From an environmental point of view, the sewage
treatment process is still far from being environmentally
sustainable. There is an urgent need for the development
of a more sustainable treatment process. Some of the
possibilities include electrochemical treatment,improvement of the mitigation of toxic pollutants, high temperature sludge treatment processes, and membrane
separation processes. Electrochemical process is a
promising treatment method due to its high effectiveness.
Its lower maintenance cost, less need for labour and rapid
achievement of results [5], [6]. Other alternative solutions
to wastewater treatment problems are still needed.
