Abstract:
The need of the hour relies on finding new but sustainable ways to curb rising pollution levels. The accelerated
levels of urbanization and increase in population deplete the finite resources essential for human sustenance. In
this aspect, water is one of the non-renewable sources that is running out very fast and is polluted drastically day
by day. One way of tackling the problem is to reduce the pollution levels by decreasing the usage of chemicals in
the process, and the other is to find ways to reuse or reduce the contaminants in the effluent by treatment
methods. Most of the available water recycling or treatment methods are not sustainable. Some of them even use
toxic chemicals in the processing steps. Treatment of organic wastes from industries is a challenging task as they
are hard to remove. Electrocoagulation is one of the emerging water treatment technologies that is highly sus tainable and has a comparatively cheaper operating cost. Being a broad-spectrum treatment process, it is suitable
for treating the most common water pollutants ranging from oils, bacteria, heavy metals, and others. The process
is also straightforward, where electrical current is used to coagulate theprences of
carcinogens in these waste water increases the need for its treatment towards further use. The present investi gation is made as an extensive analysis of the emerging carcinogens and their various sources from process
industries, especially in the form of organic waste and their removal by electrocoagulation and its coupled
techniques. The paper also aims to ascertain why the electrocoagulation technique may be a better alternative
compared with other methods for the removal of carcinogens in organic wastewater, an analysis which has not
been explored before.
