Evaluation of the Oxidation Process of Blood Contaminated Water in a Bubbler Batch Reactor

EasyChair Preprint no. 5836

Abstract

The wastewater generated in the processing of chicken meat contains a high turbidity due to the presence of suspended solids, organic matter, coliforms, lipids and others. The present work evaluates the H₂O₂ oxidation process of the “Granja Quispe” slaughterhouse wastewater, with a batch bubbling reactor integrated with an airflow, stirrer, and temperature control system; and automated data acquisition for turbidity and pH, implemented with a micro-controller Arduino. The decrease of turbidity with the airflow (F), stirring velocity (V) and H₂O₂ concentration (C) is studied using a 2³ multilevel factorial experimental design. The results show that the higher F, V and C, the greater the decrease in turbidity; being the variable with the greatest effect and statistical significance in the process, the concentration of H₂O₂ and an empirical model was stablished. At conditions of F = 200 ml / min, C = 90 mg / L and V = 300 rpm, t was possible to decrease 52.65% of turbidity, 83.9% of total organic matter and 72.97% of biodegradable organic matter in a time of 112.5 min, , conditions at which the sample efficiently complies with the established standard for non-domestic effluents; constituting an alternative for the treatment of water with a high organic pollutant load
