Lutz-Jesco to Present New Chlorine Dioxide Water Disinfection System at IFAT 2024 (Munich, 13-17th June)

You don't always need dosing pumps in waterworks or the beverage and other process industries—that's the message from Lutz-Jesco following the launch of the EASYZON L chlorine dioxide solution which uses a reactor under vacuum conditions to mix chemicals.

The technology reduces the complexity of the system whilst providing several advantages.

By reducing maintenance requirements and the risk of outages and chemical leaks, it increases the safety of the entire process.

Consisting of a reactor mounted in a protective cabinet, the new EASYZON L chlorine dioxide system deploys our tried-and-tested acid-chlorite procedure with commercially available chemicals such as 9 per cent hydrochloric acid and 7.5 per cent sodium chlorite.

The system takes the chemicals from two storage tanks and mixes them in the correct ratio in the reaction tank, to form chlorine dioxide.

This reaction takes around ten to 15 minutes.

After the chlorine dioxide has been diluted with water, the system then feeds the resulting 0.05 to 0.15 per cent aqueous chlorine dioxide solution into a product tank, from where it is fed into the process by a dosing pump.

“Despite its compact design, the EASYZON L provides a maximum production capacity of 40 grammes of chlorine dioxide per hour, which corresponds to around 27 litres of chlorine dioxide solution," says Steffen Roth, Head of Development at Lutz-Jesco GmbH. “The chlorine dioxide system is ideally suited to the disinfection of drinking water in a range of contexts such as small waterworks, hospitals, hotels and the beverage industry.”

A feature of EASYZON L is vacuum mixing of chemicals without the use of dosing pumps.

The system generates a vacuum to draw in the hydrochloric acid and sodium chlorite.

The liquids are drawn in by a Venturi ejector.

Roth explains: "This approach not only enables precise mixing but also reduces the complexity of the system, thereby reducing costs, maintenance requirements and the risk of outages.

"The vacuum procedure also minimizes the safety risk.

Working under low pressure, it reduces the likelihood of leaks and uncontrolled pressure increases that result from defective dosing pumps.

"The flow sensors for chemicals and water incorporated in EASYZON L enable especially precise monitoring of the mixing process.

Many commercially available systems only measure the strokes of the dosing pumps, which is often less accurate."

According to the company, EASYZON L enables efficient disinfection of drinking water.

Despite its low concentration, the solution is effective against a wide range of micro-organisms, including bacteria, viruses, fungi and protozoa.

High stability over a wide pH range from five to 11 ensures reliability in various applications.

Moreover, chlorine dioxide forms fewer by-products during the disinfection process in comparison with chlorine and leaves no unpleasant odours or tastes.

The new chlorine dioxide system can be seen for the first time at IFAT 2024 in Munich from 13 to 17 June (Lutz-Jesco will be exhibiting at stand B1.220).
