The Tumbl-R unit offered by Novotec is perfectly adapted to treat difficult sludges. Engineered as a stand-alone, self-cleaning dewatering system, it is a perfect alternative to classic dewatering techniques.

Sludge is transported over a stationary filter plate, by rotating oval discs. The longer the sludge travels over the filter plate, the more water is separated from the sludge. The rotating oval disks do not only transport the sludge, they but also keep the filter plate free from clogging. An optional, adjustable endplate regulates the pressure on the sludge and obtains the optimal sludge cake dry matter content.

The unit either works with or without polymer injection, depending on the sludge type. The Tumbl-R is the perfect solution for fiber rich sludge, without risk of blocking or clogging, due to the cutting oval disks. Despite a small footprint, the unit is capable of treating high loads.

A corrosion free construction ensures a long and trouble free life span. Slow turning parts reduce wear and tear on the machine and thus keep the maintenance costs low. In parallel, the energy demand is reduced as well, making this unit very economical in operational cost.

Available as stand-alone unit or in containerized, plug & play solution.
