ABSTRACT:
A mobile sewer and catch basin cleaning vehicle dislodges and removes debris in a conventional manner. The dislodged debris is then conveyed into a debris-receiving compartment where it undergoes a two-stage filtration process. The first stage removes the coarser debris from the reclaimed contaminated water. The second stage filters out the finer particulate debris by drawing such water through a finely filtered media surrounding a rotating drum. This filtered reclaimed water is then re-used in the cleaning operations. The extremely fine filtration media is continually cleaned by small amounts of clean water being applied at high pressure through nozzles designed to spray the entire media area as the drum rotates.
