Sludge treatment  gravity thickening  Sludge Processing

The sludge characteristics also govern the solids loading rate SLR, which is the rate in kg/d at which the sludge dry solids enter the process per unit process cross sectional area. Gravity thickeners are widely used for primary and mixed sludges, but are less effective for waste activated sludge WAS.

5 ways to measure bed level in thickeners   Precision

Figure 1. Thickener and its settling zones. The interface layer, also known as hindered settling region or interface, is defined as the height of the zone between the mud layerpacted zone at the bottom of the thickener and the clarity layer or clarification zone layer with low suspended solids content at

How a Thickener Works

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening

High rate Thickener

The thickeners are generally used in metallurgical field with the purpose of thickening prior to agitation, filtration, in the countercurrent washing of cyan

ALDRUM Sludge Thickener  Mini and Midi

ALDRUM Drum Thickeners work on the principle of conveying polyelectrolyte treated flocculated sludge through a slowly rotating drum filter. The sludge remains in the drum, while the water phase passes through the filter cloth. The sludge concen tration can thus be regulated by adjusting the feed rate, angle and speed of the drum.

Thickening Agent   an overview  ScienceDirect Topics

Traditional cellulosic thickeners work by polymer chain entanglement and hydrogen bonding with water molecules Fig. 14.3 .The advantage of products that only thicken the paint during the aqueous phase is the fact that they operate independently of the system and that the rheological behavior of the paint is predictable .Hydrophobically modified hydroxyethyl celluloses are other

This is normally achieved bypression or high rate thickeners orbination of thickeners and filter presses. High Density Thickened Tailings HDTT are defined as tailings that have been significantly dewatered to a point where they will form a homogeneous non segregated mass when deposited from the end of a pipe Welch 2003.

is reported, and the viscosity drop at high strain rates is again attributed to the breakup of hydrophobic side chains of the aggregates Kennedy et al. 1995 Tan et al. 2000. Even in the absence of grafted hydrophobic side chains, aggregation of polymer chains is an issue for these acrylic thickeners. These materials are assumed to

Conventional Gravity Thickeners

Cost competitive equipment and proven results assure that your process needs are fully considered in the design of each mechanism. High rate thickener units are provided in sizes ranging from 5' to 250' in diameter, and canmodate drive head torques of up to 4 million foot pounds. They are available in shaft or cage driven models.

HIGH RATE THICKENERS   McNally Sayaji

The key advantages of a High Rate Thickener over a conventional thickener are as follows: Some of key features of the MBE High Rate Thickener are The HRT is designed specificallyto operate with flocculantsand hence optimises flocculant consumption.

High rate thickener for coal, 20 m in diameter. 4 1 3 Deaeration tank: Specially designed to reduce air entrainment in order to minimize turbulence and flocculant shearing in the feed pipe. Evenflow 2.0 feedwell: The newly improved feedwell reduces turbulence by using guiding fins for

High Rate Thickeners  McLanahan

High Rate Thickeners separate liquids from solids using hindered settling. Rotating rake arms collect settled sludge and move it toward the center discharge cone. They use minimal amounts of polymers/chemicals to drop the solids, making High Rate Thickeners environmentally friendly.

Implications of Changing the Amount of Thickener in

thickener addition showed Newtonian like behaviour, whereas the higher levels of addition were shear thinning. The time taken for the thickener to reach a near stable viscosity was found to be 10 min. Guidelines for thickened infant formula need to take into account the different levels of thickener addition rates.

High rate Thickener  FLSmidth

High rate Thickeners are designed to provide roughly 12 times the throughput of conventional machines of similar size. The key features for high capacity thickeners are the feedwell design and the feed slurry dilution method. Our patented E Volute feedwellputational Fluid Dynamics CFD optimised energy dissipation and solids

High Rate Thickeners   Solid Liquid Separation

Description. The High Rate thickeners became popular in the mid 1980's and are relativelyers to the sedimentation line of equipment. As already discussed previously Thickeners are aponent in a plant layout and occupy large spaces which may be saved by introducing high rate machines. Furthermore, they are normally positioned far away from the center of the plant so to allow
