An industrial wastewater and hydrocarbon treatment system including of a plurality of reactors and treatment modules that allows the application of principles of chemistry and quantum physics, dissociating electrons from the atoms or chemical elements contained in the hydrocarbon contaminated water. This invention advantageously allows the separation of water and oil in an efficient way, through the use of electromagnetic pulses with low amperage, and a series of filters.

Disclosed are remote oily water treatment systems, including systems and related methods of remote oily water treatment with point-of-treatment discharge of treated water. In a preferred embodiment, (a) oily water is treated at a location proximate to where the oily water by passing the oily water through a tank containing a medium defined by at least one polymer mixed with activated carbon and (b) treated water is discharged at the point-of-treatment of the oily water.

A water supply system for aircraft that is mounted on an aircraft to supply water to a plurality of water supply outlets in the aircraft. The water supply system for aircraft includes a tank for storing water, a water supply pipe, and an ultraviolet sterilization device. The water supply pipe extends from the tank, branches and is connected to each of the plurality of water supply outlets, and supplies water from the tank to the plurality of water supply outlets. The ultraviolet sterilization device is provided on the water supply pipe close to at least the water supply outlet for drinking water, includes a light-emitting diode emitting ultraviolet light, and sterilizes water supplied to the water supply outlet by irradiating the water with ultraviolet light from the light-emitting diode.

The present invention concerns a biological reactor used in the field of sanitation for the treatment of sewage and industrial wastewater. The solution proposed in this invention is the coupling of two different treatment processes (anaerobic and aerobic) in the same fixed bed reactor. The invention aims to allow for the construction of plants for the treatment of sewage or very compact industrial effluents, where it is possible to achieve high treatment efficiencies with a small implantation area. In addition, due to the combination of the anaerobic and aerobic processes in fixed beds in the same reactor, the system consumes less energy for aeration and generates a smaller amount of sludge, considerably reducing the operating costs of the treatment plant.

The present disclosure relates to water environment governance technology, and particularly discloses an urban river/lake water environment multi-interface governance and restoration method. The method is a multi-interface coordinated governance and restoration method based on “control for bottom, regulation for middle and governance for top”, including: “control for bottom”—controlling the emission of sediment nutritive salts and the dormancy and recovery of algae; “regulation for middle”—regulating primary productivity in a water body to inhibit the recovery of the algae; and “governance for top”—reducing nitrogen and phosphorus nutrients of an air-water interface to control the reproduction and growth of the algae. In the present disclosure, the water body governance and restoration technology based on interface coordination can effectively inhibit the outbreak of cyanobacteria and avoid extreme conditions in the ecosystem.

A water processing system is provided for processing or conditioning water to be distributed to a downstream function or system. The system includes a water processor with a conditioning element disposed inside a housing between an inlet and outlet of the housing. The conditioning element includes a series of plates having apertures with sharp edges to direct the flow of water and facilitate splitting of small gas bubbles into even smaller nano-bubbles. The plates may have different configurations of apertures. Optionally, a mixer injector introduces a gas, in the form of gas bubbles, into the water flow upstream of the water processor. The injector introduces additional gas volume in the form of relatively large bubbles, which are subsequently split into smaller bubbles (including nano-bubbles) in the water processor.

The invention relates to water regeneration in a fish breeding complex combining closed and flow-through water supply systems. A module of a biological filter in a water regeneration system comprises a reservoir, an aerator, a channel for sludge accumulation and discharge and a reservoir bottom sloped in direction of the water movement and, with the water surface, forming a diffuser providing for circulation of water and filler in the biological filter. Fish breeding complex comprises fish breeding pools and a water regeneration system comprising a mud settler-denitrificator, a device for water lifting and aeration, a biological filter, degassing and disinfection units. Each fish breeding pool comprises water oxygenation and disinfection systems, dosage units, water discharge systems and insoluble residues collecting and discharge systems. In the water flow-through mode, water regeneration system is switched off and water supply from an outside source and wastewater discharge are switched on.

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 and apparatus for conditioning the settled solids in the bottom of a wastewater filtration tank to reduce the acidification of the sludge and prevent the excessive growth of undesirable biological growth.

The present invention discloses a plasma denitrification device, which comprises a plasma generating device and a denitrification reservoir. The plasma generating device comprises a plasma generator and a pulsed power supply. The plasma generator comprises at least one set of an electrode to generate plasma. An inlet of the plasma generator is configured to allow sewage passage. The denitrification reservoir comprises a shell and a denitrification zone, a water purification zone, and a sludge collecting zone provided inside the shell. The present invention effectively reduces total nitrogen and ammonia nitrogen in the polluted water body and helps to reduce COD, BOD, total phosphorus and chroma of the water body. The dissolved oxygen level of the water body is also increased after the purification process.
