Anti-corrosion Screw Press Aerobic Sludge Dewatering for Biochemical Pharmacy

This screw press dewatering machine can easily dehydrate the sludge produced by biochemical pharmacy after aerobic and anaerobic treatment with anti-corrosion function.

Quantity:
  • MYDL131
  • BOEEP
  • MYDL

Structure

The main body of volute screw press dewatering is made of multiple fixed annular plates and moveable annular plates with the screw shaft running through it. The front part is thickening department and the ending part is dewatering department. It can thicken and dewater sludge in one box and has taken place of the traditional filter clothes and centrifugal filtration method for its distinctive filter model.

Working Principle

Sludge will be transported to the screw press dewatering part after being thickened in the thickening part. In the advancing process, the pressure becomes greater and greater because of the gradually decreasing filter space and screw distance with the clogging of the back platen. Then the volume decreases continuously, and the purpose of fully dewatering will be achieved.

Advantages

1. The screw press dewatering machine can be widely used to dewater sludge of various industries, such as municipal wastewater, food, drink, slaughtering and breeding, printing, petrochemical engineering, papermaking, tannery and pharmaceutical.


application of screw press dewatering

Innovative structure of the screw press dewatering design makes it possible that the device can be used for all kinds of sludge with high or low density, especially the sludge with oil, and it can be named the invincible opponent to dewater the oily sludge.

2. The device is anti-clogging

The interaction of dynamic and static rings in the operation make the screw press dewatering not easily clogged. Then there is no need to spend a lot of manpower and water to wash it for preventing filter spacing being clogged, so it has reduced the number of water for washing and burden of inside circling and solved the clogging problems that the traditional dewatering devices bring.

3. Operation continuously and automatically

Screw press dewatering can control its operation automatically including pumping sludge in, dosing flocculation solution and discharge sludge cake. The device can operate through the team work of electrical cabinet, polymer dosing unit, sludge feed pump, polymer feed pump without manual operation. The device being clogged, filters running irregularly or other situations that can affect the performance will not be occurred during the whole procedure. Daily maintenance of the machine can be done easily, conveniently and continuously all day without manual operation.

4. Operation costs can be saved

The integrate and compact design saves operation costs of screw press dewatering greatly. Low speed spiral press technology reduces power consumption greatly. The device cannot be clogged, which can reduce cleaning water largely. Operation automatically all day can reduce appreciable manual costs.

5. No secondary pollution

The rotation speed of screw press dewatering shaft is about 2 to 3 revolutions per minute,  with such a slow speed the odor is not diffused, which can create a very comfortable operation surrounding. Besides, the rotation has no vibration and little noise in the operation. The multi plate screw press dewatering has the self-cleaning function, cannot be clogged, just need a little water to clean, and has no secondary pollution. 


6. Flexible and durable frame

This design of screw press dewatering is quite flexible because it dewaters through mechanical extrusion and do not need large drum frame. Almost all the frame is made of stainless steel SS304 or SS316. The replacement parts are only the screw shaft and moveable annular plates, which contributes a long life and durable.


7. Saving engineering investment

Screw Press Dewatering has the function of thickening sludge. It can deal with the aerobic sludge in the aeration tank directly. So it does not need thickening storage unit, which can reduce the space of sewage treatment facilities and construction costs.

8.Improving phosphorus removal function

Sludge will be dewatered in the aerobic situation, so in the sludge thickening tank or storage tank, phosphorus in sludge is not released under anoxic or anaerobic conditions, thereby improving the phosphorus removal function.
