Stage 1 - Prefiltration

The purifying process begins with a sediment reduction cartridge that traps dirt, lime rust, mud, hairs and other particles that can affect taste and appearance of water. This stage also protects the RO membrane from fouling and abrasion.

Stage 2 – Pre-carbon Filtration

The carbon cartridge is designed to eliminate bad taste and odours as well as removing chlorine and chemicals (see chart below)

Stage 3 – Reverse Osmosis Membrane Process

Water is forced through a very fine semi-permeable membrane which filters water to the highest quality (molecular level). 99% of all total dissolved solids are then eliminated, leaving the purest water behind

Stage 4 –Activated Carbon Filtration 

This is the final stage of the Reverse Osmosis System, whereby a final polish is performed via a second carbon filter cartridge

Stage 1 - Prefiltration- The purifying process begins with a sediment reduction cartridge that traps dirt, rust, mud, hairs and other particles that can affect the taste and appearance of water. This stage also protects the RO membrane from fouling and abrasion.

Stage 2 - Membrane Process- This is the primary component of 'Raindance' RO purifiers and features the latest technology membrane that can separate up to 98% of dissolved metals and salts from ordinary tap water.  Raindance RO membranes are capable of rejecting ionic contaminants down to five angstroms in size.  One amgstrom is one tenth the size of a millimetre.

Stage 3 - Contaminant Rejection System-  Another unique feature of RO membranes is that they are mostly self cleaning.  The Raindance purifier has been designed and constructed by skilled specialists and the RO process will reject and flush down the drain the contaminants that would otherwise enter your body.

Stage 4 - Reduction of Volatile Organic Chemicals- While the RO process will reject incredibly small contaminants, it must at the same time be sufficiently permeable to allow hydrogen and oxygen to pass through.  As a result, some gaseous and low molecular weight chemicals and cancer causing compounds such as chloroform pass through the membrane.  These potentially dangerous contaminants are effectively reduced by the Raindance bacteriostatic chemical reduction and water polishing final filter carbon cartridge.

For wall mount and undersink applications choose the Raindance unit to best suit your needs.  Pure water storage tank and full installation kit is supplied with every undersink unit. Reverse Osmosis gives you protection from Giardia and Cryptosporidium Cysts along with rejection shown in the chart below.
