Johnson Controls experiences recent innovations in continuous gas monitoring technology at Back River Waste Plant in Baltimore

The Back River Wastewater Treatment Plant in Baltimore has installed Qualvista siloxanes monitoring at its plants in October, 2017. The Baltimore City plant has an existing cogeneration facility with Johnson Controls, built under an energy savings performance contract. Qualvista was chosen to install its monitoring system onsite the Back River facility.  The system can measure “in situ” siloxane, methane, hydrogen sulfide, carbon dioxide and oxygen from up to three sample points with a single monitor.

The Back River plant serves more than 1.3 million residents in the Baltimore City and County and treats 180 million gallons per day of wastewater. Its cogeneration facility is estimated to reduce the purchase of electrical power by $1.4 million annually effectively using the methane gas produced at the WWTP.

Tim Robinson, Qualvista US sales consultant, has been guiding the Back River project and is pleased with the results: “This is one of the first installations in the US and the whole team is just extremely happy to see such a success.  We have seen the additional data available from near real results allows us to localize and attribute performance issues to the root cause.  Grab sampling was not allowing us to understand how the system was performing, it only allowed us to get periodic snapshots of the conditions over many months.  We also found grab sampling was unreliable as it often reflected the sampling process itself as much as the real condition of the gas being tested.  This is a significant improvement.”
