Model with integrated pre-thickener, especially suited for low-concentration sludges down to 0.2% TS. Increasing throughput by up to 50% compared to FS

Sludge dewatering performance is greatly improved with a TFU

This model offers an additional thickening step integrated into the flocculation tank, enabling it to handle even lower concentration sludges and raw wastewaters without compromising throughput or cake dryness. Compared to our standard FS series, the additional thickening step increases the capacity by up to 50% when dealing with low concentration sludges.

Advance control modes to maximize performance

Several advanced control modes for the sludge feed pump, polymer dosage equipment, and V-Screw speed constantly work together to optimize and stabilize the dewatering performance. This further reduces the required manpower for operation, decreases polymer consumption, and ensures that the machine is always processing the maximum amount of sludge. Having all parameters connected and controlled from a single point enhances user-friendliness and avoids complicated setup procedures.

Clog-free, even with oily sludge

The machine has a filter element (cylinder) that consists of alternating layers of Fixed Rings and Moving Rings, with spacers in between to maintain a gap that allows filtrate to escape. Inside the cylinder, a single screw conveys and subsequently pressurizes the sludge through the cylinder towards the end plate. As the screw rotates, it drives the moving rings up and down, which cleans the filtrate gap, creating a clog-free and self-cleaning mechanism. Only a very small amount of water at low pressure is periodically used to gently clean the rings from the outside. The design delivers stable dewatering performance even with oily sludge.

No pre-thickening required

The VOLUTE™ integrates pre-thickening, thickening and dewatering into a single machine. This allows direct dewatering of both high- and low-concentration sludges without any pre-thickening system. The GS series especially, with its integrated pre-thickening TFU, is suitable for feed concentrations as low as 0.2% TS, and even below. This enables dewatering of aerobic sludge straight from the aeration tank. This eliminates the costs for construction and operation of thickening and storage systems and reduces odors. On top, it reduces phosporus and nitrogen emmissions back into the waste water treatment plant, by dewatering the sludge when it’s as fresh as possible.
