A system for treating an effluent stream from a food production facility may include a first reactor unit including a first reactor tank and an electrical treatment reactor that is fluidly connected to the first reactor tank. When the reactor assembly is in use the effluent may travel along a reactor circulation flow path in which effluent is drawn from the first tank, flows through the electrical treatment reactor and is subjected to an electrical charge and then returns to the first tank, whereby a reaction initiated in the effluent by the electrical charge within the electrical treatment reactor continues when the effluent is returned to the first tank. A second processing unit may be downstream from the first reactor unit to receive the partially treated effluent stream and configured to further process the partially treated effluent.

Provided are a water quality purification device, and a water purifier and an aquarium that use the water quality purification device. The water quality purification device includes a component filled with a micro-electrolysis catalyst and a biological filtration component that are connected in series. By utilizing a micro-electrolysis technology, pollutants in water are preprocessed and the biodegradability of the water is improved. A water body processed by the micro-electrolysis catalyst enters the biological filtration component, which can greatly improve the purification efficiency of the biological filter bed. Working together with an adsorption electrode, this structure can effectively stabilize the water quality in the aquarium and greatly reduce the required times of changing water.

Methods and systems are provided for producing ionized alkaline solutions (e.g. ionized alkaline water) that exhibit long-term stability when stored at room temperature.

A method of treating an aqueous composition includes immersing a galvanic cell in the aqueous composition to form a treated aqueous composition. The galvanic cell includes an anode including Mg, Al, Fe, Zn, or a combination thereof. The galvanic cell includes a cathode having a different composition than the anode, the cathode including Cu, Ni, Fe, or a combination thereof.

Sintered Wave Multi-Media Polarity Conversion Treatment Apparatus and Process is disclosed, which uses a non-destructive physiochemical PFAS vapor emissions treatment system to provide vacuum and vapor conveyance for 1) a Polarity Conversion Unit for non-destructive PFAS removal from soil, sludges, rechargeable galvanic filter media and objects, 2) a fluids treatment line for PFAS removal from water, brines, foams and colloids, and 3) an amphiphilic decontamination wand for PFAS removal from hard surfaces. The vapor emissions treatment system uses direct spray cooling to cool treatment gases where fluid chemistry causes pre-micellular aggregates/liquids crystals formation. Filtered aggregates are dried in a Brine Pot Evaporator for off-site disposal. Residual PFAS vapors are removed through a Vapor Phase Galvanic Separator where galvanic currents offer high energy interfaces of varying charges for monomeric PFAS self-assembly. The Polarity Conversion Unit assembly uses transportable flow through vessels, static geometry, high surface area, treatment gas temperature and velocity modulation to reduce thermal resistivity of the media. Treatment gas is sequentially routed around shaped vertical media beds where thermal energy disorganizes surface polarities (Gibbs free energy) disconnecting amphiphilic compounds/mixtures from the media. The fluids treatment line uses a Surface Excess Concentrator where a surface excess complex is created, removed and dried for off-site disposal. Treated bulk fluids exit from the bottom (below the surface) and are routed to the Aqueous Phase Galvanic Separator. Galvanic filter media is recharged in the Polarity Conversion Unit for reuse. Hard surfaces are decontaminated using the amphiphilic decontamination wand to disorganize surface polarity. Catalytic oxidation and granular activated carbon systems are also used to capture, destroy and measure classic contaminants and cleaved hydrocarbons from fluorinated precursors during treatment.

For bio-electrically generating electric power from organic ingredients of a waste water flowing in a flow direction, an anode is immersed in the waste water in a first spatial area, and oxygen is supplied to a cathode which is electrically connected to the anode and arranged in a second spatial area delimited from the first spatial area by means of a proton-permeable membrane. A voltage between the anode and the cathode is increased by a DC/DC converter located at the anode and the cathode, and a further voltage between a further anode in said or a further first spatial area and a further cathode in said or a further second spatial area is increased by a further DC/DC converter located at the further anode and the further cathode. A DC voltage link is charged with the DC/DC converter and the further DC/DC converter connected in parallel to the DC voltage link.

The present invention discloses a filter material for a culture system, and a preparation method and use thereof. The filter material comprises an anode material and a cathode material, wherein the anode material is an active metal, and the cathode material is an inactive metal or a conductive non-metal. The filter material can significantly improve the water quality in the culture system, be used for in-situ treatment of the water body in the culture system and be convenient to use. The filter material does not require additional application of voltage or current, and thus is safer. At the same time, the filter material has a long service life and does not need to be changed frequently. In addition, the preparation method of the filter material is simple, efficient, and environmentally friendly, and is advantageous for large-scale production.
