The Process of Reverse Osmosis

 

The Reverse Osmosis process is utilised in the Pure Water Systems Undersink Series 3000 & 7000 Purifiers. The advantage of the Reverse Osmosis purifier, is that it contains either three or five stages of purification (depending on the model installed).

Osmosis is a natural process which takes place, caused by a pressure differential, in a liquid medium.

Liquid, on one side of semi-permeable, physical barrier, under pressure, will eventually find it's way through the barrier. Reverse Osmosis (as the name suggests) is the opposite, where the natural process of Osmosis is forced into reverse. 

How does this occur? Well, in the case of water, there is pressure applied (house water supply pressure) to the incoming water. The pressure forces the pure, fresh water, through a semi-permeable membrane. The membrane has microscopic pores, only allowing the fresh water to pass through, preventing any other matter from passing through the barrier, including sediment and suspended particles. This provides the most effective water purification available.

Combining the sediment removal and the carbon filter, in the Pure Water Systems Undersink Purifiers, with the Reverse Osmosis Membrane, makes these systems, very efficient and a cost effective solution for domestic and commercial water purification.

Reverse Osmosis Purifiers will provide safe, clean and fresh tasting drinking water, for the entire family for many years.

STAGE 1     CARBON SEDIMENT PRE-FILTER

  • Extra fine mechanical filtration which effectively removes suspended particles (dirt, rust, silt, algae, etc.) to protect and extend the life of the Membrane.

 STAGE 2     REVERSE OSMOSIS MEMBRANE

  • This top of the range Membrane with Ultra-fine filtration will effectively remove and reject dangerous heavy metals (lead, copper, mercury, zinc, aluminium, etc.) as well as micro organisms (Bacteria, Viruses, Giardia, Cryptosporidium, etc.). The Membrane will also remove minute and very fine suspended matter, mineral ions (Fluoride, Sodium, Nitrates, etc.), turbidity and Radio Active Elements.

STAGE 3     CHEMICAL POST FILTER

  • A unique Carbon Block Filter is used to remove the remaining residual toxic chemicals such as Chlorine, Trihalomethanes (Chloroform etc.), Pesticides, Herbicides, Insecticides,
    as well as a wide range of volatile organic compounds. 

STAGE 4     DI REMOVAL CARTRIDGE 

  • Specially designed for the finest ultra high purity removal of inorganic matter ie. heavy metals and salt removal. Enables prolonged contact time of 12-15 minutes for maximum filtration. 

STAGE 5     CARBON POLISHING POST FILTER

  • Provides final polish and superb tasting water.
