A novel reaction portion reduces particle formation in fluids during treatment, thereby improving the defect of particle accumulation in a reaction portion. Also, the system includes the device, wherein a modular design enables the system to have the advantage of easy repair and maintenance.

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.

A method and apparatus for extracting botanical oil from botanical mass includes milling the biomass and chilling the milled biomass. The biomass is then exposed to a chilled ethanol solvent. Water is added and the solution introduced into a first centrifuge. The clean ethanol slurry is then introduced into an evaporator leaving a two-phase mixture which is introduced into a second centrifuge which separates the water from the pure botanical oil.

Provided is a humidity control device capable of stably absorbing and desorbing moisture. The humidity control device includes: a moisture absorber causing a hygroscopic material to come into contact with air so that the hygroscopic material absorbs portion of moisture contained in the air, the hygroscopic material being in liquid and containing water, polyalcohol having hygroscopicity, and metal salt having hygroscopicity; and a composition controller controlling composition of the hygroscopic material. The composition controller controls the composition of the hygroscopic material to be within a range in which the hygroscopic material is capable of absorbing the moisture while the metal salt is kept from being deposited.

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.

A method of treating a liquid by creating nanobubbles of a desired gas within a target liquid and allowing the desired gas to react with a target component of the target liquid. The desired gas can be selected to be reactive with the target component, and a desired liquid can be formed after the desired gas reacts with the target component.

A frac sand separator system includes a sand separator having an inlet fluidly connected to a well for receiving a fracking return mixture from the well. The sand separator is configured to separate water of the fracking return mixture from particulate matter of the fracking return mixture. The sand separator includes an outlet. The frac sand separator system includes a collection container fluidly connected to the outlet of the sand separator for receiving the particulate matter from the sand separator. At least one outlet valve is fluidly connected between the outlet of the sand separator and the collection container. The frac sand separator system includes a computing device operatively connected to the at least one outlet valve. The computing device includes a processor configured to automatically open the at least one outlet valve such that the particulate matter is released from the sand separator into the collection container.

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 filter is provided including a vessel having an input positioned near the top of the vessel for contaminated fluid; the vessel containing media; a drain screen; a propeller rotatable on a drive shaft extending downwardly from the top of the vessel; a deflector plate below the drain screen to impel media outwardly from the center of the vessel; a plurality of baffles positioned on side walls of the vessel; and a drain to remove fluid from the vessel.

A method for water purification utilizing a cylindrical vessel containing a hydrocyclone nest. The heated contaminated water is fed into the nest, which includes a first set of hydrocyclones, at least one intermediate set of hydrocyclones, and a final set of hydrocyclones, the hydrocyclones in each set arranged in parallel, and each set arranged in series. The heated contaminated water is pumped into the cylindrical vessel such that the heated contaminated water enters a tangential inlet of each of the hydrocyclones, the hydrocyclones separate the heated contaminated water into steam and solids/concentrate, the steam exits through an overflow of the hydrocyclones and a first outlet of the cylindrical vessel, the solids/concentrate exit through an underflow of the hydrocyclones and into the subsequent set of hydrocyclones until the final set of hydrocyclones, and then out through a second outlet of the cylindrical vessel. The steam is condensed into purified water.
