A capture unit for use with an antimicrobial application unit may include an upstream filter and a downstream filter. The upstream filter may be positioned to receive effluent from the application unit and to filter solid components from the effluent. The resultant upstream effluent filtrate may then be passed downstream to the downstream filter. The downstream filter may be used to filter an antimicrobial component from the upstream effluent filtrate and the resultant downstream effluent filtrate may be suitable for disposal as wastewater discharge. The antimicrobial is preferably a quaternary ammonium compound, is more preferably an alkylpyridinium chloride, and is most preferably cetylpyridinium chloride.

A disc filter includes a filtrate holding tank disposed below a series of disc-shaped filter members supported on a drum. Filtrate from the holding tank is used to backwash filter media on the disc-shaped filter members. Filtrate is discharged from the holding tank via a filtrate conduit. Bypass water is directed through a bypass conduit in the disc filter and mixed with the filtrate downstream of the filtrate holding tank. This assures that the filtrate used to backwash the filter media does not include bypass water.

A cylindrical filtration filter includes a cylindrical filter main body. The filter main body is constituted by at least two split filters. Each of the split filters has an arc shape in cross section. Each of the split filters includes a filter element for filtration and side frame bodies provided along side portions of the filter element. The side frame body of one of the two split filters adjacent to each other includes a first facing surface having an uneven shape. The side frame body of the other split filter includes a second facing surface having an uneven shape complementary to the first facing surface. The first facing surface and the second facing surface are fitted to each other when the filter main body is assembled.

A cleaning system for a screen of a rotary screen separator for processing feed material comprising liquids and solids has a housing, an air source, and a conduit system. The housing defines at least one housing chamber, at least one inlet opening, and at least one outlet slot. The conduit system is operatively connected between the inlet opening of the housing and the air source. Air flows from the air source through conduit system, through the inlet opening, into the housing chamber, and out of the housing chamber through the at least one outlet slot in at least one air flow stream extending along a flow plane. The housing is arranged relative to the screen of the rotatory screen separator such that the air flow stream impinges on the screen to remove debris from the screen.
