DEXDA® Clean

- broad spectrum disinfectant: bactericidal, virucidal, algicidal and sporicidal
- deodorant properties, ie smells and flavors in the water, eg from phenols, algae or their decomposition products are converted or not produced at all
- degradation of organic or microbiological deposits in water-bearing systems (biofilm degradation)
- no formation of halogenated substances such as trihalogen compounds (trihalomethanes, THM’s), chlorophenols, AOX compounds and chloramines in drinking water
- 25x stronger than hydrogen peroxide (active oxygen)
- good material compatibility due to almost pH-neutral application

DISINFECTION CONCENTRATE WITH HIGHLY EFFECTIVE EFFECT

The disinfectant concentrate DEXDA® Clean (Pro) for disinfection and biofilm removal in water-bearing systems is a 2-component chlorine dioxide solution and, after activation, contains the active ingredient chlorine dioxide, which is approved according to the current Drinking Water Ordinance (TrinkwV). DEXDA® Clean (Pro) is a highly effective and broad-spectrum disinfectant. It has a bactericidal, virucidal, algicidal, sporicidal effect and, depending on the concentration, breaks down biofilms in the short and long term.

Challenge of water hygiene

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.

Application

The product is activated as needed from the two components A (liquid) and B (tablet/powder). After 3 hours, a pure, highly effective concentrate solution of 0.3% chlorine dioxide is created. Due to different container sizes, DEXDA ® Clean (Pro) offers a wide range of applications and dosing options.

Dosing examples	Dosing quantity per cubic metre of water	Concentration in the water
Disinfection of water distribution systems	2 litres	6mg/l
Biofilm removal/ shock disinfection Pipe rehabilitation	6 litres 8 litres	18mg/l 24mg/l

According to §11 of the current Drinking Water Ordinance (TrinkwV), the dosage of the active ingredient chlorine dioxide of 0.05 – 0.4mg per liter is approved for the disinfection of drinking water. After treatment, a residual concentration of 0.05 – 0.2mg per liter should remain in the disinfected water. Accordingly, no costly and time-consuming multiple flushes are necessary after the disinfection of water-bearing systems. To monitor the application or residual concentration, we recommend chlorine dioxide quick tests.
