Design and Function

HUBER Sludge Acceptance Plant RotaShield®

Rotating high-performance screening drum for extreme applications. Reliable, clog-free solids transport through forced guided material transport within the drum. This ensures high solids throughput even with problematic material (wet wipes, grease, stones). Solids washing and dewatering by means of a subsequent screenings wash press, type HUBER Wash Press WAP®.

While wash water is added to pre-wash and homogenise the raw material within the HUBER Sludge Acceptance Plant, the perforated plate of the wash drum retains all particles bigger than the perforation, which are dewatered and then discharged into a skip.

Since only coarse material according to the perforation is separated, the volume of the resultant residues is vastly reduced with virtually the complete mineral material being further treated in the down-stream HUBER Coanda Grit Washer RoSF4. The resultant coarse material can then be further separated into a mineral and organic fraction by means of a coarse material washer.

FAQ

Frequently Asked Questions

Faecal sludge is the sewage sludge from domestic sewage treatment plants. Faecal sludge usually consists of wastewater with a concentrated content of faeces, food waste, toilet paper, sanitary products as well as mineral components.

For the treatment of faecal sludge, a multi-stage system consisting of coarse screen and grit trap can be useful before the faecal sludge is discharged into the sewage treatment plant.

Wherever residential buildings are not connected to a sewer system but use a decentralised domestic sewage treatment plant, faecal sludge accumulates.

This faecal sludge is disposed of via collection vehicles and transported to a central sewage treatment plant or a special faecal sludge processing facility for treatment. The collection vehicles usually empty the faecal sludge into special receptions stations, also referred to as sludge acceptance plants.

Using a sludge acceptance unit before the faecal sludge is fed into the wastewater treatment plant will clean the raw material from undesired matter, such as sanitary products and plastic articles, etc. This cleaning is necessary to keep the load on the sewage treatment plant resulting from the introduced faecal sludge as low as possible.
