HUBER Grit Treatment Process RoSF 5-VR
Treatment of grit from wastewater treatment plants and sewer systems by means of a grate separator / grit washer
- Loss on ignition of the grit/gravel fraction < 3%
- Coarse material separation size: 35 mm
- Only one drive unit
- Reduced disposal costs
The dewatered raw materialis fed into the intermediate storage tank directly from the tanker or by a wheel loader. A screw conveyor inside the tank transports and doses the untreated material into the subsequent grate separator where wash water is introduced to wash and simultaneously separate the coarse material.
Any coarse material > 35 mm is separated from the grit and gravel, dewatered and discharged into a container.
The grit/gravel/organics/water mixture <35 mm is passed from the separator directly into the COANDA Grit Washer or grit trap inlet. Also the existing pump in the grit trap delivers grit into the Grit Washer where mineral particles are separated and washed to obtain the fractions of washed grit/gravel and coarse material.
