By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Investigators publish new report on Environmental Management. According to news reporting out of Tamil Nadu, India, by VerticalNews editors, the research stated, "This lab-scale experiment is aimed at demonstrating a treatment system for purification and reuse of laundry rinsing water generated from households. The main objective of the study is to compare the efficiencies of various natural coagulants in removing laundry waste surfactants and other major pollutants from the laundry rinsing water."

Our news journalists obtained a quote from the research from the Department of Civil Engineering, "The treatment system consists of Coagulation-Flocculation, Sand filtration and Granular Activated Carbon (GAC) adsorption. Four experiments were conducted in batch process by varying the coagulants (Nirmali seed and Pectin extracted from pith of Orange peel). Coagulants have been selected due to their local availability at affordable cost and technical feasibility. From the study it is concluded that laundry rinsing water polluted with high turbidity and anionic surfactant treated with Nirmali seeds as coagulant at a retention time of 24 h gives the best results. The treatment system where Orange peel pectin is used as coagulant at a retention time of 24 h is found to be the most efficient one based on the weighted factor."

According to the news editors, the research concluded: "Hence the treatment of laundry rinsing water by aforesaid combination results in better water quality."
