Improve Clarifier and Thickener Design and Operation

Clarifiers and thickeners are essentially ide ntical units; a clarifier produces clean water, while a thickener concentrates a solids slurry as the desired product. In this discussion, thickener will be used to describe both units. Also, a gravity separation of solids from water is assumed to take place.

Trevi Environmental Solutions Gravity thickener

An example of a gravity based sludge thickener is the Dortmund Tank. This type of sludge thickener, very similar to a clarifier, may be applied either continuously or in batch. The water that flows over the overflow edge of the sludge thickener is returned to the purification process while the thickened sludge can be pumped to a dewatering.

THICKENERS Thermopedia

A thickener is an equipment structure used for the continuous gravity settling (sedimentation) of solids in suspensions. Suspension is fed into one or more basins or chambers and, whilst it is passing through, the solids settle out. The thickened solids are removed together with a

Gravity Sludge Thickening Tanks for slurry dewatering LZZG

Working principle . Deep cone thickener is a machine that based on gravity and sedimentation which makes solid-liquid separate from each other.The concentration of pulp waste water could be enhanced from 2%~ 15% to 60% ~ 70% by the machine, the clear water is overflow from the upper part of the thickener,so as to achieve the purpose of sewage purification and solid-liquid separation.

Conventional Thickeners Solid Liquid Separation

The overflow weir that surrounds the tank ensures that the flow that leaves the thickener is distributed evenly in terms of m3/hr/m weir length. During the first year or so differential settling of the tank foundations may cause an uneven distribution so that the entire flow passes over the lower part of the weir which results in high

tailings disposal Outotec

Highly aerated thickener feed that makes its way into the body of the thickener tends to carry fine particles to the surface of the thickener to form froth. This froth causes issues such as the loss of product to thickener overflow (on product thickeners) and can cause reduction in thickener underflow density due to poor flocculation.
