TECHASE-The most professinal manufacture for solid-liquid separation 2014 IE expo show     Product Description      TECHASE are always focusing on independent technology innovation of themselves.Under the cooperation with Tongji University, TECHSE have successfully developed the new generation of sludge dewatering technology -Techase® multi-plate screw press, a screw type sludge dehydrator that is much more advanced in very aspects than belt presses, centrifues, plate-and-frame filter presses, etc. It features clogging-free, wide range of applications, low energy consumption, simple operation & maintenance.    It has solved several technical problems of other similar sludge dewatering equipment including belt presses, centrifuge machines, plate-and-frame filter press have,  which are frequent clogging, low concentration sludge / oil sludge treatment failure, high energy consumption and complicated operation etc.   Thickening: When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is pressed out from the thickening zone and fall  down to the filtrate tank for gravity.   Dewatering: The thickened sludge moves forward continuously from the thickening zone towards the dewatering zone. With the  pitch of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In addition to the pressure generated by the back-pressure plate,  the sludge is greatly pressed and dryer sludge cakes produce.   Self-cleaning: The moving rings rotates continuously up and down under the pushing of the running screw shaft while the gaps between the fixed rings and moving rings are cleaned to prevent from clogging that happens frequently for traditional dewatering equipment.       Patents:   Techase constantly focus on innovation & improvements of our products to meet the requirements of the market and provide our customers with products of reliability and high performance. So far, we've got tens of patents and varieties of pending technologies on Techase® Multi-plate Screw Press.   Product Feature:   Special pre-concentrating device, wide feed solids concentration: 2000mg/L-50000mg/L   The dewatering part of MSP consists of a thickening zone and a dewatering zone. In addition, a special pre-concentrating device is mounted inner the flocculation tank. Therefore,  the wastewater with rather low solids content is not a problem to MSP. The applicable feed solids concentration can be as very wide as 2000mg/L-50000mg/L.   Since MSP can be used directly to concentrate and dewater the low-solid sludge  from aeration tanks or secondary clarifiers, the users don't have to build a thickening tank or a storage tank any more while they have to when using other types of sludge dehydrators, especially the belt filter presses. Then significant civil engineering cost and floor area are saved.    Furthermore, the phosphorus emission problem caused by aeration tanks or secondary clarifiers can be well prevented.   Fixed/moving rings replacing filter cloths, self-cleaning, clogging-free   As MSP using fixed rings and moving rings as filter media instead of filter cloths makes it especially good at treating oily sludge when compared with other types similar sludge dehydrator. The moving rings rorate up and down to the fixed rings when the gaps between them are cleand to prevent from clogging.       Low-speed rotating, low noise, low energy consumption - only 1/10 of belt filter presses and 1/20 of centrifuges   MSP doesn't need any big supporting equipment such as rollers to work with. The rotating speed is as low as only 2-4 r/min. As a result, it can realize water-saving, energy saving and low noise. The average energy consumption is only 0.01-0.1kwh/kg-DS, only 1/10 as that of belt filter presses and 1/20 as that of centrifugal machines .   Full-automatic control, simple operation and management Typical Cases:   Seletion Table:
