| Abstract | ||
| Abstract This study aimed to treat the wastewater of Khansaa Hospital in Mosul city by using mud of ( Bentonite , Ninavite & Kaoline ) the experiments were conducted by using the Jar-Test as laboratory scale .The efficiency had been calculated by the following characteristics :-( Chemical Oxygen Demand ( COD ) , Biochemical Oxygen Demand ( BOD5 ) , Oil and grease , Chloride , Sulphate ,Turbidity ,Total Hardness , Calcium , magnesium , Phosphate , Nitrate, Electrical conductivity ( Ec ) & ( pH ) ) . Bentonite showed the best removal efficiency , followed by Ninavite and Kaoline respectively . The removal efficiency was shown at the optimum doses for Bentonite then Ninavite and Kaoline at doses ( 40 , 50 & 60 ) mg/l respectively .Removal of COD give (62%,58%,51%) and (55%,50%,45%) for BOD5 at optimum doses , while oil and grease removal efficiency was (56%,51%&44%).Phosphate removal was (48%,42% & 39%) and efficiency of sulphate removal (46%,41.6% & 38) , while chloride removal efficiency (22%,20% & 17.2%). Key Words: Bentonite Clay, Ninavite Clay, Kaoline Clay, Coagulation,Hospital Wastewater Treatment. | ||
