| Abstract: | This study fits into the scheme of research work being carried out to develop a wastewater treatment process for the food industry with the possibility of recycling nutrients as a proteinic biomass. A slaughterhouse effluent was submitted to a series of laboratory tests at temperatures of 45, 52 and 58°C. The treatment efficiency was demonstrated by a 90% reduction of chemical oxygen demand (COD) for studied retention times (6, 12, 18, 24 and 30 hours) at 45 and 52°C. The crude protein content collected reached an average of nearly 70% dry basis, and the amino-acids composition was proven adequate for use as protein concentrate for pig and poultry feedings. |
