Abstract

This paper synthesized the new copper removal agent(PW-2001) and investigated removal efficiency of copper, COD, calcium, SS and sludge amounts. Removal efficiency of copper were 96.1% and 99.1% with the lime and PW-2001, respectively while COD removals reached up to 38% and 69.6% with the use of lime and PW-2001. The concentrations of calcium and SS with PW-2001 were decreased 2.68 and 4.95 times lower than those with lime. Amount of sludge with PW-2001 was 60% smaller than lime. Quantity of PW-2001 needed for coagulation only reached 58.7, compared to lime standard quantity(100), and total cost of copper removal with PW-2001 was saved 25% more than lime.
