The present disclosure discloses a method and device for removing Organic Micropollutants (OMPs) in water, and belongs to the technical field of wastewater treatment. The method includes the following steps: S1: aerating residual sludge under a starvation condition to enrich starved-state microorganisms; and S2: treating wastewater containing OMPs under an aeration condition with sludge containing the starved-state microorganisms obtained in step S1, and periodically updating the sludge containing the starved-state microorganisms. According to the present disclosure, aerobic starvation treatment is performed on the sludge to gradually reduce the abundance of microorganisms that may use degradable organic matters only and enrich microorganisms that may use complex organic matters in the sludge, and the enriched sludge may degrade various OMPs and be used to remove OMPs in wastewater. The process is easy to operate and low in cost and has relatively high practical application value.

A modular liquid waste treatment system is disclosed. In accordance with some embodiments, the system includes a central distribution unit and one or more treatment fins in flow communication therewith. The distribution unit may be configured to receive liquid waste from a given source and distribute that waste, at least in part, to one or more treatment fins. In turn, bacteria present in a given treatment fin treat the liquid waste, and the resultant treated liquid may drain from the fin to the surrounding environment. In some embodiments, a given treatment fin may include porous media providing a large surface area on which bacteria may grow to facilitate treatment. The system may be installed in and/or above the ground, and in some cases may be surrounded, at least in part, with treatment sand and/or other treatment media. The system may be used in aerobic and/or anaerobic processing of liquid waste.

A saturated layer stormwater filtering system with down-flow layered multimedia filters is disclosed. The filtering system may include an upflow pretreatment chamber and a subsequent filtration chamber. It also includes a snorkel pipe as an adjustable head control or internal baffles. The system incorporates gravity powered partially saturated stormwater media filters to harness the potential energy of stormwater from downspouts and pumped flows from stormwater catchments to drive the polluted stormwater in a hydraulically controlled fashion by gravity through a series of filter media layers.

An inlet arrangement for a tray-based grit removal system utilizes a set of separate inlet hoses to connect the vertical stack of trays to a horizontally-disposed inlet chute, thus eliminating the inlet duct utilized in prior art configurations. Each hose is configured to have about the same length and diameter, providing an essentially uniform influent pressure at the input to each tray. The hoses are directly connected between the trays and the inlet chute, where each tray may be formed to include a hose coupler of the same diameter as the hose. The inlet chute may take the form of a trough or tube (or other suitable geometry), with the plurality of hoses all terminating along a common, horizontal output face of the chute.

The present invention comprises a process and apparatus for separation of hydrocarbons from hydrocarbon-containing produced water, wherein in stage 1 the hydrocarbon-containing produced water is supplied with a gas-containing component, whereupon a gas- and hydrocarbon-containing produced water mixture is fed to an inlet tube (22, 27) in the center of a tank, whereupon the said mixture is tangentially distributed via at least one nozzle (7) and at least one baffle plate (8.1), whereupon separated hydrocarbons are conveyed to at least one outlet from the tank and cleaned water is conveyed to an outlet (12) from the tank.

The disclosure relates to a system for separating waste. The waste separating system includes a compacting assembly, a liquid diverting assembly, and a controller configured to control aspects of the compacting assembly and the liquid diverting assembly. The waste separating system can divert waste liquid from a manufacturing assembly to a liquid diverting assembly, where a controller is configured to selectively control a flow of the waste liquid to a drain or to a storage tank.

A water purification system comprising a salvage pump, a vacuum assembly, and a clean water assembly. The salvage pump is configured to draw water from a water source. The vacuum assembly is configured to remove solutes from the water via vacuum evaporation. The clean water assembly is configured to remove non-soluble particles and/or bacteria from the water.

A hydrocarbon emulsion treatment system includes a treatment tank having a gas vent for operating the treatment tank near atmospheric pressure. The treatment tank separates water and oil in the emulsion for discharge to separate water and oil tanks respectively. According to a preferred embodiment, the treatment tank and the oil tank are supported on a common frame including an integral secondary containment structure providing secondary containment to both the treatment tank and the oil tank. The treatment tank is supported at greater elevation than the oil tank to allow the flow of oil from the treatment tank to the oil tank primarily under force of gravity.

Provided are an apparatus and a method for biological treatment of an organic wastewater where it is possible to efficiently remove organic matter under high load while reducing the amount of air used for aerobic biological treatment and substantially decreasing the amount of sludge generated. The apparatus is provided with: a first biological treatment tank which has a fixed-type immobilized biocarrier and an aeration means; a second biological treatment tank to which a treated liquid from the first tank is introduced so as to perform treatment using suspended microorganisms, and which has an aeration means; and a sedimentation tank in which solid-liquid from the second tank is separated said liquid into settled sludge and treated water, wherein the apparatus has an influent line through which an organic wastewater is introduced to the first tank and the second tank, and a return line through which part of settled sludge discharged from the tank is returned to the tank.

A flow guide mesh has a water inlet side and a water outlet side opposite to each other, wherein a first water isolating material is provided on the water inlet side of the flow guide mesh to seal a part of the water inlet side, and an effective water inlet width is defined on the water inlet side, a second water isolating material is provided on the water outlet side of the flow guide mesh to seal a part of the water outlet side, and an effective water outlet width is defined on the water outlet side. In addition, the flow guide mesh has a comb-like structure comprising at least one comb tooth within the effective water outlet width of the water outlet side. Also disclosed are a membrane element and a filter assembly.
