Fully Automatic Municipal Solid Waste Management Equipment

screw press sludge dewatering machine is ideal for oily sludge with clog-free and self-cleaning mechanism

The clogging of filter mesh decreases the efficiency of conventional dewatering equipments.

TNW's dewatering press is equipped with unique screw press technology, which enables dewatering while automatically self-cleaning the filter mesh. This enables stable and constant dewatering to take place without depending on high pressure flushing water to prevent clogging.

This self-cleaning mechanism enables screw press to be ideal to dewater oily sludge, which easily causes clogging and is difficult to treat with other types of dewatering equipments.

Thickening and dewatering all in one filter drum

screw press adopted the unified structure that serves two functions, thickening and dewatering in the single machinery. The secret lies in the self-cleaning mechanism. The drum filter, because of the clog-free, realizes higher speed of filtering phenomena per filtering area as compared to other methods, and the sludge is instantly thickened by gravity. For this reason, low concentration sludge of about Total Solids 0.2%, as well as thickened sludge, can be directly fed without pre-thickening.

Easy operation/Easy maintenance

Intuitively understandable operation system adopted. Monitoring of the operation settings is made very easy.

Full automatic 24-hour operation without an operator on-site is possible with automatic operation control using various sensors. With this function, manual operation, such as starting or stopping, is not required. Moreover, daily maintenance is minimized, requires no skilled labor neither special knowledge, so that everybody can use it easily.
