Incoming water is pre-filtered with sediment cartridges initially, this prevents further stages such as the carbon stage from premature blocking. Chemicals such as chlorine, chloramines, herbicides and organics are treated with carbon to protect the RO membranes from chemical attack. RO quality water is produced at this stage.

For further purification, DI resin is used to polish the remaining salts and ions. RO and DI quality water both have pH that is acidic and further treatment is available using calcite cartridges to modify pH levels (SRCA). Stored RO or DI water is agitated through a recirculation loop that passes through an Ultraviolet (UV) disinfection system and 0.2 micron bacteria removal cartridge.

Stages of Filtration & Water Treatment

Sediment Removal

Prevents debris, scale flakes, dirt and particle build up in pipework, tanks, equipment and where present, premature blinding of filtration stages further along the cascade.

Chlorine and Organics Removal

Helps the taste and odour of the liquid and where present, protects RO membranes from chemical attack.

RO Water Production

Very pure water is produced using reverse osmosis membranes to separate the majority of salts and ions from the feed water and sending the salts and ions to waste or re-circulation.

DI Water Production

The use of a mixed-bed resin of anion and cation, attracts all salts and ions, removing them from the water.

pH Correction

Where acidic water exists or is produced, pH correction cartridges help to increase the pH level.

Ultraviolet Disinfection

UV light impedes bacterial growth by sterilising the DNA of microorganisms, suppressing bio-film and bacteria colony growth.
