3 Reasons to Use Thermal Mass Flow Meters in Wastewater Treatment

 In Sage Thermal Natural Gas Flow Meter

Engineers at various wastewater treatment plants (WWTP) recognize the benefits of using thermal mass flow meters to monitor aeration air flow rate, improve process efficiency, reduce energy costs, and measure digester gas.

1. Aeration Air Flow Rate

The activated sludge process is a conventional method in wastewater treatment, where wastewater is treated with aeration airflow. Here blower air is pumped and diffused evenly to oxygenate the aeration basins.

The oxygen feeds or nourishes microorganisms within the basin, so the bacteria thrive and consume suspended particulates. At various phases of the process, compressed air oxygenates, clarifies, filters, or disinfects. Compressed air is one of the most significant expenses associated with wastewater treatment.

2. Improve Efficiency and Reduce Cost

By monitoring and controlling airflow with thermal mass flow-meters, the facility maintains the proper environment for optimum bacteria growth to accomplish its objective and significantly reduces energy costs. Some facilities have reduced energy consumption by as much as 25%.

3. Measure Digester Gas

After bacteria have consumed the suspended particles, the solid matter is subsequently removed and enters a secondary process. Here, digesters breakdown the waste, creating digester gas that contains methane and carbon dioxide. The gas is further processed and used as renewable energy. Throughout this process, thermal mass flowmeters measure the measure mass flow of the digester gas and have an extremely low-end sensitivity to handle the low flow typical of digester gas.
