The comparative performance of potassium ferrate(VI), ferric sulphate and aluminium sulphate for the removal of turbidity, chemical oxygen demand (COD), colour (as Vis400-abs) and bacteria in sewage treatment was evaluated. For coagulation and disinfection of sewage, potassium ferrate(VI) can remove more organic contaminants, COD and bacteria in comparison with the other two coagulants for the same doses used. Also, potassium ferrate(VI) produces less sludge volume and removes more contaminants, which should make subsequent sludge treatment easier.
评估了高铁酸钾（VI）、硫酸铁和硫酸铝在污水处理中去除浊度、化学需氧量（COD）、颜色（以 Vis400 吸光度计）和细菌的比较性能。对于污水的混凝和消毒，在使用相同剂量的情况下，与其他两种混凝剂相比，高铁酸钾（VI）能去除更多的有机污染物、COD 和细菌。此外，高铁酸钾（VI）产生的污泥量更少且去除的污染物更多，这应会使后续的污泥处理更容易。
