摘要:
The present invention discloses a process for producing an electrolytic water, wherein a to-be-electrolyzed water containing less than 0.1 mM of a water-soluble inorganic salt, 0.05 to 0.5 mass % of a hydroquinone derivative and 1 to 50 mM of L-ascorbic acid or a derivative thereof is fed into a diaphragm-free electrolytic cell of continuous flow type at a flow rate of 5 to 3,000 l/min and electrolysis is conducted continuously at a current density of 0.003 to 0.1 A/cm2. The process can produce an electrolytic water having a high skin-whitening effect owing to the reducing action of L-ascorbic acid and the melanin formation-suppressing effect of hydroquinone derivative.

The invention relates to a process for eliminating nitrogenous organic compounds from a salt-containing water which contains more than 0.5% by weight of salt in the form of CaCl2 or NaCl, less than 200 ppm of dissolved carbonic acid or carbonates and more than 50 ppm of nitrogenous organic compounds, by treating the water by wet oxidation at a temperature of below 100° C. with chlorine or a chlorine-containing oxidizing agent and feeding this, preferably after additional oxidation with a gaseous oxidizing agent and/or by adsorption with an adsorbent, to an electrolysis for producing chlorine and/or sodium hydroxide solution.
摘要:
An electrolytic method is provided for purifying an aqueous stream, including at least one contaminant ion. In one embodiment, the eluent stream flows through a purifying flow channel, including ion exchange bed, an electric field is applied through the flowing eluent stream in the purifying flow channel, and the contaminant ion is removed from the eluent stream. In another embodiment, no electric field is applied and the ion exchange bed is periodically regenerated. Two beds may be used with one bed on line while the other bed is regenerated followed by a reversal of flow.

Described herein is a physiologically-balanced, acidic solution. Typically the solution is prepared by a chemical reactions or by the electrolysis of a solution comprising a mixture of an inorganic salt to form a physiologically balanced solution. This invention also relates to methods for use of the solutions, including a specialized bandage which may be used in combination with the solutions, or optionally with other topically applied materials. A mixture of inorganic salts and, optionally minerals, is used in order to mimic the electrolyte concentration and mixture of body fluid in an isotonic state. The solution typically comprises of one halide salt of lithium, sodium, potassium, calcium, and other cations. Typically the halide is fluoride, chloride, bromide, or iodide, and most typically chloride. A typical electrolyzed solution of the present invention has a pH within the range of about 2 to about 5, an oxidation reduction potential within the range of about +600 mV to about +1200 mV, and hypohalous acid concentration in the range of about 10 ppm to about 200 ppm. The solution has bactericidal, fungicidal, and sporicidal properties. The composition of the invention is nontoxic and has antibacterial properties, and is useful in any application in which antimicrobial properties are desirable.

摘要:
The invention relates to a method for oxidative treatment of aqueous liquids by means of oxidants. In this method, the aqueous liquid is passed through an electrolysis reactor, in which highly aggressive oxidants (OH—, O3, H2 O2) are produced in the electrochemical decomposition of the water. Black and/or grey water is used as the aqueous liquid, which is liberated from coarse particles and mechanically broken up thereafter, before it is passed into the electrolysis reactor. Gaseous portions are released and inorganic residual components are filtered out. The remaining residual liquid, which consists substantially of water, can be introduced into a fresh, wash- and/or rinse water system.(only FIGURE)
