Disclosed are remote oily water treatment systems, including systems and related methods of remote oily water treatment with point-of-treatment discharge of treated water. In a preferred embodiment, (a) oily water is treated at a location proximate to where the oily water by passing the oily water through a tank containing a medium defined by at least one polymer mixed with activated carbon and (b) treated water is discharged at the point-of-treatment of the oily water.

The present invention relates generally to the field of emission control equipment for boilers, heaters, kilns, or other flue gas-, or combustion gas-, generating devices (e.g., those located at power plants, processing plants, etc.) and, in particular to a new and useful method and apparatus for reducing and/or eliminating various liquid discharges from one or more emission control equipment devices (e.g., one or more wet flue gas desulfurization (WFGD) units). In another embodiment, the method and apparatus of the present invention is designed to reduce and/or eliminate the amount of liquid waste that is discharged from a WFGD unit by subjecting the WFGD liquid waste to one or more drying processes, one or more spray dryer (or spray dry) absorber processes, and/or one or more spray dryer (or spray dry) evaporation processes.

Sludge dewatering process assisted by flocculating reactant, said process comprising an injection of flocculating reactant into the sludge and a step of dewatering said sludge, characterized in that it comprises a preliminary step that consists in mixing said sludge in a mixer (4) comprising a cylindrical chamber (4a) equipped with blades (4c) rotatably mounted on a shaft (4b) rotating at a speed of rotation of between 500 rpm and 4000 rpm, so as to destructure the sludge and reduce the viscosity thereof, and in discharging the sludge from said mixer (4) via a network (11) to said dewatering step, and in that it comprises a step of depressurizing said mixer (4) and said network giving rise to the lysis, by cavitation, of said sludge, said depressurizing step being carried out over a period of at least 0.1 second. Corresponding plant.

A method for modifying a wastewater treatment device, the method including: 1) fixing a filling support in a wastewater pool, where the filling support includes a support frame; the support frame includes a hollow shaft, a fixed ring, and at least one vane; 2) adjusting the height of the filling support, until the fixed ring is submerged below the liquid level of the wastewater pool, where the water intake velocity of the wastewater pool is no less than 0.25 m/s, whereby a water current is produced and drives the support frame to rotate; 3) adding a functional liquid into the hollow shaft; and 4) adding an enzyme mixture to the hollow shaft when the rotation speed of the support frame is less than a first preset value, until the rotation speed of the support frame reaches a second preset value.

The present invention provides a method and an apparatus for treating sewage sludge, the method comprising applying a plurality of ultrafine bubbles to a sludge to form an at least partially aerated sludge, applying acoustic energy to the aerated sludge to agitate at least a portion of the ultrafine bubbles and applying an electric field to the aerated sludge to impart an electrophoretic mobility to the ultrafine bubbles to thereby facilitate separation and transport of water molecules from solid matter within the sludge.

For sewage sludge reduction, an apparatus includes a front-end auxiliary filter plate, a back-end auxiliary filter plate, and a plurality of filter plate modules disposed between the front-end auxiliary filter plate and the back-end auxiliary filter plate. Each filter plate module includes a middle main filter plate, a middle auxiliary filter plate, and a plurality of electromagnetic modules comprising an electromagnetic coil wound around an electromagnetic core. The middle main filter plate and the middle auxiliary filter plate are disposed at opposite sides of the electromagnetic modules. A plurality of microwave generators send microwaves through microwave acting channels to irradiate the sewage sludge. An electric current is applied to the electromagnetic coil, attracting the middle auxiliary filter plates and the main filter plates and applying pressure to the sewage sludge.

Certain exemplary aspects of the present disclosure are directed towards an apparatus for electrostatic fluid filtration. The apparatus utilizing alternating positive and negative electrodes in conjunction with filter media there between to filter contaminants from a fluid flow.

The invention relates to a method and an assembly for recovering magnesium ammonium phosphate from slurry that is supplied to a reaction container (10) in which an aerobic milieu is present and in which the slurry is guided in a circuit with the aid of ventilation. Cationic magnesium, such as magnesium chloride, is added to the slurry, and magnesium ammonium phosphate crystals which are precipitated from the slurry are removed via a removal device (30) provided in the base region of the reaction container. Substances which contain magnesium ammonium phosphate crystals collected in the removal device (30) are loosened and/or rinsed.

A method for treating a water-containing substance, including: mixing a water-containing substance with a solvent at a first temperature to obtain a mixture containing a solid substance and a liquid substance; conducting a first separation treatment of the mixture to obtain the solid substance and the liquid substance; and conducting a second separation treatment of the liquid substance obtained by the first separation treatment at a second temperature to obtain an aqueous phase and an organic phase, the organic phase contains the solvent. The mutual solubility of the solvent and water at the first temperature is higher than that of the solvent and water at the second temperature, so that the separation and recovery of water is achieved by liquid-liquid separation without phase transition in the method for treating a water-containing substance, so the energy consumption can be effectively reduced. The invention further relates to a corresponding device.

An organic wastewater treatment apparatus biologically treats organic wastewater containing nitrogen using a treatment tank storing activated sludge. A top-bottom partition member divides the treatment tank in into an upper space and a lower space. A plurality of anoxic tanks are formed in the lower space, while a plurality of aerobic tanks, each of which having an immersion-type membrane separation device, are formed in the upper space. A raw water supply path divides and supplies the organic wastewater to each anoxic tank. A plurality of denitrifying liquid transfer paths repeatedly transfers the activated sludge from the anoxic tanks to the aerobic tanks, while a plurality of nitrifying liquid transfer paths repeatedly transfer the activated sludge from the aerobic tanks to the anoxic tanks, whereby the activated sludge is circulated throughout the treatment tank.
