Electrocoagulation (EC) Design
The removal of heavy metals from industrial waste has become one of the most essential applications in wastewater treatment in terms of protection of health as well as the environment. These heavy metals are known to be among the most common pollutants found in industrial wastewaters, pose serious health hazard, and are environmentally-unfriendly because they are not biodegradable and tend to accumulate in living organisms
The EC has been used for the treatment of various types of wastewater and effluents containing algae, phosphate, sulfide, sulfate, sulfite, fluoride and heavy metals ions such as; Fe2+, Ni2+, Cu2+, Zn2+, Pb2+, Cd2+
EC is a simple and efficient process where the production of the coagulating agent is managed in situ by means of electro-oxidation of a sacrificial anode.
The flocs formed as a result of coagulation creates a sludge blanket that entraps and bridges colloidal particles that are still remaining in the aqueous medium.
