Used in RO units, at no time should there be a Free Chlorine residual in RO feed water. Even very low levels of chlorine in the feed stream will result in irreparable oxidation damage of the membrane. Therefore operators should ensure that oxidants do not enter the RO system by using common pretreatment methods for reducing chlorine levels by absorption onto activated granular carbon filter media. All Chemical GNC100 and PNC200 are most cost effective carbon based compounds available for the removal of Free Chlorine residual and many types of odours such as hydrogen sulphide (H2S), ammonia (NH3), Volatile organics, Off-gas from tank vents, decomposition odours from greenhouses, and general industrial odours.
- GNC100 is a granulated form activated carbon and is used in many wastewater plants and general industry.
- PNC200 is a powdered form activated carbon and is used in many wastewater plants and general industry.
