Unique sludge thickener for efficient thickening of waste activated sludge with over 1000 installations worldwide
Good sludge thickening is required as a prerequisite for the efficient further treatment or dewatering of sewage sludge.
The HUBER disc thickener ROTAMAT®Disc Thickener RoS 2S is a very high performance efficient system for thickening waste activated sludge.
It is a compact and fully enclosed system with very low operational costs, reliable and requires minimal operator attention.
It is designed for smaller sewage treatment plants with capacities with sludge capacities up to 40m3 per hour per unit.
Hydroflux Epco can package Dutch Spiral shaftless screw conveying systems designed specifically for the Huber ROTAMAT® Disc Thickener RoS 2S. Ideally suited to municipal and industrial sludge’s, wet screenings and grit. For more information on Dutch Spiral shaftless conveyors Click Here
