Rendering facilities often generate high-load and variable wastewater streams that strain conventional treatment systems. Typical influent contains bloods, fats, proteins, and emulsified greases, along with pit overflows and batch discharges, resulting in elevated COD, BOD, and TSS levels.
Effective pretreatment upstream of anaerobic digestion or aerobic polishing is critical. By stabilizing flows and removing high-strength organics, operators can protect downstream equipment, enhance biogas recovery, improve polishing efficiency, and ensure consistent compliance with discharge standards.
