Filquip has recently completed trials of its Filter Press units on the wash
out water from concrete trucks. The concrete returned from the job to the batch plant is washed out of the agitator truck into a pit or concrete reclaimer system (See WAM Consep concrete reclaimer). The wash water is separated from the sands and aggregates but contains suspended solids preventing it from being discharged to the sewer or re-used in concrete production.
A three plate trial Filquip filter press was setup and processed 3.6m3/hr of the reclaimed water slurry separating the suspended fines out.
Filtering the reclaimed water reduces the costs of using vacuum trucks to clean out the settled solids in tanks.
