Selection of various coagulants for sugar industry wastewater treatment

Sugar industry is one of the industries that produce a high amount of pollutant since its wastewater contains high amount of organic material, Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). If this waste is discharged without a proper treatmen...

Aluminium sulphate (alum), ferric chloride and polyaluminium chloride (PAC) were chosen to be studied for suitable coagulant. The optimum condition of the coagulant (pH, coagulant dosage, fast mixing speed) was determined by using Design Expert software. Results showed that alum can be used to effectively remove 42.9% of COD and 100% of TSS at high dosage (50 mg/l). The optimum condition of alum was at pH 5.2, 10 mg/l of alum and 250 rpm of mixing speed. This shows that at optimum condition, alum can be used to treat wastewater from sugar industry.
