A tank system may be conventional and fixed, or mobile, such as a fracking fluid or other tank trailer. A drain port thereof is fitted with an adapter connecting a snorkel system to drain liquids from near the top of the liquid level in the tank. A snorkel head at the extreme distal end of a tube near the longitudinal center of the tank is suspended by a system of buoys. A flow field controller plate resists formation of vortices near the snorkel head, so it can operate as near the surface as possible, withdrawing the highest grade oil efficiently. At its exit, the proximal end of the tube drains oil through an inner conduit of an adapter at a penetration in the wall of the tank. The adapter forms an annulus around the inner conduit draining tank bottoms directly from the tank.

The water purification system may include a floating platform having a ramp extending from an edge thereof at a downward angle into the body of water, a primary impoundment area extending from a top portion of the ramp onto the floating platform, a pair of sub-impoundment areas attached to an end of the primary impoundment area distal from the ramp, at least one hydraulic cylinder and at least one accumulator attached to the sub-impoundment areas, and a nanofiltration system operatively attached to the at least one hydraulic accumulator. Water may be configured to flow from the body of water onto the ramp and through the system, exiting the nanofiltration system as purified water.

There is disclosed a liquid filter system that includes a liquid filter apparatus configured to self-clean without removal of the filter apparatus from the filter system. The filter apparatus uses both a filter media for filtering solids as well as a spin motion imparted to fluid being filtered so that centrifugal force can remove solids from the liquid being filtered. The liquid filter system also includes a gas pulse nozzle in fluid communication with the liquid filter apparatus and is configured to flow gas into the filter media to expel water and debris trapped in the filter media without removing the filter media from the filter system.

The present invention provides for a multi-stage water treatment system for a plurality of aqueous solutions generated in municipal and industrial processes, e.g., oil and gas field operations, poultry processing, meat processing, dairy processing, and mineral extraction among others. A sequence of different processing steps is carried out, based on the characterization of the composition of contaminants present in the water to be treated. The steps to be carried out include chemical reaction in a series of reactor tanks, sedimentation in slanted plates chamber, air flotation and disinfection, hydrocarbon recovery by a scraper located in a flotation cell. A series of conventional methods are selected to be applied in series for the removal of the contaminants. The process design of an integrated chemical reaction, sedimentation and oxidation system to be used in water treatment of aqueous effluents is presented which is suitable for municipal and industrial processes.

A field water purification system filter is described. The filter includes a water tight enclosure formed between two layers of a polymeric material, an inlet and an outlet are coupled to the water tight enclosure. A filter envelope including a quantity of filter media is inside the water tight enclosure. The water filter having a minimal thickness when not filled with water. The filter envelope is formed by a first set of bonded segments of the two layers of polymeric material. The filter can also include an outer channel having a first side formed by the water tight enclosure and a second side opposite from the first side. The second side can include a second set of bonded segments of the two layers of polymeric material interspersed with a set of nonbonded segments, the nonbonded segments defining openings in an intermittent barrier between the outer channel and the filter media.
