Abstract:
A liquid concentrator having an evaporator assembly and a cyclonic separator includes features designed to improve the performance of the liquid concentrator. A settling chamber is separated from a sump of the cyclonic separator. A liquid inlet opening into a mixing chamber of the evaporator injects wastewater at low pressures. Features to aid in the cleaning of the liquid concentrator include easy open doors and clean water injection ports for cleaning interior portions of the liquid concentrator.
Abstract:
Disclosed herein is an improved pool cleaning vehicle. The vehicle includes a housing, a bottom frame and a filter bag between the housing the bottom frame and attached to the bottom frame. The vehicle includes an intake system for causing water to enter the vehicle housing and to trap dirt and debris in the filter bag. The intake system includes more than one intake, which are typically mounted front and aft of the vehicle. The vehicle includes an outlet for flowing water passing through the filter bag back into the pool. Of course, both of the intake and outlet ports are in communication with the filter bag. The housing typically includes a bottom frame. Both the housing and the bottom frame have side openings defining vents, which serve as side intake ports. In an exemplary embodiment, the intake ports include a duct attached thereto. The duct has an open duct intake. In another exemplary embodiment, the front and/or aft intake port include a duct.
Abstract:
A mobile system for generating and dispensing a chemical includes a portable platform comprising a source of a gaseous chemical, the gaseous chemical forming a solution in water, and a fluid coupling through which the gaseous chemical is delivered to a body of water.
Abstract:
A process for concentrating wastewater includes combining heated gas and liquid wastewater to form a mixture of heated gas and entrained liquid wastewater, breaking the entrained liquid wastewater into fine entrained liquid wastewater droplets, transferring heat from the heated gas to the entrained liquid wastewater to partially evaporate the entrained liquid wastewater, and removing a portion of the fine entrained liquid wastewater droplets from the mixture to provide a demisted gas.
Abstract:
Bubble generator devices to produce a fluid stream of bubbles are described. Apparatuses that include any of the described bubble generator devices to treat waste and/or frac-water are also described.
Abstract:
A portable system for extracting iodine from brine on-site is disclosed. The portable system includes a mobile platform containing a treatment unit for oxidizing iodine ions into elemental iodine, an adsorption unit capable of binding iodine, and may also have an electrolytic cell and/or a gas-liquid separator. The treatment unit and the adsorption unit may be located in the same or different portable operating devices. When transported to a field site containing natural gas wells, the natural gas wells provide a fluid stream containing natural gas and brine. The separators can separate the natural gas from the brine, and the brine is then run through the treatment unit and the adsorption unit to bind iodine present in the brine. The brine is then returned to the natural gas well. Upon saturation, the portable operating device is transported to a second location, where iodine is extracted from the adsorption unit.
Abstract:
A water treatment system (50) utilizing granular activated carbon (GAC) for the removal of organic contaminants in a process water circuit (52), and including a carbon regeneration circuit (54) in fluid communication with the process water circuit. The carbon regeneration circuit may include a dedicated regeneration vessel (16), or the regeneration process may proceed within a GAC/water contactor (58) of the process water circuit. A process is described wherein spent GAC from the water treatment system is regenerated within the system with an oxidation process that minimizes damage to the carbon granules.
Abstract:
In a method for treating a liquid medium by reverse osmosis in a cyclic process, the pressure to the upstream side of the reverse osmosis membrane is generated by transferring the power of a basically free-falling weight to a hydraulic cylinder which generates the high pressure needed to overcome the osmotic pressure of the liquid medium.The system performing the method uses a weight medium capable of travelling vertically between an initial and terminal position. The power thereby generated is transmitted to a hydraulic cylinder containing the liquid medium which is subjected to a high pressure and delivered to the upstream side of a reverse osmosis unit. At the end of the process cycle the weight medium is released from the weight vessel, and a following cycle is initiated, refilling the hydraulic cylinder with untreated liquid medium
Abstract:
