The disinfectant and preservative DEXDA ® Complete for (drinking) water contains the active ingredients sodium hypochlorite and silver. The sodium hypochlorite quickly combats microorganisms/pathogens such as viruses, germs, fungi, bacteria and disinfects the (drinking) water within a few minutes. The silver, in the form of its free silver ions (Ag + ), has an excellent long-term effect and preserves the water for up to 6 months. DEXDA ® Complete can be used in almost all areas of water treatment.
Depending on the application, fluid (water)-carrying systems must be cleaned or disinfected at regular intervals, otherwise microorganisms will multiply and biofilm will form. Biofilm formation is influenced by several factors: bioavailable nutrients for microorganisms, surface properties of water-contacting materials, temperature and flow conditions.
DEXDA ® Complete is dosed as required from the respective container into the water/drinking water to be treated. The different container sizes result in a wide variety of areas of application and dosing variants. Depending on the application, the use of dosing pumps/devices is recommended for needs-based dosing.

According to §11 of the current German Drinking Water Ordinance (TrinkwV), the dosage of the active ingredient sodium hypochlorite is 1.2 mg per liter (5.1 mg/l) approved for the disinfection of drinking water (based on free Cl2) if no other disinfection can be guaranteed. After processing, a residual concentration of 0.1 – 0.3 mg per liter (0.6 mg/l) remain in the disinfected water. According to Section 11 of the German Drinking Water Ordinance, silver is no longer included in the UBA’s current list. This does not affect use outside of the public water utility.
DEXDA ® Complete has a shelf life of 3 years when stored in a cool place, protected from sunlight, upright and closed.
