Reverse Osmosis (RO), also known as hyper-filtration, is the finest filtration known.
This process will allow the removal of particles as small as ions from a solution.
Reverse osmosis uses a membrane that is semi- permeable, allowing water that is being purified to pass through it, while rejecting the contaminants that remain.
The RO membrane uses crossflow technology which continually passes water across the membrane thus flushing away the rejected contaminants. When the reservoir tank is full, water flow stops completely.
The reject ratio is normally about 75 to 85%, meaning for every litre of pure water collected, 4 to 5 litres of reject water is flushed away. While this may at first seem excessive; to produce 5 litres of pure water takes the same amount of water as used in a two minute shower.
Because of the ultra fine membrane used in RO, reject rates for nearly all contaminants are very high; typically around 96- 99+%, depending upon the contaminant and available water pressure.
Combined with the sediment and activated carbon filters, a quality RO system will remove bacteria, protozoa and viruses and significantly reduce organics, salts, metals, nitrates, pesticides and many more contaminants.
Easy to operate, with instant access to pure water, RO’s require very little maintenance and have an operating cost for the average family of around 4c per litre.
Minimum Pressure : 275 kPa (40 psi)
Maximum Pressure : 600 kPa (90 psi)
Above 600 kPa use a Pressure Reduction Device
