Dear All ,
Kindly i have a question , and i am a little bit confused about H2s Calculations in sewer gems.
First Of all i have seen this article and it understand it well :
Modeling septicity / hydrogen sulfide (H2S) .
In this article i understand that SewerGems uses Pomeroy Parkhurst Equation to predict H2S formation
Then i want to verify if that formula is really used inside the Sewer-gems . what i did is make a simple model consist of 1 line only and compare the result from sewer-gems with result from excel sheet using Pomeroy Parkhurst Equation .
Result from model is shown below and data from model is shown below
The Sewergem model based on the above data give me a H2s result = 0.16487 mg/l
using excel sheet and applying Pomeroy Parkhurst Equation on the above data that i get from sewer gems , then unforuntly i did not get the same result !!!?
is there is some thing wrong inside sewer-gems programming , is sewer gems does not use the same formula or did i make a mistake ?
this is the result from the excel sheet i get H2S = 0.1114 mg/l
Sewergems model is here
