  • Sulfide emissions in sewer networks: focus on liquid to gas mass transfer coefficient

    H2S emission dynamics in sewers are conditioned by the mass transfer coefficient at the interface. This work aims at measuring the variation of the mass transfer coefficient with the hydraulic characteristics, with the objective of estimating H2S emission in gravity pipes, and collecting data to establish models independent of the system geometry. The ratio between the H2S and ...

  • What is Indoor Air Quality?

    Indoor Air Quality (IAQ) refers to the degree of air purity inside buildings that constitute the usual environment in which people carry out activities (offices, homes, schools, shopping and leisure centres, etc.) Because of increasing urbanisation and our contemporary lifestyle, most people spend a large proportion of their time in these closed environments. The high level of atmospheric ...
