Thermal Flow Meters Improve Wastewater Gas Monitoring

Wastewater treatment plants (WWTPs) use large, heated digester tanks to remove and dispose of solid waste material. Here, bacteria break down the material, producing digester gas in the process. Methane is a primary component of anaerobic digester gas (ADG) and a large wastewater treatment plant can produce roughly one million cubic feet of this gas each day.

Most WWTPs utilize recovered gas to fuel boilers and flare off the excess. Other biogas uses include fuel for combustion engines to generate electricity, fuel for natural gas vehicles, and sale and distribution to neighbouring industries and communities.
