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.

SPECTRUM TruDepth Standard Spun-Bonded Cartridge
Typically used
SSP-5-20Pentair 20″ Plastic Housings
Typically used
No203GSTBK/BL3/4"Chlorine and Organics Removal
Helps the taste and odour of the liquid and where present, protects RO membranes from chemical attack.

SPECTRUM 870 Economic Carbon Block Cartridge
Typically used
ECB-5-20Pentair 20″ Plastic Housings
Typically used
No203GSTBK/BL3/4"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.

SPECTRUM Reverse Osmosis System
Typically used
SRO-SYS-2.6DI Water Production
The use of a mixed-bed resin of anion and cation, attracts all salts and ions, removing them from the water.

SPECTRUM Deionising Resin Cartridge
Typically used
SRDISPECTRUM Standard Pressure Vessel
Typically used
SV-FK-817CpH Correction
Where acidic water exists or is produced, pH correction cartridges help to increase the pH level.

SPECTRUM pH Correction Resin Cartridge
Typically used
SRCA-20BBPentair 10″ / 20″ Big Blue Plastic Housings
Typically used
BB20BL1"Ultraviolet Disinfection
UV light impedes bacterial growth by sterilising the DNA of microorganisms, suppressing bio-film and bacteria colony growth.

SPECTRUM TruDepth Standard Spun-Bonded Cartridge
Boasting WRAS approval over the ESP, the TruDepth Standard is the best value option for general particulate reduction. With a recognisable mini-grooved construction, the SSP has a higher surface area and enhanced dirt holding capacity over the TruDepth Economic cartridge (ESP).

SPECTRUM Reverse Osmosis System
SPECTRUM RO Systems designed for commercial & industrial operators. 4 systems available to meet RO production levels of 150 to 1250 litres per hour.

SPECTRUM Sabre 4 & 8 – Up to 7.6 lpm
Ideal for residential, light commercial or single-tap outlet applications, these compact single-lamp systems provide effective microorganism control without taking up space or compromising water quality.
