A fluid management system including an inlet configured to receive pre-processed fluid is provided. The system includes a filtering apparatus configured to remove contaminants from the pre-processed fluid. The filtering apparatus includes a plate having a first opening. A first manifold pipe is disposed on the plate and includes one or more perforations and a second opening at least partially aligned with the first opening. A second manifold pipe is disposed on the plate and includes one or more perforations. Filter media is disposed between the first manifold pipe and the second manifold pipe and is configured to separate the contaminants from the pre-processed fluid. The system also includes an outlet coupled to the second manifold pipe to receive processed fluid from the filtering apparatus.

The present apparatus is a compact water filtration unit providing modular, highly customizable water treatment. The standardized sump cylinder structure allows interchangeable accommodation of a wide variety of treatment media, filters, and treatment processes. The top-loading sump cylinders provide ease of servicing, while unique cylinder connectors allow a wide variety of treatment types and sequences without increasing the unit's footprint.

A PAG compressor oil conditioning filter element configured for outside in flow includes a proximal and a distal end cap, wherein the proximal endcap includes a central outlet therein, a cylindrical outer wrap having perforations there through on a portion of the outer wrap adjacent the distal end cap, wherein the flow of PAG compressor oil is configured to flow into the element through the perforations in conventional operation, an annular layer of ion exchange polymers beads radially within the outer wrap configured to remove acid from the treated PAG compressor oil, an annular particulate removing micro-glass media radially within the annular layer of ion exchange polymers beads and configured to remove particulates from the treated PAG compressor oil; and a central flow area radially within the particulate removing micro-glass media and in fluid communication with the central outlet.

The present invention relates to a system for contaminant extraction in a borehole extending from a surface of the Earth through a water permeable layer and into an underlying production zone, the system comprising: an outer casing located within the borehole and extending through the water permeable layer; a production pipe located within the casing and extending towards the production zone; a filter assembly occupying at least part of an intermediate zone between the outer casing and the production pipe, wherein the filter assembly is configured to capture contaminants before they enter the water permeable layer and/or before they are released into the atmosphere, the filter assembly comprising: a lower solids filtering stage configured to filter solid contaminants; and an upper fluids filtering stage configured to filter fluid contaminants migrating from the production zone through the lower solids filtering stage; and sealing means for preventing the uncontrolled leakage of contaminants from the intermediate zone. Methods for contaminant extraction, a contaminant filtration system and solid and fluid filter modules are also disclosed.

The invention features a filtration segment having a top seal, a bottom seal and a primary filter core and the method of filtering with the design of the filtration segment. The primary filter core is operatively coupled to at least one opening which is located either on the top seal or on the bottom seal. The filtration segment also includes one or more interior filters surrounding the primary filter core. Each interior filter includes a filter material surrounding a secondary core which is operatively coupled to at least one opening which is located either on the top seal or on the bottom seal. Each filter may optionally include a retaining medium enclosing the filter material. The filtration segment has one or more layers of an exterior filter media which operatively surround the interior filters and are operatively coupled to the top seal and the bottom seal.
