 — Aluminum Sulfate. Aluminum sulfate is available in several forms, including ground, kibbled or block. When added to naturally alkaline water (which typically contains calcium bicarbonate), aluminum sulfate produces an aluminum hydroxide floc. Ferric Sulfate. Ferric sulfate is a type of iron coagulant that is second-best to aluminum sulfate.

 — Aluminium sulphate (alum), an inorganic salt, is the most widely used coagulant in wastewater treatment, due to its proven performance, cost-effectiveness and availability. ... Results obtained revealed that, addition of 1 g/L of ferric chloride, 0.4 g/L chitosan and 1 g/L zeolite each to different dose of alum, were able to reduce alum dose ...

 — Specifically, coagulation with ferric sulphate at 20 mg L −1 and pH 7 or higher or at 40 and 60 mg L −1 regardless of pH and with aluminium sulphate at any tested dose and pH 7 or higher increased the removal of MPs after sedimentation alone to around 80%, thus approximating the efficiency reached when centrifugation was included ...
