Romania’s need to expand its water infrastructure is also bringing the microbiological safety of drinking water across long distribution networks to the fore. According to Romania’s National Institute of Statistics, 77.6 percent of the population was connected to the public water network in 2024.
The OECD states that the country needs to more than double its current annual investment in water and sanitation to comply with EU water directives and improve system efficiency.
Drinking water disinfection with chlorine gas
In a statement issued by the company, Lutz-Jesco Sales Manager Michael Raabe said chlorine gas remains an economical option, particularly for disinfecting large volumes of drinking water.
According to Raabe, the main advantages of the method include its use at low concentrations, precise dosing and the ability to maintain a residual chlorine level in the distribution network.
Chlorination has been one of the methods used for drinking water disinfection since the early 20th century. However, dosage, contact time, pH, temperature and water characteristics need to be controlled.
Chlorine gas dosing system operating on the vacuum principle
At ExpoApa 2026, Lutz-Jesco will exhibit a chlorine gas dosing system described as a “chlorine wall”. The system operates on the vacuum principle to reduce the risk of uncontrolled gas leaks.
Ejectors using the Venturi principle create negative pressure, drawing chlorine gas from the cylinder and transferring it into the water. A booster pump provides the necessary motive water, while the amount of chlorine dosed is regulated via a control valve.
The system can be managed via a central PLC or with a TOPAX controller integrated into the EASYPRO water sampling station.
Precise dosing with Memdos Smart LPX
Another solution the company will exhibit at the fair is the Memdos Smart LPX diaphragm dosing pump.
According to Lutz-Jesco, the microprocessor-controlled system allows the diaphragm to operate at different speeds during the suction and discharge phases. The aim is to achieve a lower-pulsation, more even flow. The company states the pump’s repeatable dosing accuracy as ±1 percent.
ExpoApa 2026 to be held in Bucharest
Organised by the Romanian Water Association, ExpoApa 2026 will take place on 8-10 September 2026 at the ROMEXPO exhibition centre in Bucharest. At the event, Lutz-Jesco will present its solutions for drinking water and water treatment applications to industry professionals.
