Gravity belt thickener for sludge treatment
Optimize your sludge management by efficiently reducing waste volume and improving solids content through advanced gravity-based separation.
Thickens and Dewaters Sludge Efficiently
The AS-H Belt Thickener from Alfa Laval employs gravity to effectively separate liquid from solids in sludge, making it ideal for municipal and industrial wastewater applications. Designed for continuous operation, its robust construction ensures high throughput rates and enhanced solids content. The system integrates an adjustable sludge polymer mixing valve, optimizing polymer use and reducing energy consumption. It features a fully enclosed design, minimizing odors and enhancing safety. Compatible with both indoor and outdoor installations, it processes diverse sludge types, providing end-products like biosolids and compost feedstock. Easy to maintain with low labor requirements, this belt thickener lowers waste disposal costs while ensuring reliable performance in demanding environments.
