Abstract
The use of coagulation-flocculation process as means of wastewater treatment is gradually becoming more popular. This research work is to evaluate the efficiency of coagulation-flocculation process in the treatment of abattoir effluent. Samples of abattoir effluent were collected from a slaughterhouse at Ede, Nigeria, and Alum was used in the coagulation-flocculation treatment of the effluent. The physico-chemical and bacteriological analyses of the untreated and treated effluent were carried out and these were used in determining the efficiency of the treatment process. The values obtained (from the physico-chemical and bacteriological analyses) were also compared with the effluent standard of Environmental Protection Agency (EPA). Coagulation-flocculation process is performed efficiently in reducing the contaminant level of Colour, TDS, Turbidity, Conductivity, TSS, Total Hardness, COD, Coliform, metals and other pollutants from the effluent.
Highlights
Coagulation is the process by which particles become destabilized and begin to clump together; it is an essential component in water treatment operations [1]
3.1 Jar Test It was revealed from the jar test results that the mean coagulant dosage (Alum) required to treat 500ml of abattoir effluent is 150ml
PH The value for the pH of the abattoir effluent was 5.150±0.044, after coagulation, the value increased to 5.840±0.157
Summary
Coagulation is the process by which particles become destabilized and begin to clump together; it is an essential component in water treatment operations [1]. Wastewaters often contain pollutants that are present in colloidal form. In such cases the colloidal suspension may contain organic materials, metal oxides, insoluble toxic compounds, stable emulsions and material producing turbidity. The primary purpose of the coagulation/flocculation process is the removal of turbidity from the water. The chemical and electrical means of water and waste water treatment can be achieved by using coagulation as the most important physico-chemical operation [2]. Management of wastewater from the red meat processing industry is an important issue. Due to the specific characteristics of wastewater, such as irregular discharge and considerable organic and biogenic loading, it can be difficult and costly to treat.
