Penguin Series CT carbon treatment chambers use bulk activated granular carbon (GAC) inside re-usable polypro mesh bags in conjunction with post filters to adsorb and reduce organic contaminants from aqueous alkaline and acidic solutions. Out-of-tank chambers are available in polypropylene, CPVC, or PVDF. Sizes range from 5 lbs to 60 lbs of GAC with flow rates to 36 gpm. Chambers may be mounted in parallel for higher flow rates. Penguin series C and CN cartridge chambers can use carbon tubes to carbon treat a given bath as well. Primarily used for carbon treatment of plating baths. These chambers may also be used in the waste stream loop in plating shops.
