Reverse Osmosis (RO) is a process where water is forced under pressure through a ‘semi permeable membrane’. The water that passes through the membrane is largely less the salts present in the raw water, the contaminates are rejected by the membrane and flow as a concentrate to waste. With a domestic RO the production of purified water is quite slow and is normally stored in a small tank ready to be dispensed when required.
This Domestic RO unit requires a minimum feed pressure of 2.8 Bar ( 40 psi) to operate correctly.
The pressure and the temperature of the raw water greatly affect the performance of the unit since ‘thinner’ warmer water will pass through the membrane more easily.
The amount of solids dissolved (TDS) in the supply also has to be considered, the higher the TDS the lower the production. These units are not designed to operate on water with a TDS higher than 2000 ppm.
A typical small domestic unit will produce enough high quality drinking water to supply a family of 4. The storage tank holds 6 litres ready for immediate use, the system can produce up to 50 litres per day.
The systems are supplied in a complete kit for DIY fit or alternatively we will be pleased to install and commission the system for you.
