  • Chlorine Dioxide gas detection: A comprehensive guide

    Introduction Some years agoago, the bleaching process in the paper industry was changed from using Chlorine (Cl2) as bleaching agent to Chlorine dioxide (ClO2). This was a challenge forThis posed a major challenge to industrial hygienists, as there were no sensors or detectors available that were specific to Chlorine dioxide: There was no sensor technology for gas detectors available that ...

  • Reference: Clever water recycling with chlorine dioxide

    Vapour water at the Crailsheim-Dinkelsbühl dairy is disinfected and then returned to the production process by means of a chlorine dioxide system. The great news is that this significantly reduces water consumption and operating costs. Fewer costs The 160 members of staff at the diary "Milchwerk Crailsheim-Dinkelsbühl eG" process around 130,000 tonnes of milk a year, ...

  • Using RuO2 anode for chlorine dioxide production in an un-divided electrochemical cell

    Chlorine dioxide is a well known powerful disinfectant. Although there are several chemical and electrochemical methods developed for on-line chlorine dioxide generation, the details are mostly confined as patents. We studied in this work the electrochemical generation of dissolved chlorine dioxide from an un-buffered solution of sodium chlorite and sodium chloride mixture in an un-divided ...

  • Case study - Elemental chlorine free kraft pulp bleaching and chlorine dioxide scrubbing

    Chlorine Dioxide - CIO2 Scrubber Packing at Kraft Pulp Mills Elemental Chlorine Free - ECF - bleaching of wood pulp using Chlorine Dioxide, CIO2, as the primary bleaching agent eliminates dioxin emissions. This is a reflection of the fact that as a bleaching agent CIO2 is 10 times more reactive than elemental Chlorine, Ck. As a powerful oxidizing agent CIO2 must be generated on site - ...

  • From Gas to Liquid: Large-Scale Chlorination System Conversion

    Abstract A number of wastewater treatment facilities using gas disinfection have decided to convert to liquid disinfection for several reasons including safety, regulatory, security, and economic factors. An optimal technology plan should be developed to facilitate the conversion. This presentation provides a case study of a large chlorine disinfection system, and demonstrates key issues of ...

  • Oxidized fulvic acid adsorption on activated carbon

    This study evaluates and compares the parameters of equilibrium adsorption from aqueous solutions of river fulvic acids (FA) and peat fulvic acids. Compared to peat FA, the river FA had lower biodegradable dissolved organic carbon (BDOC). We observed a tendency for correlation between change of Gibbs free energy of adsorption and BDOC value. A chlorination dose of 1.4 mg L−1 did not ...

  • Photocatalytic and photoelectrochemical inactivation of Escherichia coli and Staphylococcus aureus

    Water disinfection usually requires expensive chemicals or equipment. Chlorination is a common disinfection method, although it is not able to inactivate all pathogens. High concentrations of residual chlorine also cause an unpleasant taste and smell in drinking water. As an alternative, photocatalysis and photoelectrochemical treatment has a high disinfection potential in drinking water by ...

  • Biocidal Products Regulation - White Paper

    The European Biocidal Products Regulation (Regulation (EU) No. 528/2012) stipulates that biocidal products may only be made available and used on the market if they are certified in accordance with this regulation. Unlike the previous biocidal products legislation, so-called “in-situ” procedures such as electrolysis, chlorine dioxide and ozone now also fall under this certification ...

  • Correlations between surrogate nitrogenous organic precursors and C-, N-DBP formation

    Nitrosamines have been emerging as disinfection byproducts in drinking water using source water impacted with domestic wastewaters. Nitrogenous organic compounds are suggested as precursors of nitrosamines, but many of them have not been identified. This study investigated the correlations between nine selected nitrogenous organic compounds with different characteristics and corresponding ...

  • Cleaning mold containing surfaces

    Once a determination is made that a moldy surface can be cleaned instead of removed or demolished, what cleaning agents are effective in removing or killing the mold? Many factors influence the selection of a cleaning agent. 1). The type of surface to be cleaned: Is it porous? Hard such as cement or sheetrock? Soft, such as cloth, fabric or wallpaper? Absorbent and thick such as rugs, ...

  • Drought Forces Push to Recycle, Reuse and Potential in Brackish Water for Oil & Gas Industry: Interview with BioLargo CEO

    UPTICK Interview: BioLargo's AOS Filter Delivers Abundant Clean Water Even In Drought The headlines are full of discussion on water shortages and drought with few options consistently noted beyond the need to conserve and manage the precious resource. To gain perspective on the problem and explore viable solutions UPTICK Newswire interviewed ...
