The Sludge Screw Thickener SST for throughputs of up to 100m 3 h offers an optimal solution for increasing the total solids percentage of sludge, manure, and digestate in municipal and industrial applications. The robust and easy-to-operate SST sludge thickener is available in two sizes and stands out due to its continuous operation modes, low maintenance costs, and low energy consumption.
This sludge dewatering equipment is designed for achieving 5-12 solids depending on the type of sludge. This sludge thickener is optimized to deliver minimum operating costs while provide superior overall results. Drum Sludge Thickener Panels Removable Drum Panels. JWCs Monster Drum Thickener utilizes woven wire mesh for the construction of ...
The HEI Sludge Thickener is an efficient method to gravity concentrate and decant waste sludge. Liquid sludge pumped from a clarifier will have a solids content of 0.5 from cone bottom clarifiers to 2-4 from the rake bottom clarifiers.
The sludge thickener is a central drive type continuous or intermittent thickening and solid-liquid separation equipment. Sludge thickeners are generally suitable for concentrate concentration or tailings dewatering in wet beneficiation operations.
Sewage Sludge Thickener Centrisys THK Series Sewage Sludge Thickener is Specifically Engineered to Achieve High-Performance Thickening of Biosolids.. The non-conical design results in greater G-volume, allowing for the highest capacity of flow to the centrifuge for the thickening of sewage sludge at sewage treatment plants.
The central drive sludge thickener for wastewater treatment consists of a rotating device with a central drive, including an electric motor, a multi-stage reduction gear, a
In general, thickeners provided with a central sludge ditch without scrapper device and which do not occupy more than a sector, must not be recommended, as well as those whose sludge extraction is performed from wells located in the periphery.
The primary objective of sludge thickening is to concentrate the solids, thus reducing the volume of sludge. Thickeners may increase the solids concentration by a factor of 2 to 5 and produce a clarified liquid effluent. Thickening is accomplished by either gravity or dissolved-air flotation.
The rake employs multiple bottom scraping blades that are angled to ensure that all settling sludge is captured and brought to the central sludge well. Thickening pickets and drive lift mechanisms are often utilized when sludge properties warrant additional mechanical agitation.
Salher sludge thickeners are manufactured in GFRP glass fiber reinforced polyester with orthophthalic resins and are used for the dehydration or thickening of sludge produced during primary and secondary treatments. They are truncated cone-shaped equipment consisting of a central feeding chamber and a Thompson perimeter canal. They can be supplied for underground or above-ground installation ...
Jun 18, 2020 A rotary drum thickener RDT is based on the same principle as a gravity belt thickener GBT, in that water drains from the sludge through a retaining porous medium. For an RDT the porous medium is the cylindrical wall of a 0.51.5 m diameter drum which rotates at speeds between 5 and 20 RPM while the sludge continually passes through it.
Mar 06, 2018 Sludge thickening is an important process in treating solid waste. It minimizes the water waste, enabling the re-treatment of biosolids so that they can safely circulate back to waterways. It is vital to use the correct product and municipal wastewater treatment solution, so having an expert on hand will give your company the safeguards of ...
Thus, the solids load entering the sludge thickener becomes 112.1 The solids load escaping in the liquid portion from the thickener is taken as 11.2 The solids load leaving the thickener becomes 100.9. In the dewatering centrifuge, solids load from polyelectrolyte is 0.8

Thickening processes concentrate the sludge by removing part of the free water, i.e. the water not associated with the sludge particles or flocs. The finished product retains the liquid, free-flowing characteristics of the feed, and can therefore be pumped
SLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8 solids, can be thickened to a content of 4 solids, then a fivefold decrease in sludge volume is ...
Currently, the main processes of sludge treatment include sludge thickening, conditioning, dehydration, stabilization and drying, with a variety of physical, chemical and biological methods Liu et al., 2013. Generally, the thickening process can remove the pore water in sludge
The sludge thickener is a machine fitted with a stake and scraper blade structure connected to the central pin that, by rotating in clockwise direction, make the gases present in the water surface and at the same time it allows conveying the debris sludge, etc. into the concrete basin, located in the ...
The quantity of primary and surplus sludge is reduced as a result of sludge thickening procedures and disposal costs are, therefore, lowered. Special stirring and scraping mechanisms reduce the water content of the sludge in the sludge thickening tank and enable a continuous removal of still pumpable, free-flowing sludge into a collection hopper.

When wastewater is treated, sludge is produced. Ovivo thickeners are designed to continuously produce as thick a sludge as possible. Powered by heavy-duty drives, designed to handle the specified torque for 20 years of continuous operation, the sludge is gently mixed by rotating rake arms.
Thus, the solids load entering the sludge treatment units is 122.1 The solids load escaping in the liquid portion from the blending tank is taken as 10 Thus, the solids load entering the sludge thickener becomes 112.1 The solids load escaping in the liquid portion from the thickener is taken as 11.2
