    Pilot-scale fluoride-containing wastewater treatment by the ballasted flocculation process

    A pilot-scale ballasted flocculation system was used to remove fluoride from one type of industrial wastewater. The system included the formation of calcium fluoride (CaF2) using calcium hydroxide followed by coagulation sedimentation. Calcium fluoride was recycled as nuclei for enhancing CaF2 precipitation and as a ballasting agent for improving fluoride removal and flocculation efficie

    F2 Aluminum Chlorohydrate: AC-940

    Aluminum chlorohydrate (ACH) is a complex mixture of highly positive charged aluminum polymer species ranging from Al2 to Al200, and Al13 polymer, Al13O4(OH)24(H2O)12Cl7, is the major component. ACH is used to destabilize the colloidal particles (typically negative charge) allowing them to clump together into a floc. In comparison to other metal-based coagulants, ACH benefits include less pH ...
