Computerised electrocoagulation for H2S control

Challenge:

Hydrogen sulphide (H2S) was at this time one of the key issues in wastewater discharge. H2S is highly toxic even at low concentrations and causes corrosion of concrete pipes and structures. At the same time, the concentration is expected to increase as the separation of wastewater and clean water becomes more widespread. At this day, overdosing of iron salts was typically used, which represents a significant expense for utilities.

Solution:

The project aimed to develop a sensor-controlled electrocoagulation as a cost-effective concept for reducing H2S in wastewater systems by oxidising iron plates.

By utilising renewable energy sources, the solution opened up a climate-friendly way to combat H2S.

Impact:
