Wastewater treatment plants use anaerobic digestion to generate heat and electricity on site. During anaerobic digestion, microorganisms break down organic materials from wastewater. The methane gas produced from this process is then used to generate heat and electricity that is used in plant operations.

What Benefits Will I Get?

Increased Return on Investment, Protection of expensive plant equipment (CHP’s) and Validation and optimization of the AD process

How Do I Do It?

Operators opt for fixed in line systems that will measure multiple sample point to ensure the process verification is monitored. These systems connect via industry standard protocols to the operators control systems housed on site. Portable analyzers offer flexibility for process monitoring at various points in the AD process to ensure maximum efficiency of the site.

Why Monitor and Analyze the Gas I Produce?

The composition of biogas is crucial. The most abundant component in biogas is methane, which typically makes up 50% to 60% of the gas. To verify the anaerobic conditions in their system, biogas operators analyze their gas for oxygen content, this ensures the process produces maximum levels of methane to increase energy production. It is also important to monitor for levels of gases harmful to the plant equipment such as hydrogen sulfide.
