Chemical Feeding and Control

AWC A-104 is normally fed continuously prior to the final cartridge filter. It should be injected by chemical dosing pump from a dilution tank or directly from the drum to the feedwater line. The amount of AWC A-104 required to inhibit scale formation depends on the quality of feedwater and size of the membrane system. An AWC technical representative will provide you with the specific control range and the approximate dosage rate for your system.
