High washout factor due to intensive washing
The HUBER Screenings Wash Press WAP/SL/HP operates in a batch mode. Screenings either drop into the launder tank directly from a screen or conveyor, or they are flushed into the tank through a launder channel. After a batch of screenings has been fed, the tank is filled up with wash water and agitated for an adjustable period by means of an impeller. The feacal matter is loosened and removed from the screenings by high turbulence and shear. The washing intensity is selectable and can be adjusted to suit the specific screenings quality.
After the washing cycle has been finished, an automatic valve opens and the wash water drains through perforations in the trough. It returns, together with the faecal matter, to the wastewater flow.
Reduced disposal costs with high pressure
The washed screenings are further conveyed into the press zone where they are dewatered by means of a sturdy compacting screw. In the following automatically controlled second press zone the screenings are constantly compacted and dewatered under high pressure to a DS content of up to 60 %. Especially wear-resistant and solid materials in the conical high-pressure unit ensure reliable long-term operation of the plant. The press water from the screenings compaction is collected under the high-pressure unit and discharged along with the wash water which is rich in carbon. Automatic cleaning with water of the press and wash water collecting tank under the machine and the complete high-pressure unit is possible. The washed and compacted screenings are finally transported through the conical discharge pipe into a skip.
