Hospitals are significant consumers of water. The wastewater generated by the hospitals may contain pathogens, bacteria, viruses, pharmaceuticals etc. In this paper, the review has been done for the treatment of hospital wastewater containing harmful ingredients using electrocoagulation, the reuse of the same water after treatment. Electrocoagulation method is one of the effective methods for the treatment of Industrial Wastewater. Because of its low operation and maintenance cost, high efficiency, time-saving, lower sludge production without any addition of chemicals. The efficiency of electrocoagulation method mainly depends on the treatment time, the conductivity of the solution, distance between electrodes and the current density. The main objective of the study is to remove the solids present in Hospital wastewater by electrocoagulation using Aluminum (Al) and iron (Fe) electrodes. Electrocoagulation is the electrochemical process of treatment of wastewater. Hospital wastewater contains solids, BOD, COD, phenols, radioactive isotopes, pathogens such as bacteria, viruses, blood, body fluid, sweat, contaminated organs, disinfectant, pharmaceuticals as well as hazardous chemicals can be effectively removed by Electrocoagulation method. The factors which affect the electrocoagulation process are current density, treatment time, pH, the distance between electrodes, an initial concentration of the sample, a conductivity of the solution, electrode material. Hospital wastewater effluents discharge in environment may cause serious threat to the environment as well as humans and this effluents also contain solids, BOD, COD, phenols, radioactive isotopes, pathogens such as bacteria, viruses, blood, body fluid, sweat, contaminated organs, disinfectant, pharmaceuticals as well as hazardous chemicals, pathogenic microorganisms and other heavy metals and toxic chemical compounds such as Cu, Fe, Cd, Pb, Hg, Ni, Pt, Cyanide, Phenol and this type of wastewater can adversely affect ecology balance and public health. So there is a need to have effective treatment of the wastewater is a must before discharge into the river or stream.
