Removing Sulphates From Water
How to Remove Sulphate from Water - Pure Aqua, Inc
The last water treatment system used for removing sulphate from water is distillation, which boils water and cools the steam until it condenses into a different container. Sulphate, as do other dissolved solids and chemicals stay in the boiling pot. If completely function, distillation systems effectively remove virtually 100% of sulfate from ...

How to remove Sulfate from water
Reverse Osmosis (RO) is a water treatment system that removes most dissolved substances, such as sulfate, from water by forcing the water through a cellophane-like plastic sheet known as a "semipermeable membrane." It can typically remove between 93 and 99 percent of the sulfate in drinking water depending on the type of unit.

A New Process For Sulfate Removal From Industrial Waters
The most common method for removing high concentrations of sulfate from water is through addition of hydrated lime (Ca (OH)2), which precipitates calcium sulfate: Na 2 SO 4 + Ca (OH) 2 => CaSO 4 + 2 NaOH Calcium sulfate, which hydrates to become the common mineral gypsum, has a solubility of approximately 2000 mg/L as sulfate.

The removal of sulphate from mine water by precipitation ...
2016-10-1 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.

The Barium Sulphide Process removes sulphates from mine water by precipitating BaSO4 with BaS. Barium sulphide is regenerated thermally by reducing the BaSO4 with coal at 1000–1100°C for about 15 minutes. The process produces elemental sulphur and CaCO3 as by-products. Laboratory studies achieve typical sulphate reductions of about 95%. Metals such as Fe, Ni, Co and Mn are also
