Abstract: A sump sanitizing system is provided including a UV energy source within a sump tank. The UV energy source may be a light bulb or tube that is submersed in the collected groundwater water within the sump tank. The light bulb or tube may be self contained and waterproof, and may utilized light emitting diodes (LED), or other functional similar UV producing mechanism. For new sump installations the system may be integrated within the other operational components and controls utilized for water removal. For aftermarket installations, a UV source may be fixed to or mounted within an existing sump tank in a manner so as to not interfere with the systems other operations. An electrical power supply may be in communication with the UV source. Power may be communicated in a constant manner, or controlled for intermittent operation with a timer or other type of controller.

Abstract: Technologies are described for a process for in situ treatment of contaminated soil(s), water, waste, sludge, wastewater, sediment, other contaminated matrix, or combination thereof. The process comprises applying a reactive or treatment material and an adjunct to the contaminated matrix or in a flow path of the contaminant in the matrix. The adjunct is controllably released into the matrix and contributes to the treatment of the soil(s), water, waste, sludge, wastewater, sediment, other contaminated matrix, or combination thereof.

Abstract: The purpose of the invention is to provide in situ treatment and flow diversion of contaminated groundwater without the need for an external energy source. The primary means by which contaminated groundwater is treated in situ within a subsurface environment is through the use of the use of the modular SubflowRx and interrelated components that work together or independently to control groundwater flow outside the system as well as diverting contaminated groundwater inside the system for extended treatment. The present disclosure provides embodiments, examples, and advantages of how the components work to achieve this common purpose.

Abstract: Described herein relates to an optimum, low maintenance and low-cost filtration media which may be implemented near a source water location as a pretreatment to remove tannic acid and/or humic acid (color) from dissolved natural organic matter (NOM) (i.e., tannic acid, humic acid) to impede the prompt production of disinfection by-products collectively termed trihalomethanes in drinking water treatment processes. In an embodiment, the filtration media may comprise a composition having a ratio of at least 83% sand, at most 5% clay, at most 6% ZVI and at most 6% perlite by percent volume.

Abstract: An iron containing bioreactor for treating explosive compounds and other organics in contaminated surface water is disclosed. The bioreactor can be located either on-ground or in-ground at a location across which contaminated surface water flows. In one configuration the reactor is made up of (i) indigenous microbes, (ii) acetate, (iii) a low density iron-containing bed, and contains anaerobic zones in at least one portion of the flowpath. The reactor reduces the concentration of explosive compounds to below 10 ppb and also maintains this explosive compound reduction level for a period of at least one year without replenishing the microbes or iron.

Abstract: The disclosure relates to a staggered electrode bio-electro-Fenton groundwater circulation well system, including a groundwater circulation well, a water pumping and injecting assembly and an in-well bio-electro-Fenton assembly. The water pumping and injecting assembly is configured to realize water pumping and injection between different screening sections of the groundwater circulation well. The bio-electro-Fenton assembly arranged in a first screening section of the groundwater circulation well includes at least one electrode device. A cathode and an anode of the electrode device form a spatially staggered arrangement according to different distribution areas. According to the disclosure, the spatially staggered arrangement of the cathode and the anode, the influence of oxygen on an anaerobic environment of an anode chamber in the electrode device is greatly reduced while ensuring the cathode takes oxygen as an electron acceptor, and the constructed bio-electro-Fenton system can accelerate the decomposition of organic pollutants in the groundwater circulation well.

Abstract: The invention relates to a method and a system for purification of water in a water purification system. The water purification system comprises first and second mixing reactors, first and second flotation reactors and first and second filters all serially and fluidly connected in a flow direction of the water as well as an electrolyzer. During the process, electrochemical synthesis of the reagents takes place in the cathode and anode chambers of the electrolyzer, respectively. Moreover, the electrochemically synthesized catholyte and anolyte are dosed into the water kept in the first and second mixing reactors, respectively. Then the mixtures in the first and second mixing reactors are mixed. After that, the flow of the treated water leaving the mixing reactors is passed through the first and second flotation reactors and afterwards through the first and second filters downstream of the first and second mixing reactors.

Abstract: A method for a removal of HA from water is provided, including using PMS as an oxidant, using VI or UV as an activation source, and adding a MIEX resin into the water for a reaction. By applying the method, irradiated by the visible light, a VI/MIEX/PMS system is coupling to strengthen adsorption process, thereby realizing a relatively high removal effect on the HA; therefore, the VI/MIEX/PMS system can be suitable for a large-scale environment performed by water treatment, and a removal efficiency thereof on HA can reach 60% or above. Moreover, irradiated by the ultraviolet light, a UV/MIEX/PMS system can be suitable for small and medium-sized environment performed by rapid water treatment, and can cope with sudden HA pollution of water source in a medium and small range, and a removal efficiency thereof on HA can reach 90% or above.
