Abstract:
The present invention relates to a process for producing an electrolyte comprising the steps of (a) providing an aqueous solution comprising one or more alkaline earth or alkali metal chloride salts in a concentration of 0.2 to 12 g/l; (b) passing the solution through a first cathode chamber and subsequently through at least a second cathode chamber to obtain a catholyte; (c) passing at least part of the catholyte through a first anode chamber and subsequently through at least a second anode chamber to obtain an anolyte, wherein the anode in at least one of the anode chambers is shaped in the form of a rod.
Abstract:
The present invention relates to efficient methods of controlling biological conversions while simultaneously removing and converting some of the generated products. More specifically, and for example, the present invention discloses electrochemical processes to remove and capture potentially toxic ammonium during anaerobic digestions and to remove and capture carboxylic acids during bioethanol production. The invention can thus be used to enhance bioproduction processes via controlling pH and/or reduction/oxidation, in combination with in situ product recovery.
Abstract:
The invention provides a liquid composition when used for maintenance of a body of water, the liquid composition comprising a solution of magnesium and potassium salts, at least one of which is a halide salt. Preferably, the liquid composition comprises Mg 2+ from the magnesium salt in an amount of from about 6000ppm to about 15 000ppm; K + from the potassium salt in an amount from about 40 000ppm to about 120 000ppm and hypohalite from the halide in an amount from about 100 000ppm to about 400 000ppm.
Abstract:
A cleaning solution generator (40) comprising a housing (42) with an interior reservoir (60) and a brine tank (102), the cleaning solution generator (40) being configured to generate an alkaline solution from a mixed solution and to operably direct the generated alkaline solution to the interior reservoir (60) of the housing (42).
Abstract:
An efficient method and system for the electrochemical treatment of waste water comprising organic and/or inorganic pollutants is disclosed. The system comprises an electrolytic cell comprising a solid polymer, proton exchange membrane electrolyte operating without catholyte or other supporting electrolyte. The cell design and operating conditions chosen provide for significantly greater operating efficiency.
Abstract:
A method for generating a potentised coagulant solution which accelerates coagulation in water containing high organic contaminants is disclosed. The method comprises electrolyzing an aqueous solution of a coagulant compound to provide a chemical complex with at least one hydroxyl group.
Abstract:
A method for electrolytically generating a biocide having an electron deficient carrier fluid and chlorine dioxide, including providing a carrier fluid; providing a pair of electrodes interposed by a semi-permeable membrane within a vessel for creating a first passageway and a second passageway, an anode electrode of the pair of electrodes disposed in the first passageway, cathode electrode of the pair of electrodes disposed in the second passageway; flowing the carrier fluid through the vessel; applying an electric potential to the pair of electrodes to produce an oxidative acidic fluid, a reductive alkaline fluid, and anodic gases in the container; removing the fluids and gases from the vessel; mixing a portion of the anodic gases with the reductive alkaline fluid to produce a hypochlorite solution; and mixing a chlorite brine with the hypochlorite solution, followed by the introduction of additional oxidative acidic fluid to release the biocide.
Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von elektroaktiviertem Wasser, welches in einem geschlossenen Behältnis (9) bei einer Lagertemperatur von 15°C bis 25°C während wenigstens 3 Monaten eine keimreduzierende, keimabtötende Wirkung aufweist, welches dadurch gekennzeichnet ist, dass man Wasser in einem geschlossenen Kreislauf (7) mehrmals durch eine Ionisations-Vorrichtung (2) pumpt, wobei dem Kreislauf-Wasser in beliebiger Reihenfolge eine Natriumchlorid-Lösung und gasförmiges Kohlenstoffdioxid zudosiert werden, wobei eine Kontroll- und Steuerungs-Einheit (3) die Stromstärke und die Spannung in der genannten Ionisations-Vorrichtung (2) sowie die Durchflussgeschwindigkeit und die Zugabe der Menge der Natriumchlorid-Lösung und der Menge des gasförmigen Kohlenstoffdioxids bezüglich vorbestimmter Werte kontrolliert und steuert, und dass man anschliessend das so erhaltene Produkt, also das elektroaktivierte Wasser, entweder in ein Behältnis (9) abfüllt und verschliesst oder direkt verwendet.
