TREATMENT OF GREY WATER USING CONSTRUCTED WETLAND SYSTEM

The grey water is the waste water that is generated in the households or office buildings from streams without fecal contamination. Sources of grey water include water from sinks, showers, baths, washing machine or dish washers. As grey water contains fewer pathogens than domestic waste, it is generally safer to handle and easier to treat and reuse onsite for toilet flushing, landscape or crop irrigation. The removal of toxic content in grey water in this era is one of the most needed process by now. A constructed wetland (CW) is an artificial wetland created for the purpose of treating anthropogenic discharge such as domestic, industrial wastewater and storm water runoff. The treatment of grey water for the removal of toxic content using constructed wetland along with plant species is the most simple and widely accepted eco-friendly method for the better treatment of grey water. This paper addresses the treatment of grey water using constructed wetland with Canna Indica plant and reduces the toxic content in grey water. Grey water and treated water is tested for pH, Total dissolved solids, Turbidity, Chemical oxygen demand, Total hardness, Biochemical oxygen demand, Electronic conductivity and the removal efficiency is discussed with the results.
