Slaughterhouse & Meat Processing Wastewater Treatment
Industry Background
Wastewater from slaughterhouses and meat processing plants typically contains high levels of fats, proteins, blood residues, and suspended solids. The sludge generated is characterised by high organic load, odour potential, stickiness, and a tendency to agglomerate. During dewatering, this type of sludge is often highly viscous and oil-rich, making flocculation more difficult. If not properly handled, issues such as belt clogging, sludge leakage, and turbid filtrate can occur. Equipment must therefore provide strong resistance to grease contamination, reliable fabric cleaning, and stable handling of viscous sludge to ensure long-term operational efficiency.
Technical Approach
To address the high fat content and adhesion characteristics of slaughterhouse sludge, Haibar’s belt filter press incorporates a reinforced gravity drainage section to enhance initial dewatering and stabilise sludge mat formation. The pressing zone adopts a strengthened roller structure to maintain uniform pressure when processing highly viscous sludge, improving cake solids content. Food-grade anti-corrosion and anti-grease design elements help prevent long-term fouling. The automatic fabric-cleaning system maintains excellent permeability even under heavy grease load, ensuring continuous dewatering. With a modular system layout, the solution can be adapted to facilities of different scales, delivering efficient, hygienic, and reliable sludge dewatering performance.
On-site Photos
The photos were taken at a meat processing wastewater treatment facility in Central China. The Haibar belt filter press shown is handling sludge with high fat and protein content, operating smoothly with well-cleaned filter fabric and uniform sludge layer formation. The pressing section runs seamlessly, supported by responsive automatic tensioning and tracking systems. These features highlight the machine’s capability to manage highly viscous and grease-rich sludge. Since commissioning, the system has significantly improved dewatering efficiency, reduced sludge transportation costs, and enhanced the plant’s overall hygiene and operational conditions.
