Phosphorous removal processes. The removal of phosphorous from wastewater involves the incorporation of phosphate into TSS and the subsequent removal from these solids. Phosphorous can be incorporated into either biological solids (e.g. micro organisms) or chemical precipitates. Phosphate precipitation. Chemical precipitation is used to remove the inorganic forms of phosphate by the …

Ion exchange systems for removal of sulfate work in a similar manner, but use a different type of resin. Sulfate ions in the water exchange places with other ions, usually chloride, which is on the resin. When the resin is full to capacity with sulfate, it must be "regenerated" with a salt solution. Water softeners for removal of hardness do ...

The aim of this research was to investigate sulphate removal from mine water by precipitation as ettringite (Ca 6 Al 2 (SO 4) 3 (OH) 12 ·26H 2 O) and the utilisation of the precipitate as a sorbent for arsenate removal. The mine water sulphate concentration was reduced by 85–90% from the initial 1400 mg/L during ettringite precipitation depending on the treatment method.

According to the same study, aluminum salts are used in water treatment as coagulants to reduce turbidity, microorganism levels, and other organic matter. The treatment process usually involves adding aluminum sulfate at "optimum pH and dosage, followed by flocculation, sedimentation, and filtration.' (Health Canada, 1993)
