Sludge & Residual Stream Processing

Sludge processing is a critical component of any wastewater treatment system. Effective sludge dewatering reduces disposal volumes, lowers transport costs, and can enable beneficial reuse of the residual material.

VDZ Aqua offers a complete range of sludge treatment technologies, from initial thickening to final dewatering. The optimal solution depends on sludge characteristics (organic/inorganic content, oily content, dry solids), required capacity, target dry solids content, available space, and energy considerations.

We support clients in selecting, testing, and integrating the most suitable sludge treatment technology — whether that’s a simple gravity table for pre-dewatering, a belt press for robust continuous operation, or a decanter centrifuge for maximum volume reduction.

Polymer conditioning is essential for most sludge dewatering processes. We supply both automatic and manual polyelectrolyte make-up stations to ensure optimal flocculant preparation.
