Described herein, is a method of dewatering a slurry, the slurry being tailings from bitumen extraction of mined oil sand. The slurry is passed through at least one electro-kinetic thickener having a voltage gradient to separate water from the slurry to produce a dewatered slurry. The electro-kinetic thickener may comprise an auger to move the slurry downstream.
Dewatering: Thickening, Filtering, CCD, Water Treatment & Tailings Disposal. ... I was using 6 inch hydrocyclone with 20 % solid by weight (silica sand specific gravity 2.6) in the inlet. The gap between the fishtail valve to the bottom of overflow pipe used is more than 1200 mm. I have tried different inlet pressure from 6 psi to 14 psi.

Figure 3-7 shows the importance of thickening prior to mechanical dewatering. Thickening can be accomplished by partial thickening in a primary or secondary clarifier, a gravity thickener, a dissolved air flotation thickener, a centrifuge, a gravity or low pressure belt press, or a rotary drum device.
A DESCRIPTION OF SEDIMENT DEWATERING METHODS Matthew Englis1, Dewey W. Hunter2 ABSTRACT Whether motivated by a need for disposal of contaminated sediment, a reduction in the size of confined disposal areas, or the scarcity of acreage adjacent to dredge sites, solids containment and dewatering practices have increased in importance in recent years.
Cost Reductions in Sewage Sludge Dewatering and Sludge Thickening Different processes are used for wastewater treatment, depending on the size of the sewage treatment plant. Sewage treatment plant operators use Flottweg decanter centrifuges in different phases of wastewater treatment to dewater and thicken sewage sludge.
Thickening is the first, and frequently inevitable, step in reducing the volume of sludge extracted from the water line. In fact, it is used to optimise the subsequent conditioning, stabilisation and dewatering stages by reducing structure sizes and operating costs.
Polymers for sand, gravel, aggregate and concrete processing, coagulants that is, are typically fed before the thickeners in the 1-5 ppm range while polymers for sand, gravel, aggregate and concrete processing flocculants, that is, are typically fed in the 2-10 ppm range. Polymers: Sand Processing – …

Thickeners. Thickeners — or Clarifiers, depending on the application — can be used to recover immediately reusable process water, as well as extract fines and other materials. Thickeners can be used by mineral and aggregate producers, as well as by environmental contractors in industries such as wastewater management.

From tailings dewatering, thickening and classification, to washing, scrubbing and fines recovery, PHOENIX Process Equipment designs and manufactures a variety of high quality process technologies for markets including aggregate, frac sand, industrial, mining, municipal, and water recycling.
The most common conventional processes include sludge thickening, dewatering, and drying. Figure 9.1 presents the sludge solid content (% of dry mass) during the sludge dewatering processes. After thickening, the sludge mass is usually reduced up to 70% of the initial value, due to water loss, and the solid content reaches 2-3%.
Dewatering Stockpiles . This is the simplest form of dewatering sand sized solids, but usually needs to be preceded by a cyclone or dewatering cone to avoid wash outs due to excessive flow of water. The base of a stockpile needs to have sufficient drainage (ie porosity of the ground, or slope in the case of concrete bases) to prevent pooling.

The higher the VS, the more difficult the dewatering. The dryness achieved will be low, the mechanical properties will be low and the flocculant consumption will be high. When the VS of the sludge is high, it is recommended to add a thickening stepin the process in order to achieve a better dewatering. 1.3.3. The colloidal nature of the sludge:
Originally developed in Japan, the Volute Dewatering Press is patented worldwide, with more than 650 installations. The key to the process is the unique dewatering drum design. This drum is able to achieve both thickening and pressing (dewatering) of the sludge in a single, compact operation.
