RO membranes are typically capable of removing 90%–99% of contaminants such as total dissolved solids (TDSs) in the water supply. The membranes are usually manufactured as a flat sheet of thin composite membranes consisting of an active polyamide layer (high permeability but impermeable to dissolved salts and particulate matter) supported by a porous polysulphone layer wound round a central collection tube.

Osmosis occurs when two solutions with different concentrations are separated by a semipermeable membrane. In RO water purification systems, the osmotic pressure is overcome using hydraulic pressure, which is applied using a pump to the concentrated side. Water is then driven from the concentrated solution and collected downstream of the membrane.

RO membranes are sized on their water volume production rate and the desired hourly or daily rate of water to be used.

The benefits of these advancements in RO technology has helped to provide pure and potable water that is free of unwanted chemicals, toxins, and other impurities which increases the standard of living of communities and contributes to a healthy lifestyle. Check out  fine selection of reverse osmosis systems HERE , which range from (commercial & industrial), to our membrane systems that consist of nanofiltration, ultrafiltration, and membrane cleaning systems that serve as fantastic and often very necessary pretreatment units.

Qualities of RO Purifiers:

  1. Most effective method when TDS (Total Dissolved Salts) range between 200 and 2000
  2. Reduces the hardness of water which is caused by excessive calcium & magnesium salts
  3. This is the only technology capable of desalinating seawater, to make it fit for drinking.
  4. Besides removing chemicals, also kills all types of germs, viruses, and deadly viruses.see Here http://lotus.co.ke/.
  5. RO Purifiers have pre filtration to work with dirty water.
