CE Certificate Volute Dewatering Equipment with EU Standard for All Kinds of Sludge

BOEEP volute dewatering equipment is certificated by EU, which meets the quality standards of Europe and has been exported to Europe. The volute dewatering equipment is effective for all kinds of sludge.
  • MYDL132
  • MYDL


The main structure of volute dewatering equipment is made of multiple fixed ring and moveable ring with the screw shaft running through it. The front part is concentrating section, and it can concentrate the sludge. The ending part is dehydrating section and it can dewater sludge. The two work steps can be done in one box. The volute dewatering equipment has taken place of the traditional filter clothes and centrifugal filtration method for its distinctive filter model.

Principle of Dehydration

Volute dewatering equipment is a new type of solid-liquid separation device which uses the mechanical principle of screw press. It reaches the purpose of dewatering sludge by the powerful extrusion pressure of changing the screw diameter, distance and the tiny spacing between moveable ring and fixed ring.

working principle of volute dewatering equipment


1. The volute dewatering equipment can not be clogged easily

Special dynamic and static rings make the volute dewatering equipment not easily clogged. Then there is no need to wash it with abundant water to prevent the filter space being clogged, so it has reduced the burden of inside circling and solved the clogging problems that the traditional dewatering devices bring.

2. Continuous and automatic operation

Volute dewatering equipment can control its operation automatically including pumping sludge in, putting in flocculant and discharge sludge cake. The device can operate through the team work of electrical cabinet, polymer feeder, 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 opertarion process. Daily maintenance of the machine can be easy, convenient and continuous all day without manual operation.

3. Operation costs can be saved

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

4. No secondary pollution

The rotation speed of screw shaft is about 2 to 3 revolutions per minute with no vibration and little noise, which can create a very comfortable operation surrounding. The volute dewatering equipment has the self-cleaning function, cannot be clogged, just need a little water to clean, and has no secondary pollution. 

5. Flexible and durable frame

The design of volute dewatering equipment 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 parts that need to be replaced are only the screw shaft and moveable rings, which contributes a long life and durable.

6. Saving engineering investment

Volute dewatering equipment 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.

7.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.

8.Volute dewatering equipment can be widely used to dewater sludge of various industries, such as municipal administration wastewater, food, drink, slaughtering and breeding, printing, petrochemical engineering, papermaking, tannery and pharmaceutical. Innovative structure design makes it possible that the equipment 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 sludge with oil.
