近年来，电混凝被认为是一种很有前途的混凝方法，在许多水处理领域越来越多地用作化学混凝的替代品。然而，关于它的基础研究还不多。在本研究中，通过一组批量实验，对电絮凝与常规化学絮凝的有效性进行了初步研究。在不同的铝用量和不同的水pH值下，研究了浊度去除效率。此外，研究了zeta电位，以加深对电凝和化学混凝后颗粒特性的理解。结果表明，电混凝除浊效果优于化学混凝。
Recently electrocoagulation has been considered as one of the promising coagulation processes and was increasingly used as a substitute for chemical coagulation in many water treatment fields. However, there have not been many fundamental studies performed on it. In this research, a preliminary investigation was carried out to verify the effectiveness of the electrocoagulation compared with conventional chemical coagulation through a set of batch experiments. Turbidity removal efficiencies, using various aluminium dosages and at different water pH values, were investigated. In addition, the zeta potential was studied to develop understanding of particle characteristic after applying both electrocoagulation and chemical coagulation. It can be concluded from the results that electrocoagulation is more efficient than chemical coagulation in turbidity removal.
