Activated Sludge Operations Webinar - October 28, 30, November 4, 6
The webinar (multiple 2-hr sessions - 2 sessions first 3 days, 1 session on last day) is structured for operators and managers of activated sludge plants. It is operations oriented providing practical information to use in day-to-day operations. Participants will receive an operations manual for activated sludge treatment systems. This will be presented over 7 sessions spread out over 4 days to cover all of the material. CEUs are awarded (1.4). On-demand recordings can be made available in case sessions(s) ar emitted due to work or other conflicts.Most popular related searches
