Sludge Dewatering Systems Multi Disk Screw Press Sludge Dewatering Equipment Wastewater

 
Product Description

sludge screw type press is composed of screw body, driving device, filtrate receiver, mixing system and frame. When the volute press dewatering operation, sludge will be transported to the mixing tank by sludge feed pump, at the same time, the solid polymer has been added to the mixing tank quantitatively by the polymer feed pump. Mixing motor drives the whole mixing system to make the sludge and polymer fully mixed and then floc will be produced. When the liquid level arrives at the superior level of the liquid level sensor, the liquid level sensor gets the signal to make the motor of screw body operates, then begins to press the sludge which has flows into the screw body. Sludge will be transported to the outlet step by step by the effect of screw shaft; filtrate will flow out by the space of fixed rings and moveable rings

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.
Flocculation: The flocculation tank is stirred with a low-speed paddle mixer, and the polymeric flocculent is dosed into the incoming sludge. The flocculent solution is prepared directly at the wastewater treatment plant, by mixing the concentrated reagent with water, in an independent tank. It is then dosed in sufficient quantities by a dosing pump. The reaction of the flocculent with the sludge, causes clearly defined flakes to be formed in the dehydrator flocculation tank and subsequently brought into the thickening and dewatering drum.

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.

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.
