A flocculant for treating a processing waste liquid is provided, in which processing debris generated by processing are mixed in pure water supplied at a time of processing by a processing apparatus, into fresh water, and the flocculant is formed by pulverizing an ion exchange resin for purifying fresh water into pure water to a size of 100 μm or below.

A combined device for sewage deep treatment integrally consists of an open box body (1) divided into multiple water treatment units (29) by a partition wall (27). Each water treatment unit (29) is divided into multiple grids by a partition wall (27′). The lower part of the box body (1) is provided with a conical structure (30) having a discharging door (22) thereunder. The partition wall (27) of the box body (1) has a water blocking belt (33) in the middle thereof, and the box body (1) has rails (31) mounted on two sides of the top thereof, rails (31) having an electric operating platform (2) mounted thereon. The box body (1) is filled with water processing granular carbon (32). Also disclosed is a sewage treatment method employing the combined sewage deep-treatment device. With the method, it is convenient to replace activated carbon, thereby solving the problem that it is difficult for the sewage treatment system to operate continuously and stably when replacing the activated carbon in traditional activated carbon filter.

In at least one embodiment, the invention provides a retrofit for existing water treatment systems where the retrofit includes at least one of the following: a particulate separator, a supplementary inlet, and a waveform disk-pack turbine. In a further embodiment, the invention includes a water treatment system combined with at least one of the following: a particulate separator, a supplementary inlet, and a waveform disk-pack turbine.

A wastewater concentrator a liquid evaporator assembly, a gas-liquid separator, an exhaust assembly, and a flowback water concentrating system. The flowback water concentrating system includes a settling tank fluidly connected to the gas-liquid separator and a supernatant liquid concentration sensor for measuring a concentration of dissolved solids in the supernatant liquid in the settling tank.

The present disclosure is drawn to evaporation panel assemblies, systems, and methods. For example, a modular evaporation panel system can include a plurality of evaporation panels with individual evaporation panels including evaporation shelves that are laterally elongated, vertically stacked, and spaced apart; vertical support columns positioned along the evaporation shelves to vertically support and separate the evaporation shelves; female-receiving openings defined by multiple evaporation shelves and multiple support columns; and male connectors positioned at lateral ends of the evaporation panels. The male connectors can be releasably receivable by the female-receiving openings of an adjacent evaporation panel, thereby providing modular assembly and disassembly of multiple evaporation panels relative to one another.

The present invention is directed to a clarifier for water treatment including a module. The module includes a planar inclined sheet; a plurality of vertically-oriented supports; and a tensioner. The at least one planar inclined sheet is tensioned between the plurality of vertically-oriented supports and the tensioner is configured to bring the planar inclined sheet to an even centerline.

The invention relates to a rapid flotation device, in particular using dissolved air, for treating water laden with suspended matter (MES). The device comprises a mixing area (B) separated from a flotation area (C) by a wall (n) above which the liquid to be treated passes from the mixing area. The bottom portion of the flotation area comprises: a perforated floor (1) located above an apron (R), a floated-water discharge being provided under the floor and leading to an outlet system (3); and at least two separate channels (2) which are oriented in the direction of flow of the water and are provided under the floor (1), and under optional structures (w) extending from the floor, to a point upstream of the outlet system (3). The downstream end (2.1) of the channels is open and located above the floor level, and a discharge means (V) is provided, for each channel, at the end of the downstream bottom portion of said channel.

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 new wet oxidation process of wastes, specifically of mixtures of at least two, liquid (wastewaters) and dense (sludges), pumpable wastes is described. An apparatus useful for a wet oxidation process of this type is also described.

A source liquid including a solvent with a dissolved impurity flows into a reservoir. The source liquid or a concentration of the source liquid is pumped from the reservoir through a pressure exchanger into an upstream side of a liquid-separation module. The module includes a membrane that at least partially purified solvent as filtrate to a permeate side of the liquid-separation module while diverting the impurity in a feed retentate on the upstream side of the liquid-separation module. The substantially pure water is extracted from the permeate side of the liquid-separation module, while the feed retentate is passed from the upstream side of the liquid-separation module through the pressure exchanger, where pressure from the feed retentate is transferred to the feed from the reservoir. The feed retentate is then passed from the pressure exchanger to the reservoir and recirculated as a component of the feed via the above steps.
