Plug-and-play emergency chlorination for greater drinking water safety

Lutz-Jesco presents mobile emergency chlorination system SAFETYCHLORMIX for waterworks at the Tausendwasser 2025 trade fair in Berlin

Wertheim, February 10, 2025 - What happens when permanently installed disinfection systems in waterworks reach their limits? Lutz-Jesco has developed the "Safety Mix" mobile emergency chlorination system for these emergencies. The system can be seen from March 26 to 27 at the Tausendwasser 2025 water industry trade fair in Berlin (stand: 7.BP.29). The company will also be presenting the new VakuStop safety shut-off valve, which makes handling hazardous chlorine gas safer.

If the bacterial count in drinking water rises - for example due to contamination caused by heavy rainfall that has washed soil into a spring catchment - waterworks must react quickly to avert a health hazard for thousands of households. It becomes critical when the contamination occurs in an intermediate storage tank, for example, and the permanently installed, stationary disinfection systems cannot do anything. "We have developed the SAFETYCHLORMIX for such cases," says Cristian Meyer, expert in drinking water technology at Lutz-Jesco. "With this mobile dosing system, waterworks can quickly and effectively bring contamination under control by precisely dosing liquid chlorine." The emergency chlorination system has already been purchased by several municipal utilities in large cities such as Schwerin. It is not only used in waterworks, but also for other special challenges relating to the safety of drinking water - such as legionella contamination in the water supply of a high-rise building. "There is currently no comparable system on the market."

A single person can conveniently pull the system to the place of use

Lutz-Jesco offers the SAFETYCHLORMIX as a plug-and-play system that is mounted on a robust tubular steel trolley ready for operation. This means that a single person can easily pull the system to the site and start emergency chlorination immediately. At the heart of the system is the Magdos LDp diaphragm dosing pump, which injects a calcium hypochlorite solution from a container into the contaminated water via a ten-meter-long PVC hose. The chemical releases hypochlorous acid (HOCI), which kills microorganisms through oxidation. "The pump impresses with its exceptional robustness, reliability and ease of maintenance," explains Meyer. "Thanks to its magnetic drive, it requires no wearing parts such as gears or shafts."

SAFETYCHLORMIX enables chlorine production of up to 650 g/h

The SAFETYCHLORMIX is available in different performance levels, which enable chlorine production of 18 to 650 g/h. The flow rate varies between 0.5 l/h and 15 l/h. There are also two container sizes available for the chlorine granulate, with a volume of 25 or 60 liters. To increase safety, the system is equipped with a pressure maintenance valve that regulates the line pressure and an overflow valve that prevents overpressure. A polyethylene drip tray provides additional protection by collecting any escaping liquids, preventing chemicals from escaping into the environment in an uncontrolled manner.

Also on show at Tausendwasser 2025: New safety shut-off valve makes handling chlorine gas safer

At Tausendwasser 2025, Lutz-Jesco will also be presenting the new VakuStop, a safety shut-off valve combined with a vacuum regulator that enables waterworks to handle chlorine gas cylinders more safely. Users can mount the VakuStop on the valve of a gas cylinder in just a few simple steps and connect it to a gas warning device. In the rest position, an electromagnet then holds the valve open so that chlorine gas can flow. If there is a chlorine alarm, a cable break, overpressure is detected or the pushbutton on the device is pressed, the power supply is interrupted so that the valve closes immediately and the gas leakage is interrupted.

Lutz-Jesco also offers a complete safety system to increase the safety of larger chlorine gas systems. The core element is a control unit that connects a gas warning device with up to twelve safety shut-off valves. In the event of a chlorine alarm, the control unit can close all valves simultaneously. "With the VakuStop and our safety system, we are helping waterworks to sustainably optimize safety when handling chlorine gas and reduce potential risks to a minimum," says Meyer. Such safety systems are important because handling the chemical poses considerable health risks - from eye irritation to fatal pulmonary oedema.
