A dewatering screw (or screw press) is a mechnical device used to separate liquid from solid waste by compressing the sludge against a filter screen. The process involves removing excess water, returning it for reuse from wastewater sludge, which reduces volume and makes disposal easier.
Reduces Sludge Volume
Removes water from biosolids, significantly decreasing sludge handling and disposal costs
Improves Plant Efficiency
Minimizes the burden of downstream equipment and reduces hauling frequency
Automated Operation
Continuous, low-maintenance operation with minimal intervention
Energy Efficient
Uses mechanical pressure instead of heat or chemicals for dewatering
Compact Footprint
Ideal for facilities with limited space
Enhances Final Disposal
Produces drier solids that are easier to transport and dispose of
This is a cost-effective method for sludge dewatering that enhances overall treatment efficiency, especially when handling materials prone to compaction or cohesion.
Agriculture and Wineries
Efficiently handles organic-rich solids from seasonal or batch operations with low maintenance requirements.
Decentralized or Rural Communities
Compact, low-energy solutions for remote or space-limited facilities that need dependable solids management.
Food and Beverage and Industrial Manufacturing
Used to manage high-moisture sludge and reduce disposal costs.
Ideal for small to mid-sized plants seeking efficient sludge volume reduction with minimal operator oversight.
Supports on-site sludge thickening and volume reduction in systems with variable loading and limited staffing.
