Treatment of wastewater from the production of meat and bone meal by the Fenton process and coagulation

Abstract Wastewater from the production of meat and bone meal, due to high load organic matter suspended solids, is a significant problem in process its treatment. In this work, we examined method treating wastewater using coagulation with hydrogen peroxide Fenton process. Treatment variants included use variable Fe 2+ /H 2 O ratios 1:5–1:30, doses 3–18.0 g/L H , 5–10 mL/L coagulant PIX 113. The calculated reduction degrees showed that, regardless treatment variant used, greatest was obtained for turbidity (100%), phosphorus (99%), followed by color (97%), chemical oxygen demand (70%), Kjeldahl nitrogen (48%). proposed options can be used as preliminary stage meal.
