 Product Description

The Undersink Reverse Osmosis is neatly installed under the sink with a dedicated faucet installed above the sink. This system has a storage tank which automatically refills the level of water as you use it with a method purely based on pressure (no electricity) in the mains to operate the system of check valves, automatic shut off valve and diaphragm. When faucet is turned on, water comes out of the storage tank then automatically replaces the used amount of water and automatically turns itself off once it is full. 

Reverse osmosis membrane is made from what is called Thin Film Composites (TFC) also called polyamide (PA) membranes. These membranes filter the water at around 0.0005 microns, which is about ½ a millionth of a millimetre, it is so fine that it can strain salt out of the water. The RO membranes work down to the molecule structure of water (H2O), if a molecule of water has an extra atom attached such as a carbon atom the molecule is too large to fit through the membrane and is rejected and goes down the contaminated water line which is commonly referred to as the waste line and expelled from the system. Only water molecules which are H2O are small enough to slip through the membrane (leaving behind the contaminated water molecules) and into the RO product line for you to use.

The re-mineraliser (Alkalizer) which contains crushed Marble and or crushed Limestone, it's primary function is to balance the pH to neutral as reverse osmosis water is slightly acidic because the process removes the calcium from the water which acts as a ph buffer. The material contained in the cartridge is a sedimentary rock which is mostly calcium but also contains trace elements of other minerals, we are prevented from supplying a specification sheet as the amount of re-mineralisation is dependant on the pH of the water, if we had the unit tested at say a pH of 6.0 the cartridge would result in an X factor of re-added minerals which would be misleading if the water in your unit on your water supply had a pH of say 6.4 before the re-mineraliser which would result in a lower added amount. The amount of re-added minerals is totally dependant on the pH of the water out of your system so in short the higher the pH the lower the amount of re-added minerals and the lower the final pH the greater the amount of re-added minerals.

 

Stage 1: Sediment 1 Micron: This removes dirt, sediments, sand, and other physical particles. 

Stage 2: Carbon Block: This reduces chemicals such as chlorine that may be present in your water supply. 

Stage 3: Reverse Osmosis Membrane: It has the Dow Filmtec 200 litre per day TFC membrane, the 200 litres is rated at 50 psi (350 kpa). This system has an auto shut-off device that closes off the in-feed supply when the storage tank has filled.

Stage 4: Alkaline: The re-mineraliser (Alkalizer) which contains crushed Marble and or crushed Limestone, it's primary function is to balance the pH to neutral as reverse osmosis water is slightly acidic because the process removes the calcium from the water which acts as a ph buffer. The material contained in the cartridge is a sedimentary rock which is mostly calcium but also contains trace elements of other minerals, we are prevented from supplying a specification sheet as the amount of re-mineralisation is dependant on the pH of the water, if we had the unit tested at say a pH of 6.0 the cartridge would result in an X factor of re-added minerals which would be misleading if the water in your unit on your water supply had a pH of say 6.4 before the re-mineraliser which would result in a lower added amount. The amount of re-added minerals is totally dependant on the pH of the water out of your system so in short the higher the pH the lower the amount of re-added minerals and the lower the final pH the greater the amount of re-added minerals.
