A water treatment system having a base assembly and a treatment assembly. The treatment assembly of the system may be configured to filter particulates from water. The base assembly may include a UV reactor operable to disinfect water for consumption.

The invention relates to a method for the treatment of wastewater in a biological treatment reactor, comprising the steps of (a) introducing wastewater influent at the bottom part of the reactor while simultaneously decanting treated wastewater effluent at the operational water level in the top part of the reactor, (b) an aeration step and (c) a settling step wherein the biomass is allowed to settle; wherein step (a) is performed under vertical plug flow conditions, wherein during step (a) the equal distribution of the influent wastewater across the distributor pipes and/or the degree of plug-flow in the reactor is monitored, and when a suboptimal distribution or a suboptimal degree of plug-flow is detected the influent distributor system and/or effluent decanter system is cleaned by removing fouling and/or blockage.

The invention also relates to a liquid influent system and to an installation for the use in such method for the treatment of wastewater.

A process performed by a plant for oxidation of a waste stream with oxidizable material is described. In a start-up phase, supercritical water is fed to a supercritical water oxidation reactor, heating the process up to supercritical conditions. In a treatment phase, the waste stream is fed to the reactor for supercritical water oxidation treatment, in which sufficient mass of water under supercritical conditions is present in the reactor to retain supercritical conditions with the newly introduced waste stream. Oxygen is used as oxidant and a stoichiometric quantum is added to the reactor. The energy released from the oxidation reaction substitutes the energy provided by the addition of supercritical water up to a point where the reactor achieves near autothermal conditions with supercritical water providing trim heat requirement. The reactor outlet is quench cooled, neutralised and energy is recovered from it. A gas liquid separator ensures that the effluent stream is degassed.

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.

The present disclosure relates to a deep purification device and method for methanol-to-olefin washing water. Provided is a deep purification device for methanol-to-olefin washing water, comprising: a quench tower (1-1), a water washing tower (1-2) connected to an outlet at the top of the quench tower (1-1), a boiling bed separator (1-3) having the top thereof connected to the bottom of the water washing tower (1-2), a fiber coalescer (1-4) connected to the bottom of the boiling bed separator (1-3), and a buffer settling tank (1-5) connected to the sidewall of the boiling bed separator (1-3) at a position near the top. Further provided is a deep purification method for methanol-to-olefin washing water.

A purified water supply pipeline system is provided. Source water flows from a source water inlet to a front filtration module, an inlet solenoid valve, a booster pump, and a fine filtration module and is separated into purified water and waste water. The purified water flows through a first one-way valve to a rear filtration module and then flows to a purified water pipeline, on which a water outlet faucet is mounted. The waste water flows to a waste water pipeline, on which a waste water throttling element and a waste water outlet are disposed. The purified water also reflows to the fine filtration module through a switch solenoid valve and the booster pump, to form a reflow pipeline. The purified water supply pipeline system balances concentration difference on both sides of the fine filtration module. Accordingly, quality of the purified water and user experience are improved.

A fluid treatment system and method of aligning and securing mechanical components within the system. The system comprises a container base with vertically extending sidewalls forming a sump, and a tank retainer disposed on the base within the sump. A system plate encapsulates the sump, and may include a bridge member projecting from the plate's top surface. A media bottle's bottom surface is placed within the tank retainer, and the media bottle's neck is received by an annular collar of the system plate such that the media bottle is secured within the system and movement of the media bottle within the sump is inhibited and/or restricted.

A water processor is provided for processing or conditioning water to be distributed downstream of the water processor. The water processor includes a housing having an inlet and an outlet opposite the inlet. The water processor includes a conditioning element disposed inside of the housing between the inlet and outlet. The conditioning element includes a plurality 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 plurality of plates include a first plate having a first configuration of apertures and a second plate having a second configuration of apertures. The first and second plates are disposed in alternating spaced arrangement along the longitudinal axis of the housing. The second configuration is different from the first configuration such that the flow path through the water processor is circuitous or substantially indirect.
