OVERVIEW
- Automatic control of air supply by a combination of PI-control and a major FuzzyLogic
- Control range in automatic mode between 0 – 1 % O2 in dependence of measured H2S-concentration (shut down limit: 2,4 % O2)
- Individual control of several digesters
- AwiDESULF’s advantages:
- process stability
- minimal operational cost
- regular measuring and O2-monitoring
- exact control even at fluctuations of produced gas
- remote maintenance
- Certified for the North American market (UL /CSA)
