Abstract: A method of regenerating an ion exchanger which is used to treat a solution introduced to the ion exchanger in a downward charging direction. The ion exchanger includes a non-constrained ion exchange bed of ion exchange material in the form of ion exchange granules or beads and has a concentration profile through the ion exchange material after the solution has been introduced to the ion exchanger in the charging direction. The method of one embodiment includes passing a pre-regenerating solution downwardly through the non-constrained ion exchange bed of ion exchange material in an intermittent pulsed flow of a pulse or downflow of pre-regenerating solution and a subsequent non-flow pause time, followed by passing a regenerating solution upwardly through the non-constrained ion exchange bed of ion exchange material in an intermittent pulsed flow of a pulse or up flow of regenerating solution and a subsequent non-flow pause time, followed by a downflow pulse.

Abstract: An apparatus is provided for improving sand storage at a well site, and a system and method are provided for using the apparatus. The apparatus, which may be referred to as a portable tunnel structure, include a hopper having a perimeter edge and surfaces that are sloped downward and inward to a plurality of hopper outlets, a conveyor system having a conveyor belt disposed below the plurality of hopper outlets, and a support framework including a horizontal base structure for supporting the support framework on a load bearing stratum, horizontal hopper reinforcement beams secured along the outer perimeter edge of the hopper, and outer vertical support beams extending between the horizontal base structure and the horizontal beams.

Abstract: A combined water aeration and filtration unit (WAFU), having a tank with a vent section at a top of said WAFU and above an aeration section above a filtration section at a bottom of said WAFU. The vent section has one or more demisters and one or more vents for detraining water and providing a dry air exit from said WAFU. The air section has a water inlet ending in a spray nozzle near the top of the aeration section to turn incoming dirty water into water droplets and a forced air blower on a side or top of the aeration section for blowing air through said water droplets in rate sufficient to remove volatile organic compounds and precipitate manganese and iron. The aeration section also has one or more annular rings or partially annular baffles on an inside wall of the tank to force water from said inside wall into an interior of the tank. Thus, no water escapes aeration.

Abstract: A modular particulate storage system includes a plurality of portable skids, wherein each skid includes an elongate rectangular base supporting a floor section and a wall section extending upward from the floor section. The plurality of portable skids are securable together in a side-by-side configuration to form a storage bay having a contiguous rectangular floor that combines the floor sections of the plurality of portable skids and a contiguous wall that combines the walls sections of the plurality of portion skids and extends along three sides of the contiguous rectangular floor. One side of the contiguous rectangular floor includes an open passageway into the storage bay. A skid may be formed as a trailer that may be lowered to be supported by the ground.

Abstract: A system and method for projecting a still shot or video projection into a body of water is described herein.

Abstract: A water delivery pipe made from PVC or PVCO and having an inner surface which is rifled. The inner surface of the pipe preferably includes a graphene material. The pipe has improved anti-bacterial properties such that the formation of bacterial biofilms is eliminated or reduced. Methods of making the pipe are also disclosed.

Abstract: A water display including a number of pixels or manifolds that may include water nozzles to emit streams of water and/or other utilities such as lighting is described. The water streams may be pixelated so as to provide a high resolution waveform or other choreography. The choreography transitions between waveforms to provide the appearance of a cascading or undulating wave. A tool to design the water display and simulate its appearance is also described.

Abstract: A device to move and control a water shooter is described. The device may contain features that allow the device to travel along the surface of a reservoir with a water shooter attached. The device may be free from a physical connection to the bottom or the sides of the reservoir so that unique water effects may be achieved.

Abstract: An electrode for electrocoagulation, a method of obtaining it, and an electrocoagulation method using the electrode. Wherein, the electrode allows reducing energy consumption kWh/kg due to the fact that it has a reduced grain size obtained through a heat treatment that gives it the characteristic sought for the reduction in energy consumption.

Abstract: A packed bed catalyst in a pressurized vessel/reactor during contact with a dioxide species precursor enhances catalytic conversion of the precursor to the dioxide species, compared with the same catalytic conversion performed in a non-pressurized vessel/reactor.
