The Static Sludge Thickener (SST) is a very compact sludge thickening device developed from the original de Hoxar Spiral Separator. PWS has enhanced the original Spiral design and owns the IPR for the technology. The developments have been specifically targeted at reducing the costs of handling sludge for several applications.
In WWTP, the static thickener is mainly applied on primary sludge.Recyling excess biological sludge to the primary settling tank inlet is becoming increasingly rare and, therefore, there are fewer and fewer mixed sludge applications (separate routing of primary sludge and biological sludge immediately upstream from the static thickener must be prohibited: the thickener is not a homogenisation
The thickeners must be preceded by flow balancing tanks to contain and mix intermittent sludge discharges and feed the thickeners at a consistent concentration and uniform rate (Fig. 13.1). In applications where used washwater (without settlement) is mixed with clarifier sludge, the sizing of the flow balancing tanks becomes critical because of
Circular Sludge Thickener. Conventional static thickening for primary sludges. READ MORE. Mobile Sludge Dewatering Unit . Popular solutions for small wastewater treatment plants that combine screening and compaction in one technology. READ MORE. Need a
Filter drum as a thickener is the alternative to the static thickener, centrifuges, and flotation for thin sludge and statically pre-thickened sludge of throughputs of up to 120 m3/h. The optimum result can be obtained at high throughput performance, while achieving a maximum possible degree of thickening at minimal return load and lowest
According to the type of the sludge the installation can be delivered with sludge thickener, flocculation reactor or static mixer. Gravitational sludge thickener– Scraper bridge for radial sludge settler. The thickening process can be worked out gravitational by radial settler made by concrete.
Static Sludge Mixer SSM. Sludge Mixer (SSM) Our new design, reduces chemical consumption with up to 25% optimizes the mixture of organic and inorganic flocculants and watery suspensions of different concentrations. The Sludge mixer can also be mounted in where different media streams to be mixed before flocculation agent is added.
It is at this stage in the thickening process that we might find screens, bar screens, press-screens A cyclone sometimes has to be used to remove grit from industrial, mineral and sandy sludge: the cyclone will be installed at the inlet to the static thickener, on dilute sludge, in order to achieve the best separation performance.
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
It is also very easy to concentrate this type of sludge with a static thickening step just befo-re dewatering. The drawback is that this sludge ferments very easily. 1.2.2. Biological sludge: Biological sludge comes from the biological treatmentof the wastewater. It is made of a mixture of microorganisms.
Center drive sludge thickener is applied for small and medium sized clarifier with central inlet,surrounding outlet and central sludge discharge.It is mainly used for sludge
Filter drum as a thickener is the alternative to the static thickener, centrifuges, and flotation for thin sludge and statically pre-thickened sludge of throughputs of up to 120 m3/h. The optimum result can be obtained at high throughput performance, while achieving a maximum possible degree of thickening
Johnson Screens® Sludgless Thickener provides an economic solution for either sludge thickening or dewatering at small to medium size water, wastewater and industrial effluent treatment plants. The Sludgless Thickener comprises of static
Anyone that’s operated a belt filter press or gravity belt thickener has had to deal with polymer mixing valves. Adjusting or working on these valves has always been a bothersome task. These sludge static

Static Sludge Thickener. Lightweight and compact sludge thickening device offering huge cost savings and environmental benefits. Pure SBR. Compact and flexible SBR plant capable of scaling to
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
At municipal waste water recycling plants, industrial waste water recycling plants, pulp & paper mills etc. to thicken sludge increasing density of the sludge before it settles. FUNCTION The PFT-gate
Two processes can be used to thicken sludge: static thickening, by gravitational settling, and dynamic thickening, a concentration process that calls on dynamic energy. After the thickening phase,
