Water and Wastewater Treatment Engineer

Freese and Nichols engineer Leonard Ripley is one of just eight experts selected to participate in a national anaerobic treatment workshop.

The National Science Foundation funded workshop’s purpose is to advance understanding and promote implementation of anaerobic co-digestion at wastewater treatment plants. Co-digestion is the addition of high-strength waste streams, typically industrial or food processing residuals, to municipal anaerobic digesters to boost their energy production. 

Those invited will talk about best practices for water resource recovery facilities based on their areas of expertise.  

Ripley has experience in anaerobic digestion and co-digestion at several municipal facilities, most recently with the cities of Wichita Falls and Fort Worth.

The findings from the workshop will help form a Framework of Practice to be published by the Water Environment & Reuse Foundation and the Water Research Foundation.

The workshop will be Oct. 25-26 in Alexandria, Virginia.
