Sludge mixed with a large amount of sand, which caused an accelerated wear, has accumulated within the initial sedimentation basin at the Haifa WWTP.
The proposed solution included:
Pumping of the upper fluids layer using unique specialized pumps.
Entrainment of the heavy sludge toward the pump by means of a hydrodozer.
As a result of the dozer’s entrainment activities, the pool’s pumping lasted about half the customary time and all the sand and sludge were removed.
