Abstract:
A system and method for treatment of flowback water and produced water at an oil or gas wellhead includes a modular treatment facility that may be installed at a well site. The modular treatment facility includes separate and interchangeable modules that remove undesirable contaminants. The modules may be removed and replaced with similar modules when they are no longer effective at removing the contaminants. The spent modules may be transported to a regeneration center to be regenerated and transported back to a modular treatment facility.
Abstract:
A modular, on-site, wastewater treatment system removes total nitrogen, phosphorus, BOD, and TSS. A flow equalization module provides a constant flow rate to the system eliminating the adverse effects from variations in flow rate throughout the day. Treatment modules are similarly sized to provide a compact, modular system. The nitrification module is a fixed-film, flooded packed bioreactor to facilitate bioconversion of ammonia to nitrate. Aeration of the module provides the oxygen needed for the bioconversion as well prevents clogging of the film. Solids from the nitrification process are removed in a first cone-shaped settling tank. De-nitrification where nitrate is converted to nitrogen gas takes place in an anaerobic fixed-film bioreactor. Carbon-based bio-film carriers provide a carbon source for de-nitrification. A final cone-shaped settling tank separates solids from the treated wastewater. Additional modules to address removal of phosphorous or other contaminants can be added to the modular system.
Abstract:
Methods and apparatuses for the evaporation and condensation of water by utilizing latent heat of condensation and solar heating is provided. Various embodiments include a module that may be associated with a body of water and incorporate first and second dendritically liquid receiving channels, a dome, a lower chamber and an upper chamber. The first channel conducts water from the body of water to a reservoir located within the module. The second channel is in heat exchange relationship with the first liquid receiving channel and conducts water from the reservoir to the exterior of the module below the reservoir. The dome encloses the top of the reservoir and forms a vaporization chamber. An exit drain in the vaporization chamber leads to a collection channel for conducting demineralized condensate out of the module. Still other embodiments utilize at least two membrane layers having a plurality of dendritically-configured and/or nested channels.
Abstract:
Photovoltaic-powered reverse osmosis system. The system includes a photovoltaic panel for generating electricity and includes a heat exchanger in thermal contact with the photovoltaic panel. The salt-containing feed water is fed to a reverse osmosis unit to produce clean water therefrom. Fluid circuitry, including a pump, circulates the feed water through the heat exchanger to cool the photovoltaic panel and to heat the feed water. It also delivers the heated feed water to the reverse osmosis unit for desalination. Cooling the solar panel and heating the RO feed water increases the total amount of clean water produced. In a preferred embodiment, a thermal controller manages the temperatures of the photovoltaic panel and the feed water by controlling the flow of feed water through the fluid circuitry. The photovoltaic panel temperature is minimized and the temperature of the feed water is maximized subject to a constraint on maximum feed water temperature.
Abstract:
A wastewater treatment system includes a vessel and a plurality of media canisters contained in series therein. The vessel provides for linear flow of wastewater through the canisters for treating and removing contaminants. The canisters contain seal means to form a fluid tight seal against the inner wall of the vessel. The linear flow provides for increased flow rates and more efficient treatment and removal of contaminants. A method of using the treatment system to treat wastewater to remove or neutralize one or more contaminants therein is also described.

Abstract:
An apparatus and method for the treatment of sewage and waste comprising an enclosed pressurized vessel for receiving transported sewage and for treating the same to provide biological and chemical oxidation and sterilization and undesirable color, taste, odor, phenol, cyanide and phosphate reduction and the combination therewith of transporting, from a point of collection to the point of treatment, liquid sewage and waste which has tendencies to become septic and build up undesirable chemicals, gases, odors, bacteria and the like during the transportation due to the lack of proper oxygen content therein and devices positioned directly in the sewage as it is transported for supplying oxygen thereto to prevent the same from becoming septic, control the build-up of the aforesaid undesirables and stimulate growth of desirable aerobic bacteria. The preferred pressurized vessel receives high purity oxygen as O2 or O3 in an upper portion thereof to define a pressurized gaseous oxygen atmosphere and includes a device for injecting a stream of the sewage into the gaseous atmosphere and against a comminutor device for breaking the sewage into small particles to allow the sewage and waste to quickly absorb the oxygen under pressure to provide rapid biological and chemical oxidation and ozone sterilization and reduce the aforesaid undesirables.
Abstract:
System and method for micro-Super Critical Water Oxidation solids treatment of fecal waste are described. The system includes an injector vessel (112) and a reactor (114). The reactor can receive an injection of a slurry batch and an input of compressed air that is heated over time to a temperature at or above the critical point of water into the super critical fluid phase. A combined concentrator and phase separator (150)) can receive a treated output from the reactor and separate solid ash from liquid and gaseous effluent. A drying tunnel (170) can receive and dry the solid ash. The treatment process includes heating the slurry batch, within the reactor, to a temperature of at or above the critical point of water into the super critical fluid phase and maintaining the slurry batch a minimum temperature, within the reactor, for a predetermined treatment time to produce a treated output.
