2017-7-10 During the last few years, environmental sector has shown a largely growing interest in the treatment of different types of wastewater by electrocoagulation (EC). It has recently attracted attention as a potential technique for treating industrial effluent due to its versatility, treatment efficiency, low cost, and environmental compatibility. This technique uses direct

What Are the Three Stages of Wastewater Treatment?

2018-12-6 There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment. In some applications, more advanced treatment is required, known as quaternary water treatment. This stage deals with part per million to part per billion levels of contamination and often involves oxidation or fine filtration processes.
