The most economic disinfectant is available as gaseous or liquid chlorine supplied in cylinders or ton containers. Using a remote vacuum operated gas feeder, a chlorine solution is prepared on site from chlorine gas and water. This solution is used as a disinfectant.
Siemens Water Technologies' chlorinators operate using the all-vacuum principle, which means that there is a vacuum from the cylinder up to the injector. All of the gas feeders are based on the worldwide proven V-notch flow control technology which provides a wide control range and very high repeatability. Control of the gas feed rate can be adjusted manually or automatically via an electric positioned.
The full vacuum gas feeder and our other models can also be used for metering carbon dioxide (CO2) for lowering the pH, and for hardwater conditions of potable water. The full vacuum gas feeders are also suitable for sulphur dioxide (SO2) for dechlorination applications, and for ammonia (NH3).
