20110233141 | WASTEWATER TREATMENT SYSTEM AND METHODS FOR CONSTRUCTING THE SAME - A wastewater treatment system capable of reducing or eliminating point discharge. The wastewater treatment system includes a wastewater treatment unit and a wastewater treatment lagoon in fluid communication with the wastewater treatment unit. The wastewater treatment lagoon can be located at a higher elevation than the wastewater treatment unit. The wastewater treatment lagoon can preferably be a combined evaporation/infiltration lagoon. A drip irrigation system can also be included around the periphery of the wastewater treatment lagoon and in fluid communication with the wastewater treatment lagoon. | 09-29-2011 |
20130306572 | Pressurized Gas Lifting and Gas Rejuvenation - Devices, processes, systems, and articles of manufacture adapted to treat contaminated fluid, such as organic wastewater, are described. These are described to include lifting contaminated fluids, treating contaminated fluids, or both, through gas application. In certain designs, gas, such as pressurized air, may be used to lift contaminated fluids, such as organic wastewater (i.e., water having contaminating organics of some kind, e.g. residential septic wastewater). In certain designs, gas, such as pressurized air, may also be used to treat fluids interfacing with the gas. | 11-21-2013 |
20140263088 | METHOD AND SYSTEM FOR THE TREATMENT OF WATER AND FLUIDS WITH CHLORINE DIOXIDE - Embodiments of the invention relate generally to methods and systems for treating aqueous systems associated with industrial wastewater applications and gas and crude oil drilling, pumping and production to reduce or eliminate contamination. In one embodiment, a method includes: an aqueous volume having an initial oxidant demand, an oxygen-containing oxidant and at least one chlorine oxide at substoichiometric amounts in an amount sufficient to eliminate the oxidant demand. The system includes: an aqueous treatment system comprising a containment system; at least one apparatus for introducing an oxygen-containing oxidant; and at least one apparatus for introducing at least one chlorine oxide into said containment system at controlled, substoichiometric quantities. | 09-18-2014 |
20160096753 | Long Term Dual Biocide and Hydrogen Sulfide Remediation - In wellbore construction it has become environmentally and economically practical to treat flow back and produced water at the well site. Typically the flow back and produced water is initially contained in an open air pond. The water is then run to a treatment system to remove particulates and then deposited in a second clean pond. The water in the second clean pond may be allowed to sit in the pond for weeks before it is pumped out to be taken and disposed of or most likely to be used as a water source in the construction of a different well. Unfortunately even though the water may have initially been treated with the biocide due to the open environment to water is usually re-contaminated with both nutrients and both aerobic and anaerobic bacteria. The anaerobic bacteria usually include sulfur reducing bacteria which in turn produces hydrogen sulfide dissolved in the water. It has been found that an effective way to treat the clean pond to prevent contamination of the clean pond of sulfur reducing bacteria and its consequent hydrogen sulfide is to initially treat the second pond with a short-term or quick kill biocide as well as with the hydrogen sulfide scavenger that may then act as a long term biocide. | 04-07-2016 |

20120006757 | SEPARATING SAND FROM FLUIDS PRODUCED BY A WELL - A settling system may be used to separate and/or remove solid particles, such as sand, from fluids produced by wells. The container of the settling system may be cleaned without need for manned-entry. | 01-12-2012 |
20120261353 | SEPARATOR - A solids separator for use in a sewer overflow chamber having an inlet, flow chamber and main outlet, whereby liquid, having solids entrained therein, flows from the inlet through the flow chamber to the outlet, the solids separator comprising: an overflow weir over which liquid flows during overflow into a separation chamber; a filter in the separation chamber that filters solids and allows liquid to pass through to an overflow outlet; and a return outlet through which filtered solids return back into the flow chamber, wherein the filter includes an array of vertical filter members spaced from a top of the overflow weir such that a liquid flowing over the weir passes through the filter members. | 10-18-2012 |
20130075342 | ENVIRONMENTAL REMEDIATION SYSTEM - An apparatus, system and method for removing and treating contaminated materials on a bottom of a body of water and introducing growth packets to revitalize the treated bottom of the body of water. The structure may comprise a vessel with an open face. The vessel may be lowered down to the bottom of the body of water with the face facing down. As a result, the vessel and the bottom form an isolated space. The structure may comprise at least one agitating device(s) for stirring up the materials inside the vessel so as to form a mixture containing the sediment materials which in turn contain the contaminants. Multiple at least one pipe(s) may be coupled to the vessel for transporting the mixture out of the vessel for processing (filtering, treating with chemicals, etc.) so as to neutralize or eliminate the contaminants in the mixture. Then, the treated mixture can be returned to the inside of the vessel via the at least one pipe(s). | 03-28-2013 |
20130270193 | METHOD FOR WATER SANITISATION - A method of sanitising swimming pool water including forming a matrix comprising one or more insoluble metal salts adjacent an at least one anode and/or an at least one cathode of an electrolytic cell. When water from the pool is passed through the active electrolytic cell the presence of the matrix of insoluble metal salts enhances the generation of active oxygen species which results in sanitisation of the swimming pool water. | 10-17-2013 |
20140319075 | LIQUID TREATMENT DEVICE - A liquid treatment device for treatment of liquid contaminated with living organisms comprising a rotating means having a first surface for receiving the liquid to be treated, where the first surface is provided with engaging means for engaging the liquid and to provide acceleration to the liquid upon rotation of the rotating means, stationary means which is stationary relative to the rotating means and arranged to form a boundary in order to constrict the liquid on the first surface of the rotating means, where the stationary means is arranged to define at least one slit between the first surface of the rotating means and a first end of the stationary means allowing the liquid to pass between the rotating means and the stationary means, and where the engaging means are at least provided on a surface area of the rotating means that interacts with the at least one slit. | 10-30-2014 |
