Solving Dewatering Challenges for a US Poultry Processor with Our 403 Sludge Dewatering Press
We recently had the privilege of working with a client in the United States who operates in the organic waste recycling industry. Their business focuses on turning by-products from poultry processing into valuable resources, but they hit a tough bottleneck.
The material they handle
Sludge from a Dissolved Air Flotation (DAF) system used in poultry processing. The sludge contains a small amount of grease and comes in at about 8% solids.
The challenge
They needed to dewater this sludge to increase solids content and reduce free water, making it lighter and easier to transport. More importantly, they wanted the final product to be suitable for composting – a key end-use for their operation. With a flow rate of 5,000 gallons per hour, running 24/7, they couldn't afford downtime or inefficient equipment. The high moisture made hauling expensive and composting nearly impossible.
Our solution – Two 403 Integrated Sludge Dewatering Press Units
We proposed a complete dewatering package: each unit combines the screw press, polymer dosing system, dosing pumps, and sludge transfer pumps into one pre-assembled, ready-to-run system. No hassle with mismatched parts – just plug and operate.
What made it work – customized design
Every client's sludge is different, and this one had that tricky grease content. So we customized the screw speed and added anti-clogging features to prevent oil buildup on the filter screens. We also fine‑tuned the polymer dosing unit to ensure the flocculant is mixed precisely with the feed, creating strong, fast‑settling flocs even in the presence of grease. This personalized approach boosted flocculation efficiency and maximized water separation.
Operational advantages
The 403 press is built for continuous heavy duty. Its gradual pressure‑building mechanism squeezes out water gently but thoroughly, producing a drier cake. The integrated design means minimal maintenance and easy control – our customer can run it around the clock without constant supervision.
The results
With two units running in parallel, they now achieve their target flow rate with ease. The dewatered cake has significantly higher solids content, reducing volume and weight substantially. That means lower transport costs and, most importantly, a product that composts beautifully – exactly what they needed.
Seeing is believing
We're excited to share real‑life visuals of this project. Check out the photos and videos of the equipment in action – you'll see how clean and efficient the operation is.
