Experimental Investigation on the Treatability of Greywater using Cissus quadrangularis

Abstract The scarcity of finding clean water for drinking has been increased due to pollution, population, and many other criteria. Multiple philosophies exist about the use of reused water for drinking and domestic purposes despite the warning on health and safety issues associated with residual contamination. This study aims to investigate the changes in the chemical parameters of greywater treating it with naturally available material, to analyze its suitability for potable water. This experimental work was done by treating the greywater using chopped oven-dried Cissus quadrangularis, a natural creeper familiar for its medicinal properties. Greywater represents the water from sinks, automatic washers, showers, and also from other kitchen instruments. The chopped and oven-dried Cissus quadrangularis was mixed with greywater and made to contact with water for the various time duration of 15 minutes, 30 minutes, 45 minutes, and 60 minutes. The change in physic-chemical characteristics of the greywater on the addition of Cissus quadrangularis was analyzed for different contact periods. Results indicated that Cissus quadrangularis was found to be more effective in treating greywater, more particularly acidic samples. Treated greywater can be used for domestic purposes except drinking and needs further treatment if preferred to be used for drinking.
