Study on highly efficient Cr(VI) removal from wastewater by sinusoidal alternating current coagulation

Cr(IV) pollution in water leads to serious environmental contamination and health risks. Among various wastewater treating methods, electrocoagulation (EC) is widely applied because of its high efficiency. However, there is still a problem of high energy consumption that has to be solved by direct current coagulation (DCC). In this paper, a sinusoidal alternating current coagulation (SACC) technique was used to reduce energy consumption and...
