Abstract
The industrial wastewater treatment methods include many types of coagulation process which results from the addition and rapid mixing of coagulant with wastewater to remove suspended or colloidal waste materials. Jar test technique was used in this work where coagulants as aluminum sulphate, ferric chloride and polyacrylamide are added by a suitable percentage of each individually to predict the optimum doses of the previous coagulants. Generally the optimum dose for aluminum sulphate which affects the values of the measured parameters was 100 mg/L. The measured parameters which used to test the quality of treatment are chemical oxygen demand, suspended solids, total dissolved solids, conductivity and dissolved oxygen. The results showed that the optimum dose for ferric chloride was 75 mg/L for the treatment of the previous mentioned parameters. However, the best effective dose of coagulant aid was 30 mg/L where the oxygen content was changed to a maximum value of 5.34 mg/L while, chemical oxygen demand was varied to a minimum value of 145.61mgO2/L.
Moreover, the doses of coagulant aid were positively significant correlated to dissolved oxygen values(r=0.892, p≤.0.05) and negatively correlated to chemical oxygen demand(r=-0.855, p≤.0.05), which reflects the high efficiency of the coagulant aid in reducing the organic wastewater.
