The Ramat HaShofet wastewater treatment plant uses a semi-intensive method, which requires very basic maintenance, which includes, as part of the operational activity, removal of the sludge from the settling basins.
At Ramat Hashofet, after years of activity without proper maintenance, the pools were almost completely blocked with sludge.
Laboratory results showed that the treatment process did not occur as expected and the quality of effluents did not meet regulatory requirements.
It was necessary to remove the sludge and clean the pools, while preserving the walls of thebasins, the plumbing systems, the basin cover, and more. it was also important to treat the sludge in order for it to comply with regulations.
Detailed process
- Removal of sludge, using a backhoe to transfer it to the evaporation pools
- Cleaning and washing of the two basins and repairing of the plastic sheets covering the bottom of the basins.
- Loading the sludge onto trucks and transporting it to a compost site, where it could be processed and recycled for various purposes.
- A total of 700 tons of sludge were removed from the settling pond, followed by drying and pumping the remaining water.
