Modeling H2S in InfoSWMM, ICM and InfoSewer

Subject:   Modeling H2S in InfoSWMM, ICM and InfoSewer

You can model Sulfide in InfoSWMM/ICM and InfoSewer using the H2S water quality modeling option which uses BOD5 loading at nodes to estimate the  S concentration in the nodes and links of the network using constant network parameters for: 
1.       The Reaction Rate Coefficient,
2.       The Sulfide Loss Coefficient,
3.       Sulfide Flux Coefficient,
4.       Temperature in Degrees C,
5.       Soluble Sulfide Percentage,
6.       pH for the whole network, and
7.       The Ionization Constant.

Relationship between BOD5 and EBOD


Figue 1.  The concentation  of H2S and BOD5 can be graphed at each node and link.
