Reports:
Ryan Stringer:
- At M.C. Stiles Wastewater Treatment Plant there is a pre disinfection sensor issue
- Compressor issues due to cold weather. Condensation. They have been pulling compressors back to the office to do maintenance. Soon annual maintenance will come up, with full rebuild kits.
- At Maxson influent at splitter box, the sensor is passing function checks. There are drops in measurements that correlate with cleaning:
- More stringy material is getting stuck in the carbolizer
- Maxson post disinfection has a sample pump on order. There is a Con::Cube issue
- Con::Cube and probe are passing function checks, but the compressor is not effective at cleaning.
- Maxson Pre-Disinfection:
- Hach analyzer vs Hach probe - the analyzer includes reagent #reagent #analyzer
- All Evonik signals are coming into the Emerson Ovation System
- Working on calibration for grit tank accuracy
- Compressor issues for BOD and COD at grit tank - the screens can get contaminated when they're not being blown out regularly. A piece of grit got jammed into a piece of equipment.
- Stiles Pre-Disinfection BOD and COD
- Stiles Pre-Disinfection TSS and Temp
- Stiles Post-Disinfection BOD and COD
- Stiles Post-Disinfection TSS and Temp
- Next Steps for Tioga (Ryan and Spencer)
John Abrera:
- BOD is typically a subset of COD
Don Hudgins:
- Something hit the plant hard from February 2 to Feb 7 - asked Derek Willis to investigate industry
Peter Gabor:
- Great report of Ovation gaps and improvements - a lot of disinfection sensors are bonked.
- Radio spec
- EDS Portal opportunities
