Sludge treatment. Alfa Laval supplies wastewater treatment equipment that cover the entire sludge treatment process, including sludge dewatering, sludge thickening, heating, cooling, heat recovery, digestion and pasteurization, as well as advanced control systems for optimizing dewatering and reducing manpower requirements, whilst reducing ...
Sludge is introduced at a central feed well and the supernatant overflows a peripheral weir. The sludge is thickened by the action of a specially designed rake which also moves the thickened sludge to a central hopper, of included angle 60°, for intermittent discharge under hydrostatic head (Albertson, 1992).
biological sludge thickening for municipal sewage treatment plants, or in industrial WWTPs. DAF TECHNOLOGY FOR SLUDGE THICKENING KEY FEATURES AND BENEFITS • Design allows tank construction • Horizontal or Vertical versions (Megacell® only) • High floated sludge consistency (up to 6%) is easy to achieve and maintain
ISP Sludge Thickeners are used to thicken sludge from settling tanks in both municipal and industrial purification plants. Function The ISP Sludge Thickener increases the concentration of the sludge due to its slow moving arms and vertical pickets. This also enables liberation of gas bubbles and aggregation of flakes of sludge.
The physical depth of a separator controls sludge thickening time and is an important parameter in determining thickening capacity. Thickeners and clarifiers can be designed to operate in either batch or continuous mode, ... Other variants include the vertical flow clarifier, ...
The depuration plant with vertical flow static clarifiers for the recycling of wastewater coming from aggregates processing plants, marbles, granites and ceramics is particularly used in the case of limited water flows or in the case of construction sites where space is an issue.
High-efficiency sludge thickener instruction. The deep cone sludge thickener is based on the traditional vertical flow sedimentation tank. The structure of the internal feed cylinder is improved, the efficiency of sedimentation is greatly improved, the plane of the sludge thickening tank body is circular, and the suspended solids settle under gravity.
Circular Thickeners provide a crucial treatment step between upstream process screens, clarifiers, and separators and downstream dewatering and sludge conditioning processes. A well-designed thickener provides storage and equalization, reduces the volume of sludge streams, and increases their solids concentrations.
Thickeners. Thickeners — or Clarifiers, depending on the application — can be used to recover immediately reusable process water, as well as extract fines and other materials. Thickeners are used by mineral and aggregate producers, as well as by environmental contractors in industries such as wastewater management, to separate solids from liquid in a slurry.

SLUDGE THICKENING FS-FNG-001 Page. 2 of 31 1.- SLUDGE THICKENING 1.1.- Objective Fluids leaving the water line create the WWTP sludge line. Two basic operations are sludge pre-treatment and thickening. Thickeners aim at separating the two phases (solid and water) efficiently, increasing solids concentrations, so that the volumes are lower a
A sludge thickening tank with mechanical drive is available for post-settling sludge treatment. Covers are available in a variety of materials to prevent algae growth, protect the water stream, and control harmful vapors/fumes. Access ladders, platforms, and railings can be included to accommodate site specific requirements.
The thickening tank is equipped with slowly moving vertical paddles built like a picket fence. Sludge is usually pumped continuously from the settling tank to the thickener which has a low overflow rate so that the excess water overflows and the sludge solids concentrate in the bottom.
For this field PEMO includes more types of sludge pump for thickened slurry in both horizontal and vertical and submerged versions. Some of them reach a flow rate of 1500 cubic meters per hour. For the transfer of concentrated or thickened sludge we mainly use horizontal types AO / AB and AO / AB / DC with lateral suction series.
ing of sludge aggrevating clogging of the filter cloth. Testing has found that one Foil Doctor Plow assembly is equivalent in thickening action to two conventional fur-rowing plow assemblies. Significantly thickened slurry coming over Foil Doctor Plow. Sludge in compression, filtrate being expressed from slurry. Metal cross support Vertical plastic
Beginners guide to thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the ...
Hycor® ThickTech™. The Hycor ® ThickTech™ Rotary Drum Thickener (RDT) is the industry leading sludge thickener. Its performance is unmatched, with sludge volume reduction of 90% and a 98% capture rate. In addition, this superior performance is achieved with very low amounts of polymer. The RDT system is quite compact and requires less ...
vertical sludge thickeners. What is the Sludge Thickening Process in Water Treatment,Mar 06 2018 · Thickening tanks have slowmoving vertical paddles Sludge flows into the thickening tank and eventually it removes excess water from the solids collecting at the bottom A gravity thickener has a similar process to the tanks but it has a sloped design so that solids collect at …
A Sludge Thickener (optional) with rake mechanism may be utilized in place of the pyramid hopper when applicable. The unique, modular design of the Monroe Parallel Plate Vertical Clarifier allows for easy removal of individual laminar plate modules from the clarifier for inspection. Designed for Your Specific Clarifier Application
Vertical Durability ... High Rate Thickener Design, ... 6.5 SLUDGE THICKENERS A sludge thickener is an auxiliary unit with the specific ... Chat Online; Screw Drain Thickener - MENA-Water. Screw Drain Thickener Sludge Thickeners are widely used in many wastewater and water treatment plants. They are generally placed before filter presses, belt ...
Texipol thickeners are supplied in a pre-neutralised form which means there is no requirement for additional alkali or surfactant addition to achieve thickening. In most applications, Texipol thickeners can be added at any stage of formulating, including post-thickening of systems, thus allowing greater fl exibility when formulating.
They have a limited height and are provided with an upper sludge thickening system. Horizontal decanters are made of stainless steel in their middle and large versions, while the largest ones are made of concrete. The decantation principle is more or …
vertical sludge thickeners in belize. Description Sludge Thickeners is the practice of increasing the solids content of sludge by the removal of a portion of its liquid content A modest increase in solids content can decrease total sludge volume significantly entailing reduced size requirements for subsequent sewage treatment units Sludge ...
Sludge thickening using a decanter centrifuge before a digestion treatment process will reduce the size of the digester, and can be used before sludge storage and liquid land applications. Depending on the utilization of the sludge product (landfilled, land applied or dried) the drier the product the more cost effective it will be for storage, transportation and disposal.
