The focus of this paper is to evaluate the performance of a proposed treatment process developed for treating wastewater generated from an abattoir. The flow operation for the treatment was presented in the following sequence: filtration → coagulation/flocculation → filtration → adsorption → filtration→disinfection. To achieve this objective, three samples of wastewaters were collected at designated locations within the abattoir, and were taken to the laboratory for treatment in line with the proposed process. Prior to actual treatment, a preliminary test was conducted in order to ascertain the level of pollution in the abattoir wastewater. This was followed by actual treatment as proposed: Paper filtration, bio flocculation (with chitosan), adsorption (with bentonite clay), further paper filtration and chlorine disinfection. The treated wastewater samples were intermittently subjected to physical, chemical and biological property tests so as to ascertain the performance of the treatment. The results obtained after coagulation/flocculation treatment showed:
