| Abstract | ||
| Various organic compounds increase in surface water due to the agricultural drains located, the industrial effluents of industrial activities, fish farming cages and random domestic drainage. First, a survey analysis was carried out for five different water treatment plants (WTPs) in Greater Cairo. Coagulation, flocculation and sedimentation were carried as a technique for the removal of total organic carbon (TOC) concentration. Coagulation has been carried out using alum dose between 27-32 g/m3 with average removal percent of (TOC) (16% - 41%), In this study, De-Aluminated Kaolin (DAK)-a waste by-product from alum production-in various dosages between 0.5g - 4 g were added and an average removal percent of (TOC) (45.7% - 77.1%) at contact time of 15 minutes has been found to achieve the maximum (TOC) removal at concentrations of (TOC) (6.6 mg/l) and pH equal 8.3. | ||
