ROCHEM Group has a wide range of products catering to Water Purification and Wastewater/Sewage Recycle/Reuse:

Fluid is forced across the surface of a semi permeable membrane, under pressure, the fluid stream is divided into two sections, a clean (permeate) and unclean portion (concentrate). .------------------------------------------------------------------------------------------------------------------------------------

The majority of dissolved salts, metals, organics, bacteria and suspended solids are unable to physically pass through the membrane and are discharged in the concentrate. The pure water (usually of drinking water quality) is recovered   .-----------------------------------------------------------------------------------------------------------------------------------

This membrane process is used to separate Targe molecular substances. It will reject all bacteria and is effective to separate oil from water. .-----------------------------------------------------------------------------------------------------------------------------------

Almost like RO, it also removes many of the harmful metals and organics. However, it will allow sodium chloride (salt) to pass through. .-----------------------------------------------------------------------------------------------------------------------------------

A cross flow process typically used to remove suspended particles, down to the sub micron range (0.02 micron). -----------------------------------------------------------------------------------------------------------------------------------
