Abstract
A composition for minimizing biological and/or colloidal fouling is described, which includes an anionic antiscalant and a cationically charged biocide. Further, a method of controlling fouling is described and achieved by introducing a formulation of the present invention into an aqueous system which uses a separation membrane. The compositions used in the present invention are compatible with such separation systems and preferably prevent membrane fouling.
