The invention relates to a set of electrocatalytic strong oxidizer materials, comprising a nano-function anode material which compounds nano oxide particles and catalyzes metal nano particles on a titanium substrate, and a nano-function cathode material which takes titanium or stainless steel as a substrate and introduces transition metal nano-particles on the surface thereof. By the electro-catalytic advanced oxidation technology, under the catalytic action of electrocatalytic strong oxidizer materials, water body can generate a hydroxyl radical with strong oxidizing performance and an oxygen radical; and if a chloride ion exists in water, hypochlorite can be generated. Under the joint action of a plurality of types of strong oxidizers, the algae cells in the water body and various harmful bacteria can be killed; and simultaneously the ammonia in water and the water-soluble organic matters can be degraded, so the goal of purifying water is achieved. According to the electrocatalytic advanced oxidation theory, the electrocatalytic strong oxidizer materials does not need to add any chemical agent when in application, does not have secondary pollution, and has good safety, high efficiency and low energy consumption.

An Anti-Terrorism water quality monitoring system for continuously monitoring a potable water treatment system and related potable water distribution network that provides potable water to a municipality, city, housing development or other potable water consumer. The system includes the collection of data from the water distribution system and from the water treatment facility and from advanced separation processes which are integrated into analytical instruments. The data collected are stored in a remote database on a remote server computer or bank of computers and accessible by Homeland Security or its designated agency. Preferred parameters of monitoring include the turbidity and disinfectant such as chlorine, hypochlorous acid, sodium hypochlorite, calcium hypochlorite, ozone, chlorine dioxide, chloramines, hydrogen peroxide, peracetic acid.

Its advantages are high medical effect to protect liver and take care of health, and low cost.

An Electrolysis cell assembly to produce diluted Sodium Hydroxide solutions (NAOH) and diluted Hypochlorous Acid (HOCL) solutions having cleaning and sanitizing properties. The electrolysis cell consists of two insulating end pieces for a cylindrical electrolysis cell comprising at least two cylindrical electrodes with two cylindrical diaphragms arranged co-axially between them. The method of producing different volumes and concentrations of diluted NAOH solutions and diluted HOCL solutions comprises recirculating an aqueous sodium chloride or potassium chloride solution into the middle chamber of the cylindrical electrolytic cell and feeding softened filtered water into the cathode chamber and into the anode chamber of the cylindrical electrolysis cell.

The present invention relates to low pH antimicrobial solutions comprising hypochlorous acid, water, and, optionally, a buffer. The inventive low pH antimicrobial solutions have a pH from about 4 to about 6 and are useful for treating impaired or damaged tissue and for disinfecting surfaces. Chemical processes for the production of the low pH antimicrobial solutions are also provided wherein chlorine gas is added to a buffer solution containing a buffering agent and water. The present invention also provides an electrochemical process for the production of the low pH antimicrobial solutions.

An apparatus for treating water by electrolysis method is composed of DC power supply controller, water supply-discharge unit, two electrolyzing cathode bathes, electrically isolating plate unit, water scale depositing unit, and two electrolyzing anode bathes. The electrolytic reaction of water can make the calcium carbonate and the hydroxide of heavy metals to be deposited in anode bathes and the Cl2, O2, the radicals of hypochlorous acid and chloric acid, and ozone to be generated in cathode bathes.

The invention discloses a pyridine quaternary ammonium salt type halamine antibacterial agent with a structure represented by a general formula I, wherein n is an integer of 1-10. The preparation method comprises the following steps: a, 5,5-dimethyl hydantoin is placed in an acetone solution doped with anhydrous potassium carbonate; refluxing is carried out for 30min, and dibromoalkane is added; refluxing is continued for 4h, such that a bromo-alkyl hydantoin compound is obtained; b, the obtained bromo-alkyl hydantoin compound is dissolved in acetonitrile; excessive pyridine is added; heating and refluxing are carried out overnight; concentration is carried out, such that a pyridine bromide quaternary ammonium salt type halamine precursor is obtained; the precursor is delivered through chlorine-type anion exchange resin, such that a pyridine chloride quaternary ammonium salt type halamine precursor is obtained; and c, the obtained pyridine chloride quaternary ammonium salt type halamine precursor is dissolved in a mixed solution composed of deionized water and tert-butanol; tert-butyl hypochlorite is added, and stirring is carried out for 2-4h while protected from light, such that the pyridine quaternary ammonium salt type halamine is obtained. The method has the advantages of easy-to-obtain raw materials, and relatively simple synthesis method. The method has a prospect of industrialized application.
