A machine and methods using electro-chemical treatments, sedimentation processes and dissolved air flotation technologies for clarification of several kind of wastewater produced in industries, sewages, ponds, lakes, canals etc. The machine comprises of, feeding lines with multiple feeding point, a tank and further a collection tank. The wastewater is passed into the feeding line which may comprises of several feeding points for coagulants, flocculants, and other chemicals dosing into the flow of wastewater and may also comprises of a static mixer for mixing the coagulants, flocculants, and other chemicals with wastewater to agglomerate any solid particles and to accelerate separation of the solid particles in the tank. Once the solid are formed, they can go up or down, therefore to remove the suspended solids the outlet are rearranged depending on the suspended solids. Further, the machine is used for treatment of wastewater utilising multi pass concept to produce clean water.

The present disclosure relates to the technical field of waste water treatment, and provides a device and a method for controlling diffusion of MPs (Microplastics) carried with ARGs (Antibiotic Resistance Genes) in a waste water treatment system. The device includes a water collection tank arranged on a mounting rack, a collection assembly arranged inside the water collection tank and used for collecting MPs carried with ARGs in waste water, and a treatment assembly arranged inside the water collection tank and used for removing the collected MPs carried with ARGs in waste water. According to the method, sorting treatment for the MPs carried with ARGs in waste water is realized effectively with an air flotation principle and an electric separation principle. The device is simple in integral structure, and has the advantage of convenience in mounting.

A portable unit and associated processing are described for clarifying process water used in oil and gas operations such as fracking or drill-out operations. In the portable unit, dirty water (402) is introduced into a clarifier (400). The dirty water (402) is directed to a bottom of the clarifier (400) where dissolved air 408 from a dissolved air flotation pump (410) is injected into the water (402). The water (402) then passes across the inclined plates (412). Particles are separated from the water (402) via interaction with the plates (412) and directed to collectors (414), at the bottom of the clarifier (404), by gravitation. In addition, a floc, enhanced by the injection of the dissolved air (408), is skimmed from the water surface. The result of this process flow is clarified water (430) that can be returned to the frack and post-frack completion process.

A mechanical separator for separating a fluid sample into first and second phases is disclosed. The mechanical separator includes a float having a first portion and a second portion, a ballast circumferentially disposed about a section of the float, and a deformable bellows defining an open passageway extending between a first end and a second end. The ballast is longitudinally moveable with respect to the float and engaged with the deformable bellows between the first end and the second end. At least a portion of the float is transitionable from a restraint position to a sealed position through the first end of the bellows. The first portion of the float can be positioned within the interior of the deformable bellows in the restraint position, and the first portion of the float can be positioned at an exterior location longitudinally displaced from the deformable bellows in the sealed position.

This disclosure relates to an apparatus and method for analyzing an influence variable on membrane fouling of a seawater desalination system, wherein influence variables other than variables having a low degree of influence, among variables affecting the membrane, are selected, and the influence thereof on membrane fouling is used to derive an equation. The apparatus includes a variable storage unit configured to store variables affecting membrane fouling of a seawater desalination system, a dominant variable selection unit configured to select at least one dominant variable among the variables through at least one algorithm, and an equation derivation unit configured to derive a specific equation based on a correlation between the selected dominant variable and the membrane fouling.

Treating an organic effluent is disclosed. The effluent is fed in a continuous flow at a rate q via a first chamber maintained at a first pressure and/or directly through a first narrowing to a second chamber or container maintained at a second medium pressure by the injection of air into the second chamber at a rate Q in order to obtain an emulsion in the second chamber. A head loss is generated in the emulsion optionally modified by a second and/or third narrowing or a feed valve for a third chamber maintained at a third pressure in the region immediately downstream of the second or third narrowing and/or valve. A flocculant is injected into the region of the third chamber. The emulsion at atmospheric pressure then being degasified and the emulsion thus degasified being recovered in a filtration or decanting device.

A method for treating produced water from a fracking operation is disclosed. The produced water is first fed to a compact separator for the removal of suspended materials. This produced water is then treated for dissolved gases and suspended oils before being fed to a crystallizer where salts are separated from the produced water thereby producing fresh water for reuse or other means. Alternatively, the produced water may be fed to a disinfection system and a concentrator depending upon the composition of the produced water.

The present disclosure provides devices and systems that utilize concurrent and countercurrent exchange platforms to produce purified silicon.

Disclosed are a method for recycling an iron ore tailing and use thereof. The method includes: 1) conditioning the iron ore tailing to obtain a first slurry, adding water glass and a sodium oleate-associated substance sequentially to the first slurry to obtain a first mixture, and subjecting the first mixture to first flotation to obtain a mixed flotation foam product and a mixed flotation grit; 2) filtering the mixed flotation foam product to obtain a solid, drying, roasting at 400 C. to 650 C., and grinding to obtain a ground product; and 3) conditioning the ground product to obtain a second slurry, adding sodium sulfide, water glass, sodium alginate, hydroxamic acid, and terpenic oil sequentially to the second slurry to obtain a second mixture, and subjecting the second mixture to second flotation to obtain a rare earth concentrate and a rare earth tailing.
