SULFATE SCALE CONTROL IN LOW PH AQUEOUS SYSTEMS

摘要

Scale control agents comprising organic phosphonates, either alone or in mixtures with inorganic phosphonates and also optionally polymers, such as low molecular weight polymeric dispersants. The scale control agents may be applied to inhibit scale formation or deposition in higlily acidic aqueous systems by adding these agents to such systems in amounts effective to inhibit metal sulfate scale formation.
