BPO specialize in carrying out assessments of wastewater treatment plants and identifying areas for improvement. We are experienced in assessing anaerobic, activated sludge and pond systems.

As part of our troubleshooting service, a BPO wastewater treatment specialist will visit your site to perform system audits. These audits include a review of operator training, data collection and analysis, sampling and testing, and sessions with plant operations staff to discuss current performance of the treatment plant and provide recommendations for improvement.  A site report is prepared following the visit that includes an analysis of the data collected, along with possible process recommendations.
