Exemplary embodiments are also directed to the check valve and the roller latch themselves. Exemplary embodiments are directed to a filter medium for pool cleaners that includes embossments providing flow channels for water, and to roller assemblies for pool cleaners. Exemplary embodiments are directed to pool cleaners including alternative pump motor engagements. Exemplary embodiments are directed to pool cleaners power supplies that include a potted and contoured power board assembly, and to kickstands therefor. Exemplary embodiments are directed to a pool cleaner caddy, and removable wheels therefor.

A flow back system for separating solids from a slurry recovered from a hydrocarbon well. The system includes a V-shaped tank with a first series of baffles configured to cause the settling of solids that are moved by a shaftless auger to a conduit fluidly connected to hydrocyclones mounted over a linear shaker. The overflow from the hydrocyclones is discharged through a second conduit back into the tank for processing by a second series of baffles resulting in a clean effluent. The clean effluent is recirculated in the well.

An industrial wastewater and hydrocarbon treatment system including of a plurality of reactors and treatment modules that allows the application of principles of chemistry and quantum physics, dissociating electrons from the atoms or chemical elements contained in the hydrocarbon contaminated water. This invention advantageously allows the separation of water and oil in an efficient way, through the use of electromagnetic pulses with low amperage, and a series of filters.

The invention in at least one embodiment includes a system for treating water having an intake module, a vortex module, a disk-pack module, and a motor module where the intake module is above the vortex module, which is above the disk-pack module and the motor module. In a further embodiment, a housing is provided over at least the intake module and the vortex module and sits above the disk-pack module. In at least one further embodiment, the disk-pack module includes a disk-pack turbine having a plurality of disks having at least one waveform present on at least one of the disks.

A dissolved air floatation apparatus including an ultrafine bubble-containing liquid production device and a dissolved air floatation tank. The ultrafine bubble-containing liquid production device includes a gas-liquid mixing unit and a bubble-containing liquid separation device. The bubble-containing liquid separation device swirls a liquid containing ultrafine bubbles and larger bubbles in a storage tank to concentrate the liquid that contains the ultrafine bubbles and the liquid that contains the larger bubbles to a central part of the swirling flow followed by discharge. A pressurized ultrafine bubble-containing liquid is mixed in a raw liquid containing a subject to be cleansed and is poured into the dissolved air floatation tank to cause a suspended substance and a dissolved component in the raw liquid to be adsorbed on an interface of fine bubbles and be floated in the dissolved air floatation tank to be extracted.

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.

The invention in at least one embodiment includes a system for treating water having an intake module, a vortex module, a disk-pack module, and a motor module. In at least one embodiment, a water system includes vortex housing having an interior wall defining a vortex chamber in fluid communication with the expansion chamber of said disk-pack turbine and inlets into the vortex chamber, and the vortex chamber having an upper section with a bowl or modified concave hyperbolic shape into which fluid is received from said inlets and a lower section with a conical or funnel shape with a steep vertical angle of change that opens into expansion chamber. In at least one further embodiment, the disk-pack module includes a disk-pack turbine having a plurality of disks having at least one waveform present on at least one of the disks.

The present invention relates to the process of purification of boric acid by ion exchange method. Boric acid is dissolved in hot demineralized water. The hot solution is pressure-filtered. The hot saturated solution, which is purified from water-insoluble, is passed through a column containing strong cation exchange resin, followed by a column containing weak anion exchange resin at the same temperature and cooled afterwards. The crystals settling by cooling are separated from the mother liquor, the amount of aqueous solution within them is reduced and then dried. The waste solution formed during crystallization and filtrate formed after separation of crystals from aqueous solution are mixed and used in boric acid dissolving process. The developed method enables the reduction of sodium, sulfate, chloride and iron impurities of technical grade boric acid to less than 1 ppm and is more economic and environmental friendly than current methods.
