Study of landfill leachate coagulation using hybrid coagulant of copperas/lime

Population growth and rapid industrial expansion has contributed to substantial amount of waste generation that subsequently lead to increased demand for landfill sites. Leachate is a harmful sub-stance that leaks from the landfill site consisting of vast amounts of organic and inorganic pollut-ants...
