  • Patent number: 10023487
    Abstract: A method or process for treating wastewater containing high organics, silica, boron, hardness, and suspended and dissolved solids. The method includes degasifying the wastewater for the removal of dissolved gases and thereafter chemically softening the wastewater. After the chemical softening step, the wastewater is directed through a media filter or membrane which removes additional solids and precipitants. Thereafter the wastewater is directed through a sodium ion exchange that further softens the wastewater. The effluent from the ion exchange is directed through a cartridge filter and the effluent from the cartridge filter is directed through one or more reverse osmosis units. At a selected phase of the process, prior to the wastewater reaching the reverse osmosis unit or units, the pH of the wastewater is raised and maintained such that the pH of the wastewater reaching a reverse osmosis unit is at a pH greater than 10.5.

  • Publication number: 20130098819
    Abstract: An oxygen and hydrogen emitter that is an electrolytic cell is disclosed. When the anode and cathode are separated by a critical distance, very small microbubbles and nanobubbles of oxygen and hydrogen are generated from aqueous solutions. The very small bubbles remain in suspension in the aqueous solution, forming a solution saturated in oxygen and hydrogen. A flow-through model for oxygenating and adding hydrogen bubbles in flowing water for water softeners is disclosed. Increasing the oxygen and hydrogen content of flowing water in residential and commercial water softeners to reduce sodium usage and increase resin regeneration efficiency with the use of an emitter is disclosed.

  • Patent number: 8394267
    Abstract: According to one embodiment, in order to eliminate impurities, and the like, water to be treated is passed through each of reactor vessels, phosphorus contained in the water to be treated is removed by using an adsorbent, and thereafter the liquid held in each of the reactor vessels is discharged through each of first to third treated water discharge paths, thereby eliminating the impurities, and the like derived from the water to be treated. It is possible to eliminate the influence of the impurities in the water to be treated on the discharged desorption agent liquid containing phosphorus from the phosphorus adsorbent can be eliminated, and hence it is possible to obtain a phosphorus-containing liquid containing no substance other than the recovered phosphoric matter material.

  • Publication number: 20120263801
    Abstract: Contaminants are filtered from a fluid flow stream and the filter is regenerated by a process including steps of: providing a filter material comprising both carbon and potassium iodide; passing a contaminated fluid stream in contact with the filter material; adsorbing contaminants from the fluid stream onto surfaces in the filter material; passing an electric current through the filter material with adsorbed contaminant thereon; disassociating contaminant from the surfaces of the filter material; and removing disassociated contaminant from the filter material by carrying away the disassociated contaminant in a fluid flow mass. Separately, a stable, active iodine solution is also provided for numerous deodorizing and disinfecting applications.

  • Patent number: 8157972
    Abstract: An electrolytic water treatment system improving upon the electrode life of electrolytic oxygen generators by reducing mineral precipitation and fouling that typically occurs in water treatment systems. The electrolytic water treatment system can include a softened water bypass stream into which a flow-through electrolytic element can be positioned. By eliminating exposure of the electrolytic element to hard water, scale formation on electrodes can be significantly reduced such that polarity reversal cycles of the electrolytic element decrease in frequency.

  • Publication number: 20110180477
    Abstract: A low energy system and process for seawater desalination wherein the system has at least an electrodialysis apparatus that produces partially desalinated water and a brine by-product, an ion exchange softener, and at least one electrodeionization apparatus. The softener treats the partially desalinated water stream to remove or reduce the amount of scaling material in order to maintain deionization apparatus efficiency and reduce energy consumption. The softener has the capability of removing a higher ratio of calcium ions to magnesium ions than is in the partially desalinated stream, thereby reducing softener size and energy use. The deionization apparatus produces product water of the desired properties. The brine stream may be used to regenerate the softener.

  • Publication number: 20100320147
    Abstract: Disclosed is an improved water treatment cavitation reactor cone. The tank operates on a continuous flow of fluids which are subjected to ultrasonic waves in combination with a high level of injected ozone. The treatment tank includes a tangential inlet that induces a rotating flow into the tank thereby increasing the mixing of the ozone within the effluent. The effluent is further treated with DC current. The treatment tank provides a cost efficient and environmentally friendly process and apparatus for cleaning and recycling fluids as contaminated as frac water, used to stimulate gas production from shale formations, as well as other types of fluids having various levels of contaminants such as aerobic and anaerobic bacteria and suspended solids. The calcium carbonate scaling tendency is reduced to an acceptable level without the use of acids, ion exchange materials, or anti scaling chemicals which is of economical and environmental significance and benefit.
