A water treatment system comprises a container, a closure system, at least one loop structure, and remediation media. The container defines a container chamber, a container opening, and at least one container edge. The container opening allows access to the container chamber. The closure system is arranged to allow the container opening to be selectively opened and closed. At least one loop structure is secured to the at least one container edge. The remediation media is disposed within the container chamber. The container is formed of material that allows water to pass from an exterior of the container to the container chamber and thereby come into contact with the remediation media within the container chamber.

A membrane filter apparatus for splitting a feed into filtrate and retentate is provided. The apparatus comprises a body chamber, a feed inlet disposed on the body chamber, a retentate outlet located in the body chamber, a feed distribution tube connected to the feed inlet, and a filter assembly having a filter. The feed distribution tube has a length sufficient to cause the feed to enter the body chamber at a feed distance from the filter assembly of no greater than 50% of a total length of the body chamber. The feed flows across the filter in a direction parallel to a surface of the filter assembly. The filtrate passes through the filter assembly and the retentate flows through the body chamber in a direction antiparallel to the feed flow through the feed distribution tube and out through the retentate outlet.

A method of producing permanently structured water, several products based on superconducting material, such as food, cosmetics, medicals, jewelry, cleaning and radioactivity-reducing product, and various uses of a superconducting material.

The present invention relates to a method for treatment and/or purification of water, in particular wastewater or drinking water, preferably for the adsorptive removal of inorganically or organically-based, impurities, such as trace substances and/or micropollutants, wherein, in a counterflow filter device, e.g. a counterflow adsorption filter column, the water that is to be treated and/or that is to be purified firstly, and, secondly, an, in particular particulate, adsorption material are conducted in a counterflow direction. In particular, a procedure is followed in such a manner that the water to be treated and/or purified is passed through a bed of the adsorption material present in the counterflow filter device for the adsorptive removal of impurities and the bed is exchanged and regenerated by preferably continuous removal and supply of the adsorption material in counterflow to the water that is to be treated and/or that is to be purified.

An exemplary power system utilizes turbines configured within a water intake conduit to the desalination processor to produce power for the desalination processor. Water intakes are configured to provide a natural flow of water to the desalination processor though hydrostatic pressure. One or more turbines coupled with the water intake conduits are driven and produce power for the system. The desalination processor incorporates Graphene filters to and may include a structured water system to increase the H3O2 concentration of the water prior to Graphene filters. Discharge water may be pumped back into the body of water but be separated from the intakes. A secondary power source, such as a renewable power source, may be used to produce supplemental power for the system. Power produced may be provided to a secondary outlet, such as a power grid, all above and/or underground.

A system and method for treating sour water, including flowing sour water and a stripping agent in a countercurrent flow with respect to each other in a sour water stripper column to remove hydrogen sulfide from the sour water into the stripping agent to give treated water, discharging the spent stripping agent (having the hydrogen sulfide) from the sour water stripper column through an ejector to an injection compressor, and injecting the spent stripping agent into a hydrocarbon reservoir.

The invention described herein is that of an outdoor drain filter useful for maintaining the operability of an outdoor drain despite the accumulation of debris that would otherwise obstruct the outdoor drain, resulting in flood prevention of surrounding areas. The outdoor drain filter of the present invention is placed above and around an existing outdoor drain or may be integral with a drain cover or drain reservoir. The outdoor drain filter comprises upper and side filtration means allowing the free flow of water therethrough. The outdoor drain filter further comprises a diverter comprising at least one air vent and at least one lateral pipe that defines a maximum water level to which water will accumulate around the outdoor drain before being diverted into the drain through the diverter. The outdoor drain filter may a manufactured unit or of modular construction.

Described herein is aerobic granular sludge gravity-driven membrane system, methods of making and using thereof are described. The aerobic granular sludge (AGS) integrated with a gravity-driven membrane (GDM) filtration system is an energy efficient wastewater treatment system that takes advantage of AGS reactor systems integrated with gravity-driven membrane system to reduce membrane fouling and produce microbiologically and chemically safe water. The AGS-GDM system includes at least an AGS reactor tank containing raw wastewater and granular sludge and a membrane tank including one or more gravity-driven membrane(s).

A diffusiophoretic water filter has improved inlet, outlet and membrane structures. A support is also disclosed as are method for manufacturing and assembling the diffusiophoretic water filter.

An apparatus for degrading the organic fraction of sewage by means of active biomass, in particular active sludge particles, comprising: —at least one tank (1) adapted to contain the sewage and said active biomass; —at least one hollow structure (6, 106, 206), adapted to be at least partially immersed in the sewage, provided with at least one first opening (61) for letting in the sewage and with at least one second opening (62) for letting out the sewage, wherein the ratio between the area of the at least one first opening (61) and the area of the at least one second opening (62) is equal to at least 5:1; —air delivery means (7, 70) adapted to introduce air inside said at least one structure (6, 106, 206); wherein said at least one first opening (61) is proximal to said air delivery means (7, 70) and said at least one second opening (62) is distal from said air delivery means (7, 70), so that the air delivery means (7, 70) are adapted to generate a flow of sewage from said at least one first opening (61) to said at least one second opening (62).
