Color Removal in Wastewater form Traditional Alcoholic Beverage Factory by Chemical Process : Using Aluminium Sulphate with Burned Husk

Feasibility Study of the enhancing of the color removal efficiency in wastewater using aluminium sulphate with burned husk as a core coagulant in the coagulation process is investigated. The compositions of wastewater from traditional alcoholic beverage factory are given as follows: pH of 4.15-4.24 suspended solids of 204-300 mg/l COD of 4761-5644 mg/l color intensity of 21.05-35.90 S.U. and turbidity of 166-197 NTU. The experimental results revealed that using aluminium sulplate at concentration 0.4 g/l with burned husk sieve number 100 mesh at 2.2 g/l and aluminium sulphate at 0.5 g/l together with burned husk of size 200 mesh at 2.6 g/l can enhance the efficiency of color removal in wastewater. The color removal efficiencies were at 83.06% and 86.00% respectively.
