CHAUX, GUILLERMO; ROJAS, GLORIA L  e  BOLANOS, LINA. CLEANER PRODUCTION AND FEASIBILITY OF BIOLOGICAL TREATMENT FOR SLAUGHTERHOUSES EFFLUENTS IN SMALL TOWNS: Case: Municipality of Tambo (Colombia). Rev.Bio.Agro [online]. 2009, vol.7, n.1, pp.102-114. ISSN 1692-3561.

Was evaluated the feasibility of biological treatment for the effluent from the slaughterhouse in the municipality of El Tambo (Cauca) and proposed the implementation of cleaner production processes (CPP) in the use of water and some byproducts generated by the plant for slaughter. Conducted workshops for health inspection, flow capacities, volumetric quantification and analysis of physic-chemical byproducts that include BOD₅, COD, TSS, Total Nitrogen, Total Phosphorus, fats and oils, temperature and pH. There are high water consumption: 200 liters/pork and 1800 liters/bovine (higher than the averages of the slaughterhouse of Popayán-Cauca: 100 L / pig and 500 L/bovine); values of pollution parameters: 9024 mg/L COD, 1829 mg/L BOD₅, 1357 mg/L TSS, 889 mg/L N, 26 mg/L P, 79 mg/L oil and grease, pH 7.6. Production of 23 L/bovine ruminal content and 28 L/bovine of blood. The effluent is not readily biodegradable; however, the biological anaerobic treatment is viable means after removal of fat and rumen collected separately by a strict preliminary treatment. Before the design of the wastewater treatment plant CPP must be implemented to reduce the massive consumption of water and seek a proper and good use of available products.
