## Overview

 

 

 

The Hydrotech Beltfilter is made for efficient filtration and draining of sludge and wastewater. It is an automatic, self-cleaning filter specially designed to achieve optimal performance in systems where high solids content in the dewatered sludge is essential.

**Benefits**

- Cost-effective technology
- Small footprint
- Easy to operate, easy to maintain
- Product flexibility
- Sturdy, compact design
- Partnership & development



 

 

 



 

 

 

## Applications

 

 

 

**How it works**

Sludge or wastewater is led into the filter 1 and passes by gravity through the filter belt 2.

The belt is designed as a slowly moving conveyer installed in a stainless steel tank. As the water passes through the filter, the filtering process ensures the efficient removal of particles. These particles are drained on the belt to a high dry matter content. The dewatered sludge is removed at the top of the filter 3 and discharged through a hopper 4 for final treatment.

The belt is further cleaned by a high-pressure backwash system 5 and the rinse water is led either back to the process or to further treatment.

The Beltfilter is normally operated intermittently (demand) controlled by a level switch.
