THE CHEMICAL TREATMENT OF WASTEWATER DISCHARGED FROM SAUSAGE CASING INDUSTRY

This study focused on effluents wastewater treatment from sausage preparation using physical and chemical treatment by coagulation and flocculation processes.Choice of a suitable coagulant for maximum contaminant removal and reduction in costs is the most important factor.The feasibility of using aluminum sulfate, poly aluminum chloride (PAC) and ferric chloride in sausage wastewater treatment has been investigated.Removal of water pollutants discharged from industrial sausage wastewater is required to comply with the environmental standards.The study was conducted using poly aluminum chloride dosage (40-140mg/l), ferric chloride dosage (40-140mg/l) and alum dosage (100 -600 mg/l) individually.The efficiency of COD, BOD, TSS, Oil and Grease and TKN removal recorded (98%), (97%), (97%), (95%), (97%) respectively using a dose 140 mg/l of PAC.While using a dose 140 mg/l of ferric chloride recorded (96%), (93.5%), (95.5%), (89.4%), (95.4%), respectively and using a dose 600 mg/l of alum recorded (95.6%),(94.3%),(96.5%), (92%), (95%), respectively.
