Sludge dehydrator descriptions

Sludge dewatering is the process of separation of components of solid and liquid sludge to minimize the sludge disposal.

Sludge dewatering equipment is not intended to treat the sludge or liquid but; it only separates the liquid components & solid components so it will get easier & cost-effective to handle the separate phases of the disposal. Once the Final sludge has been dewatered, then the liquid is treated in ETP/STP & solid sludge is disposed.

The main purpose of the Sludge dewatering machine is to minimize handling and disposal. Sludge dewateringpress is the most cost-effective method of dewatering and hence helps to sustain the environmental objectives of the company.

Sludge dehydrator process

In contrast to manure dewatering manure, sludge dewatering needs to add flocculant to the sludge before pumping it into the dewatering machine. Then the sludge is transported by the rotating screw along a cylindrical screen at a slow rotating speed (1-4 RPM). As the sludge moves through the press, the pressure and compression is gradually increase, effectively extracting water from the sludge. The water flows out through the screen and is collected, while the solid sludge particles are retained. The solids continue to move along the screw, gradually compacting into drier sludge cake, which is discharged at the end of the screw press. The water content of the dewatered sludge cake is about 75%.

Sludge dehydrator advantages

Screw press sludge dehydrator, also known as multi disc volute screw press, with its advantages of energy saving, stability and high degree of automation, occupies a place in the sludge dewatering operation of the current sewage treatment industry, and is still rapidly recognized. And it was accepted by the market.

It is a new type of sludge extrusion dehydrating equipment, using the screw extrusion principle, through the screw diameter and pitch changes produced by the strong extrusion pressure, as well as the small gap between the floating ring and the fixed ring, to achieve solid-liquid separation. The dewatering screw press is composed of automatic control cabinet, flocculation modulation box, sludge concentration and dewatering device and liquid collecting tank. The automatic control technology can realize the automatic operation of flocculation, continuously complete the sludge concentration and extrusion, and finally return or discharge the collected filtrate.

Sludge dehydrator key features

Liquid outlet with pond depth regulation and energy recovery

PowerTubes adjustable outlets are designed to release the liquid tangential to the rotating direction, supporting the bowl rotation and thereby recovering energy, and minimizing power consumption.

Increased separation performance and energy efficiency

Increasing the pond depth inside the bowl creates a larger volume, leading to longer retention time and improved separation performance. The SuperPond design features a deeper pond and smaller solids outlet diameter, resulting in high solids dryness and clean centrate at high flow rates, as well as low energy consumption.

Rotating feed zone

Low turbulence in the decanter centrifuge bowl is essential for high separation performance and low power consumption. The VecFlow™ rotating feed zone gives you maximum performance with minimal turbulence.

Robust wear protection for conveyor flights

FlightGuard wear protection consists of tiles welded to the conveyor of your decanter centrifuge, providing robust wear resistance and prolonged uptime in highly abrasive applications.

Feed zone with replaceable wear protection

The uniquely designed FeedProtect feed zone ensures gentle product acceleration and minimal turbulence, resulting in low abrasion and power consumption. The FeedProtect design is equipped with replaceable wear-protection liners, ensuring high uptime of your decanter centrifuge.
