Screw Press Sludge Dewatering Multi Disk Screw Press Sludge Press Machine Product Description sludge filtration which uses the screw extrusion priciple is a new type of solide-liquid separation device. It reaches the goal of extrusion dewatering sludge by the powerful extrusion pressure of changing the screw diameter and distance along with the tiny spacing between moveable and fixed annular plates. Process of Sludge Dewatering Press MDS 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. Sludge Overflow: Sludge is pumped into the dehydrator inlet tank,
and from there, it flows over a triangular overflow discharge into
the flocculation tank. Sludge quantities exceeding the equipment
capacity, are returned through the safety overflow. 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 by 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 produced.
Applications of Sludge Dewatering Press Special pre-concentrating device, no need thickening equipment, widely feed low solids concentration , can be Widely Used in different applications: Exclusive pre-concentration design, applicable sludge concentration of 2000mg/L-50000mg/L; Due to the innovation of the structure design, it is highly suitable to various high and low concentration sludge, most especially for the oily ones. 1. Municipal water and wastewater treatment plants 2. Agricultural/fishery community wastewater treatment plants 3. Industrial waste treatment plants 4. Food/beverage production plants 5. Dairy farming/Meat processing plants 6. Chemicals manufacturing plants 7. Machinery manufacturing/Metal processing plants 8. Laundry wastewater 9. Other (paper manufacturing, building material manufacturing, oilfield associated water accompanied with crude oil mining, etc.)
Model Selection
Dewater Principle 1. Concentration: When the screw pushes the shaft to rotate, the
multiple solid laminations disposed on the periphery of the push
shaft move relative to each other. Under the action of gravity,
water is filtered out from the relatively moving lamination gap to
achieve rapid concentration 2. Dehydration: The concentrated sludge moves forward with the
rotation of the screw shaft; along the exit direction of the mud
cake, the pitch of the screw shaft gradually becomes smaller, and
the gap between the ring and the ring gradually becomes smaller,
and the volume of the spiral cavity becomes smaller. Continuous
shrinkage; under the action of the back pressure plate at the
outlet, the internal pressure is gradually enhanced. Under the
continuous driving of the spiral push shaft, the water in the
sludge is squeezed out, and the solid content of the filter cake is
continuously increased, and finally the sludge is realized.
Continuous dehydration. 3. Self-cleaning: The rotation of the screw shaft pushes the
swimming ring to rotate continuously. The device relies on the
movement between the fixed ring and the swimming ring to realize a
continuous self-cleaning process, thereby cleverly avoiding the
clogging problem common to the traditional dewatering machine. Advantages of Sludge Dewatering Press
Since MDS dewatering press 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 replace filter cloths, self-cleaning, clog-free As MDS 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 rotate up and down to the fixed rings when the gaps between them are cleaned to prevent from clogging.
Low-speed rotating, low noise, low energy consumption - only 1/10 of belt filter presses and 1/20 of centrifuges MDS 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 centrifuges . Full-automatic control, simple operation and management There are no easily blocked pieces such as belt and filtration pore in Multi-Disk Screw Press. Combining with the auto control system, the machine runs very safely and simply and can be programmed according to the requirement of the users. It can operate automatically for 24 hours, unmanned.
Widely Applicable 1. Suitable for sludge in municipal sewage, food, beverage,
chemical, leather, welding consumables, papermaking, printing and
dyeing, pharmaceutical and other industries. 2. Suitable for dewatering of high and low concentration sludge.
When dewatering low concentration (2000mg/L~) sludge, it is not
necessary to build a concentration tank or a storage tank, reduce
construction cost, reduce phosphorus release and anaerobic odor
generation.
