Denver-Area WWTP Migrates from Methanol to EOSi’s MicroC® 2000

A central Colorado wastewater treatment facility concerned with their continued use of methanol as a supplementary carbon source embarked on a test program to investigate using non-hazardous and less costly alternatives.

In addition to methanol’s inherent safety and toxicity risks and unstable price-fluctuation issues, using methanol as a supplementary carbon source also typically involves expensive infrastructure and equipment investment, strict regulatory requirements, significant environmental impact, unique bioengineering challenges, lower carbon efficiency, and more.

Research indicated many previous attempts to use non-methanol carbon sources in down flow denitrification filters similar to that used at the Colorado facility failed to consider the down flow filter operation itself may require modification because of differences in yield and kinetic characteristics of alternative carbon sources relative to methanol.
