Turbidity Removal from Aqueuse Solution by three Materials Coagulates

Abstract

The addition of coagulation chemicals to turbid water, which contains molecules, plankton, and colloids, is known as coagulation and flocculation. Three of Coagulants are the most widely utilized coagulants in water treatment. process were tested for their efficacy in reducing turbidity in this study. Aluminum sulfate (alum), ferric chloride, and date seed powder are the ingredients. Experiments were carried out with synthetically prepared turbid water containing kaolin, and a Jar test instrument was used to determine the best dosage and pH for each chemical. The effectiveness of Alum, Ferric Chloride, and Date Seeds powder was tested at different pH values of 5.5, 7.5, and 9.5, as well as coagulant dosages of 10 mg/l to 50 mg/l, to determine the best operating conditions for turbid waters with turbidities of 60 NTU, 150 NTU, and 300 NTU. The results revealed that pH and coagulant dose affects turbidity removal and the water's turbidity at the start for each of the coagulants used. Over the applied turbidity range, the highest removing turbidity efficiency was within (95.2-96), (94-96.41), and (91.3-94) percent for Alum, Ferric Chloride, and Date Seeds powder, respectively.
