centrifuges have been used in wastewater treatment since the 1930s. thickening before digestion or dewatering reduces the tankage needed for digestion and storage by removing water. dewatering removes more water and produces a drier material referred to as "cake" which varies in consistency from that of custard to moist soil.inquire now
thickening and dewateringreduce the amount of waste for disposal by up to 90%. onsite thickening and dewatering of sludge is a fundamental part of all current wastewater treatment options to significantly reduce the sludge volume. this has a huge impact on costs inquire now
centrifuges are commonly used for thickening was waste activated sludge. primary sludge is normally not fed to centrifuge as it may contain abrasive material. in addition of being effective in thickening they have additional advantage of less space requirement less odour potential & housekeeping requirement.inquire now
the omega gravity belt thickener is designed for continuous mechanical thickening of municipal or industrial sludge. customers use omega thc in a number of sludge thickening applications: as a final step to increase the dry solids concentration to 68% replacing conventional gravity static thickeners flotation systems and other inefficient inquire now
it is also very easy to concentrate this type of sludge with a static thickening step just before 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.inquire now

sludge thickening different types of equipment mechanical sludge thickening can be achieved with various types of equipment. decanter centrifuges gravity belt thickeners gbt disk thickener screw thickener others flotation static decanter centrifuges are a superior thickening technology even for small and medium sized plants.inquire now
the sludge needs to be disposed of or having further treatment. one of the treatment methods available is thickening the sludge by using solid bowl centrifuges. while prior sludge have the concentration around 0.51 % of dry solid after the thickening process it will contain up to 56% of dry solids.inquire now
in general solid bowl centrifuges have the most widespread use due to high through put capacity and applications for sludge thickening or dewatering. imperforate basket centrifuges are also capable of thickening or dewatering but have lower throughput capacity. discnozzle centrifuges have limited municipal sludge thickening applications.inquire now
the thk thickening centrifuge from centrisys is designed to thicken wasteactivated sludge with little or no . the system produces up to 8 percent cake solids running at flow rates of up to 1000 gpm. applications include secondary sludge primary sludge oxidation ditch sludge digested sludge and mbr sludge.inquire now
high performance centrifuges developed especially for the treatment of sewage sludge and optimised to meet operators specific requirements. the big sludge volumes in wastewater treatment plants require dewatering plants with a high throughput capacity optimal dry residue and energy efficiency to ensure economical sewage sludge treatment and inquire now
sludge dewatering systems centrifuge belt press. dewatering methods centrifuge. the centrifuge separates the water from the biosolids by high revolution to separate water from the solids. the sludge is pumped into the centrifuge where the screw and the bowl are operating at a high revolution creating pressure and separating the water.inquire now
