There are over 1000 HUBER thickeners installed worldwide including many in Australia. The rotary screw thickener is designed for thickening of waste activated sludge prior to dewatering or stabilisation at larger STP’s
Good sludge thickening is required as a prerequisite for the efficient further treatment or dewatering of sewage sludge.
The HUBER ROTAMAT® Screw Thickener RoS 2 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.
The HUBER ROTAMAT® Screw Thickener RoS 2 is designed to handle sludge flows up to 80m3 per hour.
Hydroflux Epco can package Dutch Spiral shaftless screw conveying systems designed specifically for the Huber ROTAMAT® Screw Thickener. Ideally suited to municipal and industrial sludge’s, wet screenings and grit. For more information on Dutch Spiral shaftless conveyors Click Here
The screw thickener consists of a cylindrical wedge section basket which retains the solids contained within the fed sludge.
A screw, slowly rotating with variable speed conveys the solids gently upward through the inclined basket. Water drains through the basket.
The degree of thickening is adjustable by means of a height adjustable weir plate in the sludge discharge and the variable screw speed.
A rotating spray bar cleans the wedge wire periodically from the outside during screw operation
