Sludge treatment technologies: digestion, thickening, dewatering, drying and incineration
Sewage sludge treatment is more than only thickening, digestion, dewatering and disposal. It has consequences for the whole treatment plant: With sludge-originated biogas, it is possible to increase energy production (electrical and thermal) to over 100% of the power needed in the plant.

The RWQCP is a tertiary wastewater treatment plant that currently treats approximately 33 mgd. Existing thickening processes include in-tank thickening for the primary sludge, and DAFTs for thickening of WAS.
Thickening is provided to reduce the volume of sludge. Two basic types of thickeners work by gravity or flotation and use either continuous or batch processes.
The sludge resulting from this process represents the next challenge for the water treatment industry, in particular the minimizing of its volume. This Sludge Dewatering handbook will present the key parameters to take into account in order to optimi-ze sludge treatment with SNF Floerger’s organic polymers.

With regard to the economical further treatment and disposal of sewage sludge, it is necessary to reduce the sludge volumes produced within the course of the wastewater treatment process. This volume reduction is achieved by the separation of parts of the sludge liquor at different points within the sludge treatment process chain.

Wastewater treatment plants, also called sewage treatment plants or water pollution control plants, remove most pollutants from wastewater before it is released to local waterways. At the plants, physical and biological processes closely duplicate how wetlands, rivers, streams and lakes naturally purify water.

They are a continuously operating machine which thicken sludge by gravity on a revolving porous filter belt. They generally produce a pumpable thickened sludge. They are commonly installed in waste water treatment plants, water treatment plants, food and dairy industries, abattoirs and pulp and paper industries.
Sludge treatment technologies that are used for thickening or dewatering of sludge have two products: the thickened or dewatered sludge, and a liquid fraction which is called sludge treatment liquids, sludge dewatering streams, liquors, centrate (if it stems from a centrifuge), filtrate (if it stems from a belt filter press) or similar.

The relationship of municipal wastewater and sludge treatment to crop production is shown schematically in Figure 3.1. As illustrated, reuse of wastewater for food crop production or in other reuse applications, such as ground water recharge or urban landscape irrigation, typically occurs after secondary wastewater treatment and may …
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 …
Sludge thickening is a a low investment process used commonly in wastewater treatment plants to remove as much water as possible from the liquid sludge. The method involves increasing the concentration of the solids in the sludge …
Sludge treatment technologies that are used for thickening or dewatering of sludge have two products: the thickened or dewatered sludge, and a liquid fraction which is called sludge treatment liquids, sludge dewatering streams, liquors, centrate (if it stems from a centrifuge), filtrate (if it stems from a belt filter press) or similar.
Sludge treament A volume reduction of approximately 30 – 80 % can be reached with sludge thickening before a further treatment. At smaller wastewater treatment plants, where the sludge is driven off regularly, thickening usually takes place directly in the sludge storage tank.
Volume reduction is very desirable when liquid sludge is transported by tank trucks for direct application to land as a soil conditioner [1]. Thickening Techniques Used in Sludge Processes Most common techniques of thickening in sludge processing are given in Table 1. Table 1. Thickening Techniques Used in Sludge Processes [2].
Sludge thickening is important because it is the process used in wastewater treatment centers to increase the solids concentration and decrease the free water. This step minimizes the load on the downstream processes, …
Flottweg decanters for sewage sludge thickening are used in waste water purification in purification plants. This allows you to reduce your operating cost.
Innovative high qualitative machines, plants and stainless steel equipment for municipal and industrial water, wastewater and sludge treatment. Competent in stainless steel - leading in wastewater technology - more than 40,000 installations worldwide.
Treatment of sewage sludge may include a combination of thickening, digestion, and dewatering processes. Thickening Thickening is usually the first step in sludge treatment because it is impractical to handle thin sludge, a slurry of solids suspended in water.
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.
