Renewable energy from biogas

Ultrasonic technology helps City of Charlotte pursue increased energy from renewable biogas

The City of Charlotte, NC employs five strategically located wastewater treatment plants to support over 818,000 customers. The City embarked upon an ambitious plan to generate up to 15% of its largest plant’s electrical power needs from a renewable and essentially free biogas energy source. With Endress+Hauser's ultrasonic technology, the Proline Prosonic Flow B 200, the City was able to pursue increased energy from renewable biogas.

The results

  • Increased energy from renewable biogas

  • Reliable data for safe and efficient operation

  • Added revenue from combustion of biogas to generate energy from renewable resource

  • Reduced maintenance and labor costs

Customer challenge

Measuring the flow and methane content of biogas was difficult and expensive in the past. The City uses biogas energy on a small scale for process heating but remaining biogas must be burned through flaring which is more safe and environmentally friendly. In its first Combined Heat & Power project, the City planned to use as much of this energy source as possible, but final design and financial justification obstacles had to be addressed first.

Our solution

With Endress+Hauser's Proline Prosonic Flow B 200, the City was able to pursue increased energy from renewable biogas. The B 200 provided continuous monitoring of the City's anaerobic digester gas, providing reliable data for the safe and efficient operation of individual digesters and the downstream combustion process. Additional revenue can be earned from the combustion of biogas, generating electrical energy from this renewable resource.
