MicroC™ Premium Carbon Sources vs. Other Products
Methanol is currently the most widely used electron donor/carbon source for wastewater denitrification. MicroC™ Premium Carbon Sources offer a highly attractive alternative to hazardous, increasingly costly and energy-intensive methanol.
Safety
Methanol is highly flammable and toxic, jeopardizing the health and safety of treatment plant personnel, facility users and nearby communities. Recent incidents including the explosion of the methanol tank at the Daytona Beach, Florida wastewater treatment plant highlight safety issues associated with methanol. MicroC™ Premium Carbon Sources are safer alternatives to methanol.

Cost Effectiveness
MicroC™ Premium Carbon Sources have several economic advantages over methanol and other electron donor/carbon sources and can result in significantly reduced operational and capital expenditures
- More efficient electron donor/carbon source optimized for denitrification that can result in considerable savings (see case studies)
- Potential reduction in safety-related expenditures including insurance premiums,
training, regulatory compliance, etc. (see CDM Capital Study

Environmental Sustainability
MicroC™ Premium Carbon Sources are derived from renewable resources that are abundant in the United States. Every gallon of MicroC™ Premium Carbon Sources used (instead of methanol) saves the energy equivalent of heating 0.5 US households per day or providing electricity for 0.7 US households per day.
