Monitoring the clarity of the overflow and density of the underflow is important for assessing thickener performance. Adjustments in the overflow launder design, froth control devices, or underflow discharge mechanisms may be necessary to optimize the separation efficiency and prevent the loss of valuable minerals. 6. Regular Sludge Removal

Supernatant water overflows at the top of the thickener through overflow launders as shown in Fig. 8.10. The overflow launder at the tank periphery receives water recovered from the pulp and evacuates it slowly to avoid dragging fine particles. A flow of about 0.1 (m 3 /min/m of perimeter) is common.

The invention discloses an adjustable overflow used for a thickener. The adjustable overflow used for the thickener is applied to the large solid-liquid separation dewatering equipment industry. The adjustable overflow used for the thickener comprises a retaining plate, a retaining plate support, a tooth-type stream regulating plate, a rubber depression bar, an …
The Lamella Thickener is an inclined, shallow depth sedimentation device. It performs the same function as a conventional Thickener, but it occupies only a fraction of the space. For an initial understanding of the Lamella Thickener, it is best to restrict the initial discussion to suspensions in which the particles exhibit "free settling."
The Overflow Effluent Launder is a robust structural element built of PP (Polypropylene) and it allows the water to trickle and degas through its gradual flow design. It is used in industrial effluent wastewater treatment and in intensive land based fish farming applications as a degassing / aeration solution. MAT-KULING manufactures custom ...
When cyclone overflow material starts to enter the thickener feed launder the flocculant metering pump should be started and the flow rate adjusted, with flowmeter, to the normal rate of 3 cubic meters per hour. The thickener should remain on recycle until the underflow density approaches the desired 60% solids.
Specifications and thickener rake design. All Thickeners have the same general specifications, varying only as to type of machine. The specifications given for one will cover all. ... Feed, overflow, and underflow systems capable of handling additional material when other thickeners are out of service.
The discharge launder given around the inner edge of the thickener tank at a predetermined height allows the overflowing clear water to exit the thickener. Solids settled in the bottom cone of the thickener are removed by the …
Achieve a higher density underflow with our High Compression Thickener. The HCT has been designed to suit customer needs with a deeper solids bed and higher rake torque than our …
Modification of the header tank and the overflow launder discharging to the overflow water tank was required. The header tank side wall height was doubled to allow for additional volume and head. This modification proved to be inadequate because of excessive splashing over the sides and overflowing under mild upset conditions.
Also these flows generate such force that solids are carried to the overflow launder before settling can occur. ... particles and a clear water is then recovered from the overflow. One of the issues related to using the process water (thickener overflow) is the presence of suspended fine particles which create blockage in transfer pipes ...
McLanahan offers a range of thickener types, including High-Rate, Ultra Rakeless, High-Density and Paste, that are tailored to an individual application. They can be used as stand-alone …
a thickener, including underflow density, the overflow solids content, and the thickener inventory level. The Thickener optimizer overcomes typical thickening limitations, and combines experience with a multivariable, model-based controller. The Thickener optimizer is based on our proven proprietary platforms. has a versatile froth
CCD circuits are often arranged so that the overflow liquors cascade through the circuit while the underflows are pumped. An elevation difference of about 1.5 m was required between tanks for the head requirements of the overflow launder, mix tank, piping and E-Duc feed dilution system. Since the plant is not on a grade, in
Optional sensors for monitoring bed level, underflow density and overflow turbidity ensure optimal operation. Types of Thickeners. McLanahan offers a range of thickener types, ... The role of the feedwell in a Thickener is to mix the slurry feed and flocculant under the right shear conditions to promote the fastest free settling. It is designed ...
The clarifier overflow is typically cleaner or clearer than the thickener overflow would be. Clarifiers, depending on the application – that can be used to recover immediately reusable process water, as well as extracting fines and other materials. Thickeners can be used by mineral and aggregate producers, as well as by environmental ...
The feed in the form of slurry is generally guided by a launder, which is laid at a slope just sufficient for the slurry to flow without depositing any solids. ... Manufacturers such as Dorr-Oliver-Eimco [3] ... The slurry containing 15% solids (by volume) was required to feed a continuous thickener to produce an overflow containing no more ...

Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations – control for disturbances – in the process feed stream to deliver a clear overflow and thickened underflow.
processing, paper manufacturing, and water treatment. More than 90 percent of the nation's soda ash comes from Wyoming deposits. Soda ash production requires a hot dissolution process in which recovery of the hot pregnant liquor is paramount. The liquor is recovered in a primary clarifier where overflow clarity is important.
