The frequent lending of standpipes for different purposes such as the construction water supply or the drinking water supply in markets and festivals, causes the standpipe and its components such as system separator and water meter to get in contact in different places with different types of water.
Often, contamination occur due to different situations:
- permanent construction, use, dismantling
- temperature fluctuations
- running over the pipes
- improper installation and use
- lack of expertise of users
Proper cleaning before and after use and proper storage are mandatory. These measures are indispensable for mobile equipment companies to protect human health and drinking water quality.
Standards & regulations
DVGW worksheet W408-B1
According to this rule, the cleaning of the standpipes and removal devices by drinking water with a sufficiently high flow rate is normally sufficient. In case of severe contamination it must be disinfected.
DIN EN 806-4
According to DIN EN 806-4, only disinfectants which are specified in the national or European standards for the corresponding purpose of use may be used.
DVGW worksheet W201
The worksheet describes the common disinfectant chemicals for system disinfection. Among other things, substances such as hydrogen peroxide, chlorine dioxide or sodium hypochlorite can be found here.
List of the Federal Environmental Agency
The list of treatment substances and disinfection procedures published by the Federal Environmental Agency in accordance with § 11 of the Drinking Water Ordinance contains a list of the treatment substances that may be used to disinfect the water itself. Here you can find substances such as calcium hypochlorite, chlorine and again sodium hypochlorite.
Disinfectants and procedures
The DVGW worksheet W291 describes the usual disinfection chemicals for plant disposal. Here you will find, among others, the following substances:
- hydrogen peroxide
- potassium permanganate
- sodium hypochlorite
- calcium hypochlorite
- chlorine dioxide
The list of treatment substances and disinfection procedures published by the Federal Environment Agency in accordance with § 11 of the Drinking Water Ordinance contains a list of the treatment substances that may be used to disinfect the water itself:
- chlorine dioxide
- sodium hypochlorite
Sodium hypochlorite is a substance which may be used both for the disinfection of plants and for the disinfection of (drinking) water.
The BEULCO Clean disinfectant is a sodium hypochlorite-based agent. Why do we use this remedy?
Sustainability and quality are very important to us. Our disinfectant is absolutely harmless, ecological and degrades by 100% again. In addition, with our disinfectant and process, we can greatly reduce your time and effort.
BEULCO Disinfection Devices and Systems
- Cleaning and disinfecting by rinsing the standpipe: Dirt and germs are flushed out directly
- 3ml / liter of the product are added to the water via a pump
- Disinfecting effect can be read directly via the redox value (proven germ-free)
- Disinfection usually after 6-10 minutes depending on environmental conditions
- No resistance formation (acts immediately, no dwell time in the standpipe)
- about 20 liters of water = disinfection of 20-40 standpipes
Disinfection with hydrogen peroxide-based disinfectant
- Disinfectant needs sufficient exposure time
- After disinfection, sufficient drinking water must be rinsed in order to remove any remainder of the agent (hydrogen peroxide is aggressive and can attack the material if left over during storage)
- After rinsing, the pH value must be measured: Only at a value of 7 is it ensured that the water is clean (but not whether the disinfectant's exposure time was sufficient to completely disinfect the standpipe)
- Per standpipe about 2 liters of the disinfectant are needed (filling quantity) (dilute solution = longer disinfection time)
The redox voltage [mV] is a measure of the germicidal and oxidative effect of disinfectants in water. The higher the redox value of the water, the lower the level of contamination. During the disinfection process, the valve is flushed until a redox value of 650mV-700mV is reached.
At this value, water and fittings have been proven to be germ-free. If the value is not reached, the disinfectant works until the last germ is killed and the voltage of 650-700mV is reached.
