Systems, devices, and methods for providing nutrient removals in an up flow filtration storm water system for treating water to very high clean levels using filtration media. A filtration media can be supported by a screen above a floor in a vault allows for incoming storm water to pass into a void space above the floor into the screen and filtration media and then out an outlet to the vault. The filtration media can include recyclable and/or natural particles. Layers of river rocks can be placed on top of and below the filtration media. The captured debris can drop to the floor. The long lasting filtration media can be cleaned by being backwashed.

The present disclosure relates to a filter apparatus (1) for mechanically filtering a liquid (W). The filter apparatus (1) includes a filter chamber (5) for containing a plurality of filter elements (7) that form a filter pack (29) for filtering the liquid. The filter chamber (5) has a liquid inlet (12) and a liquid outlet (14). The filter apparatus (1) includes means for introducing air into the filter chamber (5) through one or more air inlets (25) to agitate the filter elements (7). The filter chamber (5) is substantially sealed and the air introducing means (22) may be configured to draw air into the filter chamber (5) as liquid is drained from said filter chamber (5). In certain embodiments, the filter chamber (5) may have a substantially constant profile or a substantially continuously tapered profile along its longitudinal axis (X-X). The present disclosure also relates to methods of filtering a liquid (W).

The present up-flow water filtration system is made up of three or more layers. In the example of three layers, each layer is individually rigid and capable of supporting loads above it, and each serves a separate function. These layers include the inlet layer on the bottom of the system, the outlet layer at the top of the system, and the central layer in between which contains the filter media. Additionally, the system includes one or more vertical ports that are open above ground and that extend into the central layer and provide access to the central media containment layer for maintenance. There are also several layers of textiles which form the flexible outer casing, as well as internal membranes to separate the different layers and components of the system. Some systems may include inlet and outlet pipes, but other inlet and outlet configurations are possible.

A novel fluid filter includes a partially permeable elastic bag encapsulating a filtration medium, and providing pressure to prevent channeling. A receiver with one or more apertures fits at least partially within the filtration bag to receive treated fluid. A cover may be placed over a tube of the receiver to prevent filtration medium from exiting system. An upper portion of the filtration bag is impermeable, while the lower portion of the bag is permeable. The fluid path flows over the top and up through the lower section and through a major path through the filtration medium.

Disclosed are systems and methods for waste water treatment. A filtration gel includes about 30-45% by weight poly(ethylene) oxide, about 30-40% by weight propylene glycol, about 10-20% by weight glycerin (at least 65% pure), about 5-10% by weight NaCl, about 1-5% by weight fumed silica, about 1-6% by weight silica dioxide, and about 0.5 to 5% calcium as mixed salts.

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.

A filtration system includes a bin having a base, an inlet configured to receive contaminated fluid, and an outlet. The bin further includes a plurality of metal chips positioned on a plate, such as a perforated plate, above the base of the bin. The contaminated fluid, such as contaminated coolant, may flow through the inlet toward the base of the bin and pass up through the plate and the chips to filter away contaminations.
