Dewatering on the paper machine takes place by gravity, suction, pressing, and evaporation. Optimizing the operation of the vacuum system is important, since the electricity consumption of the vacuum pumps might be one-fifth of the total electricity consumption of the paper machine. Vacuum dewatering involves large volumes of air …
The drum deck, equipped with replaceable filter grids, supports the filter medium (cloth made from fabric or metal). A vacuum pump provides the necessary gas stream to accomplish dewatering. The vacuum sucks the liquor through the filter medium and forms a filter cake out of the solids, contained in the feed slurry.
A two-stage method for dewatering high-water-content dredged slurry by flocculation and vacuum-assisted prefabricated horizontal drain (PHD) was proposed to increase the dewatering efficiency by ...

The "Rapid Sludge Dewatering System (RSDS)", in which the sludge is dewatered by way of vacuum supported sludge drying beds, was tested for performance, efficiency and applicability. Generally, the RSD-System can be regarded as an alternative to other sludge dewatering systems, especially for small purification plants, for agricultural …
The surface obtained after vacuum dewatering is plain and smooth due to reduced shrinkage. The formwork can be removed early and surface can be put to use early. Fig. 2: Effect of vacuum dewatering of concrete. The …
The objective of this work was to evaluate the performance of biological industrial sludge dewatering by a pilot-scale filter press assisted by electrokinetics (EK). In all experiments the following conditions were kept constant: (1) dry solids content in the sludge feed: 5.0 wt%; and (2) constant electric-current mode.
This study proposes a new method using the combination of flocculation and prefabricated horizontal drain (PHD) assisted with vacuum pressure for rapid dewatering of high water content dredged ...
The difference between dewatering screen manufacturers is small tweaks to a century-old design. (1) We're the only manufacturer to include screens on the sidewalls, which exposes the sand to more screening action to remove more moisture. (2) Combined with a higher g-force, our screens allow deeper sand depths to physically squeeze out more water.

A manufacturer of vacuum systems was looking for high-performance pumps for vacuum waste water collection systems. The manufacturer emphasized the need for pumps that are suitable for vacuum applications, have a high suction capacity and are resistant to solids. The customer opted for Börger rotary lobe pumps type PL 200.
The vacuum sequence generally proceeds in steps; the highest vacuum level continuing until the sludge cake cracks and vacuum is lost. Table 1 presents a typical vacuum sequence. Stage Vacuum Duration (in. Hg) (hours) Gravity dewatering 0 1 to 5 Low vacuum 1 to 4 1 to 2 Intermediate vacuum 5 to 8 1 to 2 High vacuum 10 to 15 1 to 2 …
