rates

Recovery rate refers to the amount of product water being produced which is controlled by the flow restriction on the waste line. Most reverse osmosis systems are sized with a sized flow restrictor will have a product to waste ratio of 1 to 4 which is a recovery rate of 25% this is made purposefully as a sales point to produce more product water but lower the rejection rate. For example, the proper size for a 50 GPD membrane is a 15% recovery rate or a 1 to 6.7 ratio. Lowering the recovery rates will increase the rejection rate and improve the quality of water. Raising the recovery rates will cause the quality of the product water to decrease and will affect the required driving pressure needed for reverse osmosis to take effect.

Reverse Osmosis Membrane

Commercial Water Filters

A new concern today that some water filter systems have not addressed is chloramines, a by-product of 9/11 when authorities began calling for more chlorine in water supplies to counter bio-terrorism. This additive is fast becoming a super-toxin threat in our water. Created by the combination of chlorine and ammonia, this powerful compound being added to most municipal water supplies is not only a serious threat to our health, but if not filtered out using a reverse osmosis water filter system prior to reaching interior plumbing, could cause an unrivaled corrosive capacity that homeowners have not had to contend with before.

Reverse Osmosis Water Filter Systems use pressurization through Reverse Osmosis membranes in home and commercial water filter systems to produce filtered water as essentially pure as distilled water. Reverse Osmosis filter systems provide the purest drinking water and the safest non-mineralized water for use in machinery and household and kitchen appliances. Reverse osmosis water filter systems can lengthen the life of kitchen appliances by filtering out chemicals that can clog or corrode met and plastic pipes and tubing downstream from the RO system.

Filtered water leaving most municipal water supply systems still contains some dissolved particles and other substances that can enter homes and businesses if not blocked by water filter systems. This became apparent recently when the evening news carried a report that one odd tap water sample tested positive for pharmaceutical and hormone residues. This sparked similar testing and also similar results in municipal water authorities across the country. When confused municipal water executives were then questioned as to how something like this could possibly have happened, it turned out it was quite simple. No one even expected that such a problem could have existed in municipal water, so routine tests being done on water supplies did not include a test to determine such residues.

Chloramines can slowly destroy water pipes in the basement and walls, and metal and plastic seals and tubing in kitchen appliances from ice maker water filters to the water filters in espresso machines. The dangers chloramines present may change the entire face of water filtration technology and purification systems in the future.

High chlorine levels after 9/11 manifested in residents complaining of irritated skin, hair, and lungs. Investigations unearthed bacteria forming bioshields in piping and resisting chlorine’s purification power, and brought out the fact that chlorine in water produces carcinogenic trihalomethanes (THMs). The only answer seemed to be combining chlorine and ammonia, creating chloramines. This allowed the use of much less chlorine and lowered the levels of THMs while still provided plenty of muscle against bacteria and bioterrorism threats.

Multi-stage Reverse Osmosis systems like the Watts Pure Water Filter System can filter out such dangerous corrosives and many other water-borne chemicals from reaching the drinking water of homes and business, protecting costly appliances like coffee machines. The Watts Pure Water Filter system can include a 5-micron sediment filter to trap sand and rust, a 5-micron carbon filter to catch chlorine and other substances that can affect taste, a 5-micron carbon pre-filter to block chlorine from entering the RO system, and the RO Membrane which completely removes dissolved solids such as sodium, perchlorate, chromium, arsenic, copper, and lead. The Watts Pure Water Filter system also removes infectious cysts such as Giardia and Cryptosporidium.

A Reverse Osmosis GAC final filter is a final polishing filter used as the water leaves the storage tank on its way to the faucet. Pure Water filter systems are Reverse Osmosis filtering systems that provide pure, demineralized water to a home or business without the concern of corrosive chemicals, heavy metals, or pharmaceutical residues getting inside. Protect your home and protect yourself with the safest form of water filtration available, a Watts Reverse Osmosis Water Filter System.

Looking out for buying a water purifier? I am sure you must have heard about reverse osmosis water units. Read on to find out about the most basic component of these RO systems - the reverse osmosis membrane.

A reverse osmosis system is essentially made up of a thin, semi permeable, porous membrane. This reverse osmosis membrane has ultra-fine pores on its surface, the size of which basically determines what all things are going to be filtered.

When water is forced to pass through this membrane, it being smaller in molecular size, passes through the membrane and other contaminants being larger in size are blocked and hence separated out from the water.

This basically makes this membrane the most important part of a RO based unit. Broadly speaking, the reverse osmosis membrane is available in two flavors.

- Cellulose Triacetate Membrane (CTA): These membranes are extremely hydrophilic and are ideal for removing antibodies from the water. The problem with these membranes is that they are totally non-protein binding, so they remove proteins also from the water. Moreover, this membrane needs to be disinfected regularly so as to keep bacterial growth in control.

- FTC membranes: These membranes being inorganic in nature are not susceptible to bacterial growth. So they do not need disinfection. But they are more expensive as compared to the CTA ones. The problem with these membranes is that they are prone to be easily damaged by chlorine- a common contaminant in water.

These RO membranes are ultra thin and very sensitive. Thus are vulnerable to damage. But detecting the damaged membrane is a difficult task. If this goes undetected, the microscopic wastes will easily pass through the membrane and hence will not be separated out from the water.

One critical problem with this membrane is that the size of its pore is smaller than that of various naturally occurring minerals. This results into blocking of these minerals and so they are removed from the filtered water. This is known as de-mineralization.

Consuming such de-mineralized water is not recommended. The minerals which are removed by a reverse osmosis membrane are required for the basic functioning of the body. These minerals are calcium, magnesium, sodium, iron etc.

Drinking water is the best source to ensure daily intake of these minerals. Water lacking in these minerals can lead to deficiencies and other health problems.

Multi-stage water purifiers are superior to RO bases units. They are capable of removing all contaminants while retaining the essential minerals at the same time. They are easy to maintain and come in large variety of sizes and colors.

Now that you know about reverse osmosis membrane and how reverse osmosis work, I hope this information will help you in deciding a home water purifier for you. Whatever you select, make a choice soon. Drinking clean water is our body's most basic and important requirement.

How difficult is it to replace an EverPure water filter?

Previous occupant of my home installed an EverPure H-54 water filter to filter the water going to the water dispenser and ice maker of the refrigerator. I've seen these filters online for $55 or so. Is this something that I can easily replace by shutting off the water and using some simple wrenches and screwdrivers? Or should I get it professionally installed?

It's actually very simple to replace. This is a copy and paste from the Everpure website.

How do I remove “used” cartridges and install new ones?

Shut off water and relieve line pressure. For heads with built-in shut-off valve, fully lift handle until it stops.

Hold head firmly. Push upward on cartridge and turn it to left 1/4 turn, until rotation stops.

Pull cartridge out of head.

Align new cartridge lug with head label. Hold head firmly. Insert new cartridge into head.

Turn cartridge to right 1/4 turn until rotation stops.

Turn on water supply. For heads with built-in valve, lower handle.
Note: For head with revolving ring, make sure the valve handle locks firmly into the ring notch.

Flush cartridge by running water through filtered faucet for three minutes to flush cartridge and purge it of air.

anyone tried rear sea monkeys without using the water purifier #1?

i found some information in www.sea-monkeys.com bout the water purifier. it actually helps the sea monkeys to hatch. but, after i poured the water purifier #1 into the tank, i accidentally contaminate the tank with oil so i disposed the water n refill it with RO (reverse osmosis) water. if i go ahead to add in the instant eggs #2, i wonder will they hatch? anyone ever tried it? i hope someone tried it n is successful. i really hope my sea monkeys won't die. thx for yr help

no it wont work. the "purifier" actually contains salt and a few eggs. remember, seamonkeys are actually brine shrimp, as such, they need salt water to hatch and survive.
about the bleach thing, the bleach solution is for dissolving the egg casing. this is used by people who use seamonkeys(brineshrimp) to feed their fishes. this eliminates the need to separate the eggcasings from the brineshrimp.
getting back to your sea monkeys, to hatch them you'll have to make your own brine solution since you disposed of the "purifier" try 3 tbsp of salt per liter of water. the second package,the egg package, contains some eggs too but you'll have to wait another 24 hours for those to hatch. also, i dont think you need to use RO water

Osmosis Water Purifier

Recently I moved to Atlanta in Georgia. We used to get drinking water from a nearby well. But the taste was bad and we started purchasing bottled water. But soon we were compelled to search for an affordable alternative as it was quite expensive. One of my colleague suggested me to install reverse osmosis water filtration system in the home. After performing some research online I decided to try it. And I am glad that I did!

I couldn't be more pleased with the results. After the installation of reverse osmosis water filter system my wife wasn't able to notice that it was ever well water. And there are reasons for such an observation... No odor, no smell and great taste. The water purification system worked absolutely amazingly... Filtering out contaminants that can harm our small kids.

People often think water purifier as a luxury instead of a necessity. You can live without food for several days but not water. Contaminated water is the major source of all the health related disease in the world. Being a caring husband and father of two kids I well understand the dangers of contaminated water - and wants my family to lead a healthy lifestyle. For safe drinking water I believe in reverse osmosis water purifier. And I believe that after reading this article you will too consider about it. So please read on...

Reverse osmosis commonly refers to the water purification technology that is used in households and industrial establishments to produce pure, healthy, great tasting water.

You just need to replace the filter after certain period of time. The time period depends upon the amount of use and how much your unit is building contaminants.

Reverse osmosis unit has two different filters: pre-filter and semi-permeable osmosis membrane. The pre-filtration process is used to remove the larger elements and sediments from the fluid and is often used with a carbon-based filter. After the pre-filtration stage the liquid is then prepared to be moved on to semi-permeable osmosis membrane. At this stage the liquid is permitted to pass through it under pressure while the membrane traps the pollutants and bacteria.

With several options on how to filter and purify both at home and offices there is no question reverse osmosis water filtration system is a highly effective method. Explore your options and ascertain whether reverse osmosis water filtration will satisfy your needs.

Faucet Water Filter
what is the best faucet filter for well water?

I am thinking about purchasing a filter for my kitchen sink, but we have well water and I am wondering what would be the best filter for me to purchase? thanks in advance :]

There are so many things to consider.

If you are just concerned with taste and odor, purchase a carbon impregnated filter with a 25 micron particulate built in. This is a typical filter you can get at Sears and such. It it recommended to change at 6 months to a year. I would stay with at least 6 month because after the carbon breaks down in the filter, it becomes the BEST place for bacterial growth and contanimants.

You probably won't find a filter that is anything other than carbon or particulate filtration for just a faucet attachment.

If you really want a better water, buy or rent a reverse osmosis machine. This will take up to 98% of the total dissolved solids out of the water. Within the RO machine is a particulate filter (25micron), carbon absorbtion filter and a reverse osmosis membrane. It is costly to replace the filters though. It is almost best to rent one for about 25 bucks a month. Make sure they take care of EVERYTHING.

There are parameters in which you cannot use an RO. If your well water is extremely hard 20 grains per gallon of calcium and magnesium, the filter won't last very long at all. The other problem would be if it is high in iron content. This would clog quickly.

If you have H2S, hydrogen sulfide (rotten egg odor) no filter will take that out. You have to chlorinate and remove the equestered solids.

You typically can take a water sample to Culligan, Rainsoft or a local water purification company and they can test for:

Hardness
Iron
Chlorine &
SDI (silt density index)

That would be your best start. Otherwise, if you just want to slap a filter on your faucet, 25 micron or less with a carbon absorption filter built in. Keep it changed though!!

Hope this helps, probably too much info, but I was in the business for about 20 years.
