Softening Hard water causes scale which reduces heat transfer efficiency in water systems. An ion exchange system is used to remove the calcium and magnesium from the water. The process is low cost, requiring only salt and small amounts of electricity to operate. |
Turbidity Removal General turbidity removal at high flows can be acheived satisfactorily down to low micron levels using layered media bed filters. Other specialist media may need to be added to improve polishing with certain waters. |

De-Ionisation De-ionisation by automatic Twin Column Ion-Exchange will completely remove the majority of dissolved minerals from raw water. Regeneration of the ion-exchange resins is effected with acid and caustic which must be accurately dispensed for safety and efficiency. |
Triplex Systems A specially developed and patented multi-purpose system which combines an aerator-separator (to oxygenate and degas) with a mixed-bed filter which corrects pH, removes turbidity and many metals, Unlike other systems, the Triplex has the same service flow as backwash reducing the need for higher output backwash pumps. |

Air & Ozone Injection The performance of Iron/Manganese units is enhanced by the addition of Oxygen before the catalytic filter, either from air drawn in through a venturi, or from ozone from an ozone generator. Air injection also helps raise pH by gassing off Carbon Dioxide and reducing Hydrogen Sulphide (bad Taste) |
Membrane Filtration: Reverse Osmosis & Nano Reverse Osmosis is a form of very fine "filtration" acheived by forcing water under pressure through a "semi permeable" membrane. This results in a much higher level (up to 99.5%) of contaminant removal than conventional filtration. When necessary permeate water can be economically "polished" with a disposable deionisation resin. |

pH Correction Acid Water (pHbelow 7) causes corrosion. By passing water through a pressure vessel containing dolomitic limestone, pH is raised from low levels (below 6.5) to a satisfactory level (7+). In addition to corrosion prevention, pH correction is often necessary when Iron or Manganese removal is required |
