Informational. Discuss Real Time Information to Improve Treatment Process Performance by Sentry Water Tech.
Critical Carbon Content (CCC) which will help track BOD and COD on a real time basis using an online SCADA system, with a probe that gets into the water. $4,900 for 6 month service piloting this new technology.
The biochemical oxygen demand (BOD) represents the amount of dissolved oxygen (DO) consumed by biological organisms when they decompose organic matter in water. The chemical oxygen demand (COD) is the amount of oxygen consumed when the water sample is chemically oxidized.

Background and Discussion/Report
Sentry Water Tech reached out to SAM to provide real-time information to the facility operations staff that is not available through any other sensor system to improve treatment process performance.
Sentry is a bioelectrode sensor platform and is a living biological sensor which reacts to changes in environmental conditions in real time. The sensor generates electricity as carbon compounds are reduced.
It measures the Carbon Consumption Rate which is the electron flow from the breaking of chemical bonds. This represents the amount of carbonaceous food being consumed by the bio film and can be related to the Chemical Oxygen (COD) demand which the plant measures to improve the treatment process performance.
SAM is presently doing a 6-month pilot service and has installed the Sentry unit.
A representative from Sentry will be making a presentation at the board meeting.
