Updated database regarding new references, stormwater concentrations, reduction efficiencies and concentrations for overflow water
There is now an updated version of StormTac’s database with a lot of new data from a large number of new references. Several sheets have been updated with new data, which means a larger basis for the development of new typical concentrations for stormwater, treatment effects and concentrations for overflow water. The work of producing new typical concentrations and treatment effects from this data is in progress. Recently, the typical concentrations of TBT and the treatment effect of phosphorus (P) from ponds were changed. More changes are planned in the near future, first regarding irreducible (minimum possible outlet) concentrations and typical concentrations for different land uses.
