CHLORINSITU IIa is a compact on-site electrolysis system for the production of a low-chlorate hypochlorite solution from sodium chloride and electrical energy. A key advantage is its simple process management and excellent system safety through integrated ventilation and bleeding.

The vacuum controller DULCO^®Vaq CGVa meters chlorine gas cost-effectively and efficiently. Maximum possible operating safety and reliability is ensured by the use of high-quality materials, such as tantalum and silver.

The motorised control valve for chlorine gas DULCO^®Vaq type PM 3531 ensures precise electronically controlled metering of the chlorine gas flow. The linear control characteristic is guaranteed by an externally controlled step motor.

Vacuum switches DULCO^®Vaq PM 400 and 440 automatically and reliably switch between two chlorine gas storage tanks. They therefore ensure an uninterrupted chlorine gas supply, even if a chlorine gas storage tank becomes empty.

Injectors for chlorine gas, series DULCO^®Vaq, generate a stable vacuum even at high operating pressures.

Sarah Köhler crawls towards her dream: her first Olympic medal. She wins bronze in the 1,500-metre freestyle at the Olympic Games in Tokyo and thus wins the first German medal in pool swimming for 13 years.

When metering liquids, gas bubbles and pressure fluctuations are the main causes of metering inaccuracies. Outgassing media can also block the conveying process completely. Intelligent functions and model-based control behaviour of the gamma/ X and XL solenoid-driven diaphragm metering pumps provide a remedy.

ProMinent is expanding its product range with new sensors for measuring peracetic acid (PAA) and hydrogen peroxide (H₂O₂) without cross-sensitivity to one another. The measured variables are recorded selectively – without measurement falsification, even at low concentrations.

Cleaning dirty water from households is a responsible and complex task. Waterworks Frankfurt on Main, Germany, therefore relies on reliable products such as the DULCODOS SAFE-IBC dosing system, for the disinfection of filter systems.

In the Flanders region, more than 83% of the wastewater is treated using the most modern methods. The project has a positive effect on the water quality of the Schelde and Maas and makes a significant contribution to keeping the North Sea clean. Aquafin, which was founded by the Flemish government around 30 years ago, plays a key role in this.

When Prof. Dr. Viktor Dulger dared to take the step into independence in 1960, no one could have guessed what would come of it. From the foundations built 60 years ago, the ProMinent Group has developed into one of the world's leading manufacturers in the field of dosing technology and water disinfection.

In the fight against the corona virus, researchers are working against time: a vaccine must be developed, tested and approved as quickly as possible. For this reason, one of the world's largest service providers for medical research contacted ProMinent to optimise special metering tasks.

The effective disinfection of surfaces plays the central role in the containment of the corona virus. With our electrolysis systems, the highly effective disinfectant can be produced directly on site. The North Italian civil defence is already benefiting from this.

To combat the spread of the coronavirus in the Chinese city of Wuhan, several temporary hospitals were built in a very short time. ProMinent China donated two chlorine dioxide systems for water treatment for one of them.
