If the limit value for Legionella of 100CFU per 100ml test water specified in the Drinking Water Regulation is exceeded, the owner or the operator of the building is obliged to commission the necessary measures, e.g. basic disinfection, hazard analysis and remediation plan. Old, sometimes even relatively new sanitary facilities then have to be renovated; pipelines including fittings, boilers, hot water storage tanks and distributors in the entire building have to be adapted or renewed. This renovation according to German DVGW guidelines can take years.
Compact unit for on-site production and dosing of NaClO solution for shock or long-term disinfection.
Fulfillment of the law
Our disinfection agents and processes are effective, approved and sustainable.
Biofilm providing sustenance and a hiding place
Legionella feed on biofilms in hot and cold water pipes. This biofilm is the best protection against chemical and thermal disinfection for Legionella. In order to achieve effective Legionella control, it is necessary to work against the biofilm in pipelines.
With its unique compact electrolysis system - nt-BlueBox - Newtec 's solution provides an "immediate aid" to the contaminated sanitary system by the means of shock disinfection. It is a short-term measure dosing high concentration active disinfectants against Legionella and Biofilms. All taps and showers in the entire house must be closed for at least one day.
But many water connections in buildings and residential units cannot be blocked or flushed for so long due to usage or access. In such cases, with a slightly increased concentration of NaClO solution produced, nt-BlueBox can additionally disinfect the sanitation system for an approved period of time in "justified cases" in accordance with the Drinking Water Ordinance without blocking the use of water in the building.
To monitor the Biofilm growth after shock disinfection, Newtec has developed an online monitoring and it has been in use for many years. In combination, the nt-BlueBox is used for disinfection whenever necessary in warm and cold water. The dosed NaClO concentration in the water is permitted in the Drinking Water Ordinance. In addition to the effect against Biofilms, millions of Legionellae freed from Biofilms and unicellular organisms have been proven to be quickly killed.
Cooling towers and Spray humidifiers
Our nt-BlueBox is also used in cooling towers and spray humidifiers against Legionella, biofilms and other microbiological pollution.
Prevent and Disinfection
Newtec is your counterpart for effective Legionella control.
Prevention is even more important than a forced shock disinfection in case the sanitary facility is already contaminated or has to be blocked. We have a sustainable integrated solution to prevent and kill dangerous bacteria in your sanitary systems in the long term.
We are looking forward to your contact!
