Municipal and industrial wastewater facilities monitor dissolved oxygen (DO) concentrations to ensure the treatment process is operating properly which includes the health and performance of the wastewater biology and efficient use of treatment chemicals and energy. Continuously monitoring DO in wastewater treatment ensures optimal oxygenation in activated sludge and biological nutrient removal (BNR) processes without inefficiently over-aerating. Facilities are required to pretreat their outgoing wastewater and submit biological oxygen demand (BOD) data on a regular basis to meet regulatory or compliance requirements. AlpHa has sensor solutions uniquely tailored to each application, including continuous (process) monitoring sensors, DO and BOD laboratory electrodes, and handheld DO meter solutions.
