The present invention discloses an oil-contained wastewater treatment apparatus applying the integrative physical methods. The wastewater treatment system of the invention may include a main tank, where the upper part is a rectangular body and the lower part is designed to a multi-bucket bottom structure. Two oil collection boxes are arranged to both outside ends of tank. A mud discharging outlet is attached to the bottom of the tank. Meanwhile, both of a water outlet and an electric polarizer are localized at the end face of the effluent on the tank. A power supply for the electro-adsorber is fixed to the inlet end on the top face of the tank. Divided by upper and lower deflectors, the inside of the tank is divided to three processing units, i.e., sludge-water separation unit, degradation-coalescence treatment unit, and sedimentation-electric polarization unit. Vortex centripetal gas flotation is applied to remove oil. Electro-adsorption induces the micelle clustering to achieve the decolorization. The electric polarization functions as anti-scaling, descaling, sterilization, and corrosion inhibition. Moreover, the referred physical treatment can be fulfilled in virtue of centrifugal force, buoyancy, gravity, adsorption force, coalescence force, inertia, shifting, and modification. Through the application of the system, the oil-contained wastewater can be treated environmentally friendly, safe and pollution-free. Besides the above advantages, high removal efficiency can make the apparatus and method a widely used approach on the oil-contained wastewater treatment.

The present disclosure provides apparatus, systems, and methods for improving slop water treatment efficiency. The method generally includes separating contaminated fluid into a clean fluid layer and one or more contaminant layers floating on a surface of the clean fluid layer in a vessel; reporting to a control unit, a location, sensed by level sensor(s), of an interface between the clean fluid layer and the contaminant layer(s); reporting to the control unit, a height, sensed by a first position sensor, of a skimmer relative to the vessel; adjusting, using the control unit and based on the reported location of the interface and/or the reported height of the skimmer, the height of the skimmer so that one or more components of the skimmer are positioned proximate the sensed location of the interface; and skimming, using the skimmer, the contaminant layer(s) off of the clean fluid layer proximate the sensed interface.

Various systems, apparatus, and methods used to remove solids from water are provided. A plate assembly for a plate settler assembly is provided which includes a plate body with a plate body thickness. The plate assembly also includes a first support plate attached to the plate body on a first axis extending between the first and second end of the plate body. The plate assembly may further include a second support plate attached to the plate body on a second axis extending between the first and second end. The plate assembly may also include a stiffener or a central stiffener attached to the plate body on a third axis. The plate assembly may still further include a flow control plate along the first end. The thickness of the support plates, stiffener, and flow control plate are greater than the plate body thickness. A corresponding method of manufacture is provided.

A shot peening apparatus includes a first tank. The first tank includes a swirl flow generating mechanism and a suction port. The swirl flow generating mechanism swirls a waste liquid in the circumferential direction. The suction port is disposed at the axial center of the first tank. The suction port opens toward a bottom wall and suctions the waste liquid. A plurality of blade members are provided inside the first tank. The plurality of blade members hinders the waste liquid from swirling in the first tank.

A separator fluidly connected to a wellbore includes: a vessel defining an interior chamber; an inlet for delivering fluid produced from a wellbore into the vessel at a first pressure; an outlet through which gas is directed out of the vessel at a pressure substantially equal to the first pressure; at least one liquid/oil level sensor capable of detecting the level of liquid within the interior chamber of the vessel and the level of oil within the interior chamber; two electronically controlled valves in fluid communication with the vessel; and a controller connected to the at least one liquid/oil level sensor and the electronically controlled valves and programmed to, in response to a level of the liquid and a level of oil in the interior chamber of the vessel: open, close, or modulate the electronically controlled valves to regulate the combined flow liquid and oil out of the vessel.

Systems and methods to enhance the removal of inorganic contaminants, including metals, from hydrocarbon feedstocks at a refinery. One or more embodiments of such systems and methods may be used to provide a renewable hydrocarbon feedstock having a reduced amount of metal contaminants. The reduction of metal contaminants in the renewable hydrocarbon feedstock mitigates catalyst fouling and/or deactivation during downstream refinery processing of the renewable hydrocarbon feedstock.

A separation tank for the separation of a mixture of oil, gas, water, and solids obtained from an oil field includes distinct regions vertically located within the tank interior where constituent components of the mixture can collect. The inflowing mixture may be directed to a vertical column extending inside the separation tank and can be introduced to the tank interior through a swirl vane diffuser configured to impart a helical direction to the inflowing mixture that assist separation of the mixture component. To further facilitate separation of oil from the mixture, the separation tank may be operatively associated with an aeration system configured to generate and introduce an aerated liquid to the tank interior. Gas dissolved in the aerated liquid may form microbubbles that can naturally adhere to the oil and solids separate it from the mixture which can improve the quality of the water.

Systems and methods to separate water and remove solids from a pre-treated and unfiltered renewable feedstock at or separate from a refinery. Such systems and methods may be used to provide a reduced-contaminant and reduced-solid renewable feedstock for further refining.
