The water was flocculated with alum alone=44 mg/l, pH=7.6 (case NO.1) ; alum =30 mg/l and porcelanite dose =12 mg/l ( as coagulant aids);pH=7.51; Temperature =31.4Co ( case No.2) and alum =23 mg/l and porcelanite dose =18 mg/l ( as coagulant aids); pH=7.6; Temperature =34.4Co (case No.3). In this research optimum removal of turbidity by means of this a direct filtration apparatus was achieved in the case No.2 at G values of around 25 sec-1 , Tf =10 min the percentage removal of turbidity obtained was about ( 90 %) , whereas in case No.1 , the optimum percentage obtained was about ( 84 %) at G = 40 sec-1 , Tf = 20 min and case No.3 , the optimum percentage obtained was about ( 86 %) at G= 30 sec-1 , Tf = 20 min.
