Reverse Osmosis Drinking Water Systems

Reverse Osmosis (R/O) is a treatment process that was developed by the aerospace industry to recycle water in closed environments such as the lunar lander. This natural method of purification has been captured in your residential R/O system bringing low cost, high purity drinking water right to your kitchen.

You can be proud to serve your family, guests and pets high quality beverages, ice and food prepared with your very own sparkling clear drinking water.

Stages of reverse osmosis:

  1. During the initial filtration stage, tap water or well water (pressurized by a booster pump) is passed through a particle filter (a pre-filter) that removes silt, sediment, sand, and clay particles that might clog the R/O membrane.

  2. The water is then forced through an activated carbon filter that reduces minerals and contaminants such as chromium, mercury, copper, chloramine and pesticides. It also removes chlorine, which is important, as chlorine will shorten the life of the membrane.

  3. Water is transferred under pressure into the R/O module, allowing only clean water to pass through the small pores in the membrane. Impurities unable to pass through the membrane are left behind and flushed down the drain.

  4. Treated water is then sent to a storage tank.

  5. Treated water is passed through an activated carbon filter before use to further improve the water's taste and smell.

What Are the Benefits of Reverse Osmosis?

Reverse osmosis can remove dissolved solids, salts, minerals that cause hardness, organic chemicals and other impurities. It can improve the taste of water for people who do not like the taste of dissolved mineral solids.

Treated water will not produce scale in kettles and coffee makers. Because sodium and potassium are removed, people on a medically prescribed sodium- or potassium-restricted diet may benefit. R/O units may also remove contaminants such as chromium, mercury and nitrates.

Systems are available to suit any size application from your home right up to industrial size models large enough to serve a small community. Please feel free to inquire about the models and options available.

Units Include

Note: On units used for drinking water purposes, feed water must be microbiologically safe and potable in all respects al all times. This device is intended for water quality improvement only.

Reverse osmosis is a separation process that uses pressure to force a solvent through a membrane that retains the solute on one side and allows the pure solvent to pass to the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied. The membrane here is semipermeable, meaning it allows the passage of solvent but not of solute.

The membranes used for reverse osmosis have a dense barrier layer in the polymer matrix where most separation occurs. In most cases the membrane is designed to allow only water to pass through this dense layer while preventing the passage of solutes (such as salt ions). This process requires that a high pressure be exerted on the high concentration side of the membrane, usually 2-17 bar (30-250 psi) for fresh and brackish water, and 40-70 bar (600-1000 psi) for seawater, which has around 24 bar (350 psi) natural osmotic pressure which must be overcome.

This process is best known for its use in desalination (removing the salt from sea water to get fresh water), but has also purified naturally occurring freshwater for medical, industrial process and rinsing applications since the early 1970s.
