They are mainly from human or animal feces in the aquatic environment. These feces also contain - in addition to pathogens - also usually a larger amount of Escherichia coli and other harmless bacteria. In the routine monitoring of drinking water quality, it is therefore sufficient to look for these typical fecal organisms, ie Escherichia coli or enterococci in the water samples. These bacteria are therefore called "indicator or indicator organisms". For example, if the bacterium Escherichia coli were not detectable in 100 milliliters of a water sample, it indicates that potentially dangerous microorganisms are not present in concentrations that could cause disease PowerPoint-Präsentation: General Microbiological Parameters and Indicator Parameters Part I Microbiological parameters and indicator parameters for which microbiological analysis methods are specified The reference methods given below shall be used to analyze the microbiological quality of drinking water in accordance with the relevant version of the standard in question. When updating the standard, a transition period of one year from the date of publication of the German standard procedure applies. Within this period, the investigation bodies accredited under § 15 (4) must adapt the existing accreditations to the requirements of the updated standard in accordance with the standard DIN EN ISO / IEC 17025.

In this case, turbidity values ​​in the course of the particle-separating stage in the range of 0.1-0.2 NTU should be strived for, if possible, to be undercut. The communication from the Federal Environmental Agency: "Requirements for the treatment of surface waters for drinking water with regard to the elimination of parasites" (published in Bundesgesundheitsblatt 12/97) is expressly noted. PowerPoint-Präsentation: TwinOxide in drinking water § 6 Chemical requirements In drinking water, chemical substances must not be present in concentrations that cause damage to human health.  (2) In drinking water, the limit values ​​for chemical parameters set out in Appendix 2 shall not be exceeded. The serial number 4 of Annex 2 Part II shall be applied from 1 December 2013; until 30 November 2013, the limit of 0.025 milligrams per liter applies.

The solution is prepared from water and the TwinOxide  Component A and Component B in the mixing tank and subsequently transferred to the dosing tank from which it is dosed. The transfer and dosing pump are controlled by a PLC inside the control panel. Two activated carbon filters prevent the release of hazardous gases. PowerPoint-Präsentation: Preparation of the solution Plug in the power supply cable into a 230V 50Hz socket. Switch on the transfer- and dosing pumps. Connect the fresh water hose to the mixing tank. Open the (ventilation) ball valve of the activated carbon filter. Open the ball valve of the fresh water supply. Fill the mixing tank with fresh water (until the green light is on). Close both ball valves (fresh water supply and activated carbon filter). Open the bleeding valve of the transfer pump counter clockwise. Push and hold the transfer pump button for 3 sec. to start priming. When liquid exits the retour hose hold the transfer pump button for 5 sec. to stop priming. Close the bleeding valve clockwise (tighten only lightly by hand). Unscrew and open the lid of the mixing tank. Add TwinOxide  component B to the mixing tank. Add TwinOxide  component A to the mixing tank. Close the mixing tank, ensuring a tight and secure closing. Push the button of the transfer pump once to start a 3 hour mixing and transfer procedure . After the 3 hour mixing time, the TwinOxide  0.3% ClO2 solution is transferred to the dosing tank automatically. The transfer pump will pause when the dosing tank is full. The mixing and transfer procedure will be reset automatically when the mixing tank is empty. PowerPoint-Präsentation: Dosing of the TwinOxide solution Make sure that the right activation mode for the dosing pump is selected (page 12). Open the bleeding valve of the dosing pump counter clockwise. Hold the dosing pump switch to the left for priming. Release the prime switch when liquid comes out of the bleeding hose. Close the bleeding valve of the dosing pump clockwise (tighten only lightly by hand). Set the dosing pump switch on “AUTO” to dose the TwinOxide  solution automatically .

According to the TVO 2011, an increase of 25μg / l is permissible. PowerPoint-Präsentation: DVGW-W224 method for the disinfection of drinking water with chlorine dioxide Chlorine dioxide can be used to kill or inactivate freely-suspended microorganisms, including bacterial and viral pathogens in the water. Condition: turbidity free water (see DVGW W 290 A) PowerPoint-Präsentation: DVGW-W224 method for the disinfection of drinking water with chlorine dioxide In surface waters there is the possibility of fecal contamination. A high concentration of germs is possible. Therefore: Before the disinfection a mechanical removal of the particles is urgently necessary. This also applies to a pre-cleaning of the water through filters. PowerPoint-Präsentation: DVGW-W224 method for the disinfection of drinking water with chlorine dioxide The Drinking Water Ordinance must be strictly adhered to. The use of chlorine dioxide for the oxidation of water constituents is not permitted.

PowerPoint-Präsentation: DVGW-W224 method for the disinfection of drinking water with chlorine dioxide The reaction rate of chlorine dioxide formation increases with increasing pH (Equation 2) It increases with decreasing pH (Equation 3) Solutions with a high concentration of chlorine dioxide break down very quickly. TwinOxide solutions disintegrate very slowly due to the low chlorine dioxide concentration PowerPoint-Präsentation: DVGW-W224 method for the disinfection of drinking water with chlorine dioxide At 40 ° C, the AGW value of 0.1 vol% is reached at 43 mg / l chlorine dioxide At 20 ° C, the AGW value of 0.1% by volume is reached at 91 mg / l chlorine dioxid In practical cases, the critical AGW value is never reached PowerPoint-Präsentation: . a PowerPoint-Präsentation: . PowerPoint-Präsentation: The TwinOxide process is an essential complement to the techniques for the in-situ production of chlorine dioxide solutions and their automatic dosing of the plants for the production of drinking water. Due to the flexibility of the equipment technology, it is adaptable to all applications described in the DVGW worksheet W 624. It meets both the requirements of the Drinking Water Ordinance and the Biocidal Product Regulation .
