    Abstract: Ultrapure water of high purity having extremely low TOC concentration is produced by efficiently degrading urea in raw water by biological activated carbon treatment even when the raw water contains ammonium nitrogen. The ultrapure water production method, where raw water is treated in a primary pure water system, and then the resulting water is treated in a subsystem, contains a step of treating pretreated water with chlorine based oxidizer added by a biological treatment means installed upstream to the subsystem. Chlorine based oxidizer is added so that the chlorine based oxidizer concentration is 5 times or more than the ammonium nitrogen concentration of water treated in the biological treatment means in terms of Cl2.

At least either a hypobromous acid or a water-soluble salt thereof is formed by reacting at least either a hypochlorous acid or a water-soluble salt thereof with a bromide in a liquid to be treated, wherein the at least either hypobromous acid a water-soluble salt thereof is formed by adding a modified chlorite to the liquid to be treated.

  • Publication number: 20100140185
    Abstract: An antimicrobial method of treating wastewater and a wastewater antimicrobial dispenser containing an antimicrobial agent for treating a body of wastewater to kill microorganisms by increasing the concentration metal ions therein. The antimicrobial method includes the step of increasing the effectiveness of the biocidal component in the body of wastewater to thereby lessen the need for a supplemental biocide by adding a compound containing a hydantoin ring where the compound containing a hydantoin ring may or may not have any antimicrobial properties. The antimicrobial agent including a source of biocidal metal ions and a compound containing a hydantoin ring where the antimicrobial agent may be a powder, a liquid a solid or combinations thereof.

  • Patent number: 7727465
    Abstract: A system and method for extracting active elemental iodine from the contact of water with stored crystal iodine and for introducing the extracted elemental iodine into a water supply line and/or otherwise making the extracted elemental iodine available for an intended use. The system operates by allowing a portion of the water entering from a water supply line to be redirected to a first housing where it makes contact with stored crystal iodine causing to extract active elemental iodine. The iodinized water leaves the first housing and enters a second housing where it makes contact additional stored crystal iodine to help stabilize the elemental iodine concentration. The system can be designed to provide the elemental iodine in more than one potency concentration through the use of a metering valve and different travel routes for the elemental iodine out of the second housing.

  • Publication number: 20090294381
    Abstract: The invention relates to the control of pH in water where hydroxyl ions are being produced by adding to the water an amount of transition metal salt sufficient to bind with hydroxyl into a slightly soluble or insoluble reaction product, thereby removing sufficient hydroxyl ion from the water to lower the pH thereof. This technique is particularly suitable for pH control in pool or spa water that is sanitized using chemical or electrolytic chlorination, where the sanitation process causes the pH in the water to rise. The invention also relates to apparatus for dispensing water treatment materials to water, and to methods for controlling phosphate levels and algae in water.
