Gravity belt thickener for sludge treatment
When dealing with flocculated sludges often found in biological and activated sludge processes, there is a need to efficiently reduce the volume of sludge to lower disposal costs. Sludge thickening is an essential part of wastewater management that requires attention to energy and polymer usage.
Efficiently thicken sludge with minimal energy consumption
The Alfa Laval AS-H Belt Thickener is designed to utilize gravity for thickening dilute sludges and slurries. This solution is effective for all municipal or industrial applications, particularly those involving biological and activated sludge processes. The unit features low energy and polymer consumption, contributing to cost-effective and hassle-free wastewater management. It is constructed with a totally enclosed design to minimize odors and enhance safety and the work environment. Additionally, the thickener’s high throughput rates and high product solids content are facilitated by a simple, robust design that ensures minimal operator attention and maintenance. The system employs a sludge polymer mixing valve and a ramp feeding section for consistent load distribution, optimizing the filtration process. It is versatile enough for both indoor and outdoor installations in effluent treatment plants.
