Air Stripper Off-Gas Air Dispersion Modeling
Mundell’s client was concerned that the off-gas from an air stripper stack would be an odor nuisance to their employees. Mundell performed air dispersion modeling to demonstrate off-gas concentrations would remain below the odor threshold……Read More »
PLC Control Program Alteration
The operation of a remediation system was observed to be inefficient. The system’s logic program was actually damaging the equipment. The PLC control program for the system was written in such a way that when an alarm condition was detected, the system shut down for 10 minutes and then reset itself instead of remaining idle until manually reset by an O&M technician. Mundell wrote a new program to address these issues……Read More »
Remediation O&M – Efficient Cleaning of Airstrippers
Mundell transformed the all-day two person cleaning of airstrippers into an approximately 4 -hour one-person job using an acid re-circulation loop……Read More »
Groundwater Flow and Contaminant Transport Model Used to Evaluate Threat to Human Health and the Environment
Mundell undertook a modeling study at a site where the current remediation system had reached a point of diminishing returns to show that shutting off remediation would not result in further discharges……Read More »
