DQO AND TURBITY REDUCTION IN POULTRY SLAUGHTERHOUSE EFFLUENT TREATED BY ELECTROCOAGULATION

Abstract

Due to the high production of broilers, the effluents from this production become a major environmental impasse due to its high organic load, recalcitrant characteristics and difficult assimilation into the environment. Therefore, alternative methods such as electrocoagulation are seen as potentially efficient in their treatment. This study aims to evaluate the possibility of using electrocoagulation in the treatment of effluent from a poultry slaughterhouse with a high organic load, without using additives, through the analysis of reduction of Chemical Oxygen Demand (COD) and turbidity of the effluent, varying the hydrogen potential (pH) and the reaction time. The best conditions found were the time of 60 minutes and pH 7, obtaining 68.1% of COD removal and 78.3% of turbidity reduction. The treatment without addition of additive salts proved viable to be used as secondary treatment, mainly because it is fast.
