Abstract
Study depending on using of multi media filter consists of activated carbon, ceramic, sand in order to treatment wastewater of Nineveh Drugs Industry which contained of many amount of chemicals .Raw effluents passed through filters to found the efficiency removal of pollutions .Many tests had done for more than 20 samples such as ;pH, E.C, COD, T.S, S.S , T.H, Ca-H, PO4,NO3, pb, Cu, Zn , Cd, Ca, Mg .The highest and lowest value of organic load value of the waste have been chosen for treatment at rate 5 and 10 m/hr .Comparison carried out between (Activated carbon-sand) filter and(ceramic –sand) filter in order to finding the most effective of removal .The results showed that filter(activated carbon –sand) is more effective than filter (ceramic-sand).Removal efficiency on to (activated carbon–sand) at lowest and highest organic load respectively reached to(92% and 73%) for SS and (%58, % 40) for COD( 85% and 56%) for lead. Lead was the most effective removal from heavy metal. Multi media filter is gave most effective removal efficiency at lowest and highest organic load respectively (95%, 92%) for S.S and (%73 %58 ) for COD and (87.5%, 73%) for lead. The effluent casting to river except cadmium was within limits . COD value was within limits of casting to river at low organic load and exceed limits at high organic load. Current velocity at rate5 m/hr is most effective
