Alfa Laval ALDRUM G3 Sludge Thickeners are ideal for mecha nical thickening of sludge to optimize subsequent processes also increases the separation efficiency in the drum. This, combined with the more gentle treatment of sludge, ensures superior performance as well as low polymer consumption.
CHAPTER 3 SLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction.
Sludge Thickening Wastewater treatment plants commonly use thickening devices to increase the solids concentration at the end of a particular process step within the activated sludge process. Thickening of sludge increases its solids content and reduces the volume of free water thereby minimizing the unit load on downstream processes
Optimising thickener efficiency Sustainability Matters. Dec 3, 2009 The continual improvement of these process steps is critical to Energy and flocculant costs are a major contributor to process costs. from the top of the thickener overflow and a thick sludge of settled solids underflow from the bottom. .
Traditional Gravity Thickening. Changes in sludge quality or process variations often can have negative process affects. Operational changes in gravity thickening processes may not be realized for twenty four hours or more, resulting in inconsistent thickened sludge and over/under dosing of polymer
Sludge conditioning is a pretreatment step to increase the efficiency of sludge thickening and dewatering of sludge. The two most common methods of sludge conditioning are: a) Chemical conditioning: Addition of lime Ca (OH)2. Addition of ferric chloride Fe cl3 Addition of alum AL2 (SO4)3. Addition of organic polymers.
The cost effectiveness of sludge thickening should be considered prior to treatment and/or disposal. 22.214.171.124 Capacity Thickener design should provide adequate capacity to meet peak demands. 126.96.36.199 Septicity Thickener design should provide means to prevent septicity during the thickening process.

xvEPA United States Environmental Protection Agency Biosolids Technology Fact Sheet Gravity Thickening DESCRIPTION Thickening is the process by which biosolids are condensed to produce a concentrated solids product and a relatively solids free supernatant.
Dynamic thickening is mainly used on lightweight, hydrophilic sludge: biological sludge and hydroxide sludge are the speed of the process and dynamic thickening ability to achieve good concentration performances on problematic sludge. The accelerated dynamic thickening of biological sludge is used to: separation efficiency is high.
The sludge thickening system is designed to achieve flocculation with a minimal amount of expensive chemicals. The floc tank has tangential inlet and outlet openings to maximize flocculation by reducing shear from turbulence. The zones can have different size mesh media to augment capture efficiency as the sludge moves along the length of
The High Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. up settling rates to reduce the size of conventional thickeners is closely associated with an improvement in the efficiency of flocculating agents. There are also concepts that resemble sludge blanket

The Ovivo ® sludge thickener is designed to continuously produce as thick a sludge as possible from streams of sludge previously formed and collected in separate settling basins. Included with the thickener mechanism are Ovivo's durable heavy duty drives. The drive is designed to handle the specified torque for 20 years of continuous operation, but we have seen drives still in operation after
HUBER is able to offer all common methods of sludge thickening: screw thickeners, rotation filters, filter belt
However, waste activated sludge thickening by scroll centrifugation is generally considered unfeasible, owing to complications in producing a clear centrate. Suspended Solids Removal Efficiency. Centrate from dewatering sludge is returned to the head of a treatment plant contributing suspended solids to the raw water influent.
Sludge Thichening . Thickening of sludge increases its solids content and reduces the volume of free water thereby minimizing the unit load on downstream processes such as digestion and dewatering. solids capture efficiency if chemicals are not used for bio sludges.
HUBER Solutions for Sludge Thickening Thickening is the first step for reducing the sludge volume by removal of free sludge water. Thin sludge is concentrated to thick sludge.
Jan 12, 2017· Sewage sludge treatment describes the processes used to manage and dispose of sewage Energy may be recovered from sludge through methane gas production Sludge treatment technologies that are used for thickening or dewatering of Fine bubble diffusers are typically the more cost efficient diffusion method,
Large tanks, known as thickeners, are used to separate fine suspended mineral particles from the process water, producing a stream of clarified water from the top of the thickener overflow and a thick sludge of settled solids (underflow) from the bottom.
For example, it comes standard with a sludge thickener (this pre-conditions the sludge prior to dewatering and also prevents maintenance issues like "rat" holing). It also has the largest sludge storage capacity of any clarifier in its class.
A&J Fabtech sludge thickeners are designed for both clean and dirty water. We can supply the optimum solution for separating substances from water.
