A system for separating solids from a fluid includes a containment vessel having a V-shaped tank in fluid communication with an agitated overflow tank. Baffles within the V-shaped tank provide a series of zones where the fluid is deposited for processing. A shaftless auger at the bottom of the V-shaped tank transfers solids to an area where they are pumped to a first hydrocyclone assembly associated with a first shaker. Overflow from the hydrocyclone assembly and underflow from the first shaker is further processed by a second hydrocyclone assembly associated with a second shaker. Overflow from the second hydrocyclone assembly and underflow from the second shaker are deposited into overflow tank which contains the cleaned fluid.

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.

The present invention provides a fine particle separating apparatus comprising: a first filter part having a first mesh part, mounted therein, for separating fine particles included in sludge according to size, and having a first section and a second section with the first mesh part therebetween; a first flow path mounted in the first section so as to allow the sludge to flow into the first filter part; a second flow path mounted in the second section so as to allow an effluent, having passed through the first filter part, to flow therein; a third flow path connected from the second flow path so as to discharge the effluent to the outside; a fourth flow path connected from one side of the second flow path, and mounted in the second section so as to allow at least a portion of the effluent flowing into the second flow path to flow to the first filter part; a fifth flow path mounted in the first section so as to allow the effluent, discharged by means of the fourth flow path, to pass through the first filter part and then flow therein; a storage tank through which the effluent flowing into the fifth flow path is discharged; and a first pump for generating a flow of the effluent, wherein the first mesh part is rotatably mounted in the first filter part.

The present invention is directed to a drilling fluid reclaimer The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is reclaimed for use with a drilling system.
