OnlineH2S includes a microcontroller-unit for a quantitative determination of the released H2S from the sewer with sensor technology at two or more selected measurement points. It serves as the basis for H2S-adapted regulation of chemicals for water treatment in sewage systems.
The H2S-measurement works with selective electrochemical sensors. The mobile microcontroller includes a data acquisition and data transmission tool, digital and analogue input connections for various easurands as well as digital and analogue alarm output connections (4 – 20 mA) for controlling of dosing pumps for treatment-chemicals, valves etc.
Data can be downloaded by a secured internet transfer line at any time. The control-algorithm includes an intelligent self-learning system of settings, which reacts immediately to local circumstances of the sewage-volume and H2S-carriage.
By evaluating those information, an optimal dosing-value will be determined automatically that will be used for the water treatment with chemicals in the sewage system.
