Before comprehending the various types of sewage sludge treatment plants which can be in common use, it is important to get a solid idea of the material that is handled by these plants. Sludge may be the material that remains after sewage is treated within a sewage treatment plant. It is made up of the byproduct of dealing with wastewater. It ty[ically consists of solid, semisolid, or slurry material. Sludge may be produced through several processes. There are two types. Primary sludge, which is produced through the action of chemical precipitation, sedimentation or other processes. Biological management of wastewater results in the production of activated waste biomass. It is not necessarily unusual for primary and secondary sludge to become combined just before further treatment and eventual disposal.
The purpose of a sewage sludge treatment plant and dealing with sludge before final disposal are:
A) To reduce sludge volume.
B) To stabilize organic materials.
A sewage treatment plant has a variety of functions.
The 1st of these is usually to thicken the sludge. The primary reason just for this is that it is simply not feasible to deal with slurry suspended in water. This procedure normally takes area in a gravity thickening tank. This can decrease the number of sludge by around 50%. There is an alternative where bubbles are fed from the sludge, forcing the solid waste towards the surface of the tank creating a layer of thickened sludge. This is called 'dissolved-air flotation'.

A second treatment is known as digestion. Within this biological process, organic compounds are decomposed - the effect becoming a stable substance. The process reduces the quantity of solids present. The procedure also offers the benefit of destroying pathogens - and makes the whole process of drying the sludge easier. Typically the most popular method of achieving it is a two-stage digestion system that utilizes bacteria in a environment where oxygen is not present. The bacteria (inside a heated environment) convert proteins and fats into smaller water-soluble components. The process is an almost closed cycle with a second tank allowing the product of your first tank to be digested by bacteria into biogas - which can be then accustomed to heat the 1st tank. Occasionally, this co2 and methane could also be used to provide power to the sewage sludge treatment plant. There are additional refinements on the process including thermal hydrolysis wherein the sludge is placed under pressure and heated - then released in a tank, in which the sudden drop in pressure bursts the cell walls from the organic matter.
The final stage is dewatering. With this process, the sludge is distributed on a bed of sand to dry naturally and drain with the sand bed. Following this stage is done the sludge has evolved in character and may be handled and disposed of as being a solid. That disposal could be at ba landfill or you can use it as fertilizer.
The importance of sewage sludge treatment plants must not be underestimated. As urban areas become more population-dense the disposal of wastewater becomes an urgent issue.
