Economical Viable Liquid Poly Aluminium Chloride (PAC) Coagulation Agent Used to Treat Ceramic Industries Effluent to Remove Suspended Solid

This study was done by using three basic coagulating agents for solid-liquid separation processes to reuse the industrials effluent treatment plant wastewater and reduce an effective amount of chemical consumption as well as cost for treatment of ceramics industries wastewater. The experiment was conducted using jar tester to determine the optimum doses of poly aluminum chloride, alum and lime for treatment of industrials wastewater. The three basic concentration was used in this investigation which were 1% liquid poly aluminum chloride, 2% potassium aluminum sulfate, 4% calcium hydroxide. here 0.05% polyacrylamide was added with each chemical dose as coagulant. These three coagulating substances were used successfully to make the wastewater reusable. The turbidity, color hazen and total suspended solid was reduced up to 90%, 91% and 99.5% respectively. Among those chemicals only 1% liquid poly aluminum chloride dosing was more effective both in physic-chemical and economic suspects for removing significant amount of turbidity, color hazen and TSS. On the other hand, this chemical consumption was lower than that of others. This investigation suggests that using 1% liquid poly aluminum chloride coagulation agent is cost effective treatment process which may be a useful in primary water treatment process for the industrials wastewater.
