Water or wastewater filtration systems and processes have a filter tank having a floor and sidewall defining a filtration zone, an influent conduit, and an effluent conduit. One or more filtration members in the tank having filter media, and one or more cleaning members adjacent at least some portions of the filter media. Generating an effluent stream by generating a pressure differential across submerged portions of the filtration media, causing water in the influent to flow from outside to inside the submerged portions of the filter media. A prime mover rotates the filtration members. A blower and chamber for creating a reduced pressure condition in each of the cleaning members when they are non-submerged, the chamber receiving wet solids removed from non-submerged, wet solids-laden portions of the filter media by the non-submerged cleaning members subsequent to submerged, fouled portions of the filter media being rotated out of the filtration zone.

A water surface garbage salvaging device, comprising a demihull, a large garbage salvaging device and a small garbage cleaning device; wherein the large garbage salvaging device is arranged on a front portion of the demihull, and the small garbage cleaning device is arranged on a rear portion thereof; the large garbage salvaging device comprises a paddle wheel, slipways and a large garbage storage bin; and the small garbage cleaning device comprises a filter mesh, a guide rail slider mechanism, a lifting mechanism and a pulley system, a hanging bracket is arranged above the filter mesh.

The disclosure provides a filtering device comprising a housing, a blocking member and a screening member. The housing includes a body, an inlet end and an outlet end. The housing forms an accommodation space. The inlet end and the outlet end are respectively formed at two ends of the accommodating space. The inlet end is capable of receiving fluid. The blocking member is capable of splitting the fluid into a plurality of fluids and collecting the non-fluid composition of the secondary fluid having a first size. The screening member is disposed between the inlet end and the blocking member, and the screening member is configured to receive the secondary fluid to limit the non-fluid composition having a second size of the secondary fluid to the screening member. After the secondary fluid passes through the shield and the screening member, the secondary fluid is output from the outlet end.

A self-contained .[.portable.]. waste water evaporating apparatus is shown. A solar-operated submersible pump pumps waste water from just under the surface of a waste water pit, through a pair of automatic backflushing filters and out misters located around the bank of the waste water pit. At a predetermined pressure across the automatic backflushing filters, the automatic backflushing filters are reverse cycled, one at a time, to backflushing particles back into the waste water pit. Periodically, the misters are purged and/or cleaned to remove particles therefrom. In response to sunlight, solar panels provide DC voltage directly to the submersible pump. If pressure from the submersible pump gets excessive, a pressure relief valve removes the excess pressure.

A scum filtration system is used to separate, collect, capture, and remove surface scum and contaminants from a body of standing water. The scum filtration system includes at least one treatment assembly, a pumping system, and a main support structure. The at least one treatment assembly is used to filter scum, contaminants, and other similar material from a body of water such as, but not limited to, a pond or lake. The pumping system is used to drive water from a pond or lake into the at least one treatment assembly. The main support structure is used to support the at least one treatment assembly. Further, the main support structure is used to maintain the arrangement of the at least one treatment assembly.
