[0002] In wastewater treatment and other fields, filtration is a common operation. By passing wastewater through a filter screen, particulate impurities in the wastewater are filtered out and retained. Existing filtration devices are typically filter boxes equipped with filter screens. They are open filtration devices where wastewater enters through the inlet, passes through the filter screen, and then exits through the outlet to proceed to the next process. The filter media trapped on the filter screen needs to be collected and treated periodically to ensure the filter's filtration capacity.
