This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by applying non-condensable media to create density differences and then using a mechanical device to separate the solids from the liquids based on the density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.

The lube oil inlet and the hot air inlet are configured to introduce and contact the water contaminated lube oil and the hot air in the contact zone, producing a dehydrated oil received into the decontaminated oil collection zone and a wet air stream containing entrained oil droplets received into the disengagement zone. The disengagement zone includes a tortuous divergent flow path traversing from a disengagement zone inlet to the wet air outlet.

Provide is a phase separator having a phase separation function and a function of promoting mutual contact between the first liquid and the second liquid in a compact structure. The phase separator includes a main body container, a partition member, and a mixed-liquid introduction part. The body container defines a storage space for the mixed liquid. The partition member partitions the storage space into a plurality of horizontally arranged spaces including a mutual contact space allowing the first and second liquids to flow vertically while being in contact with each other, and a phase separation space for separating the mixed liquid into a first liquid phase and a second liquid phase. The mixed-liquid introduction part allows introduction of the mixed liquid through the mixed-liquid introduction part to make the mixed liquid flow from the introduction end toward the discharge end of the partition member through the mutual contact space.

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.
