Tech Talk Ep. 4 - Modelling of odour and corrosion in sewer networks
The rapidly expanding global population moving into new urban environments has brought along with it urban problems that require fast and effective solutions. In the fourth installment of our Tech Talk, Morten Kjølby, our senior project manager for urban water, presents how DHI’s software technology can simulate and predict hydrogen sulfide levels in sewer networks. This enables mitigation options to be formulated to facilitate optimal decision-making by cities’ authorities.
Formation of hydrogen sulfide (H₂S) in sewer systems cause serious odour and corrosive problems in cities all over the world. Toxic, the acid can result in a series of illnesses such as irritation of the eyes, nose and throat to the more serious respiratory tract infection and even death when inhaled in high concentrations.
An advanced modelling package developed using MIKE Powered by DHI’s software technology enables authorities and sewer management operators to predict the level as well as the formation of H₂S produced in sewage pipes. This provides them with full insight and understanding of the formation of the compound.
