Thickener Feed System Design WesTech
2016-6-14 Thickeners often require dilution of the feed to improve settling rates and flocculant consumption. Dilution systems that rely on specific gravity differential between the feed and supernatant are often limited. WesTech’s AirLift™ dilution system uses an airlift pump to draw clarified water evenly from the thickener surface into the feedwell.

Thickener evolution a testament to customer commitment
2021-6-11 In response to this request, we built a 125m-diameter thickener, with a 10 M lb-ft peripheral traction drive and 20 M lb-ft mechanism design — but in this case, with our proprietary P-DUC forced/pumped dilution system. The pumped dilution relied on four operating P-DUC pumps to achieve the high dilution flowrates.

Understanding Polymer for Thickening and Dewatering
2022-7-9 There is an optimal temperature range for dilution water. A water heater is recommended for dilution water below 4 °C (39 °F). Dilution water over 38 °C (100 °F) may damage polymer chains. SUMMARY. Polymers are excellent flocculants critical for use as a solids conditioner prior to thickening and dewatering equipment.

Thickener Operation. During thickener operation, feed enters the feedwell, via a feed pipe or open launder. In order to promote settling, it is increasing to dissipate this energy. In some cases, flocculants or coagulants are added to the feed to agglomerate particles and improve settling. Feed dilution may also take place.

Thickeners McLanahan
High-Density Thickeners discharge an underflow mud with a yield stress between 50-100 Pa., which can be pumped with a centrifugal slurry pump. They are commonly characterized by having higher side walls to provide enhanced compression effects, a steeper floor slope to assist with moving the solids to the discharge area and a low-profile rake

Sludge treatment − gravity thickening Sludge Processing
2020-6-18 A common variant on the gravity thickener design is the picket fence thickener. This technology is fitted with a stirrer comprising a series of relatively closely-spaced vertical arms, and is therefore similar in appearance to a picket fence. For both designs, the sludge enters the centre of a cylindrical tank and flows out to the periphery.
