About MicroC™ Premium Carbon Sources
MicroC™ and MicroCg™ are proprietary products developed by EOSi specifically for use as an electron donor/carbon source in wastewater denitrification. EOSi technical staff helps customers to implement and optimize the usage of these products within their plants. The MicroC™ line of products has been engineered to overcome the key limitations of methanol and other carbon sources, including:

• Improved Safety: MicroCg™ is a completely nonflammable, nontoxic and 100% green product, composed entirely of renewable components.
• Quality and Consistency: MicroC™ products are manufactured to stringent quality specifications.
• Environmental Sustainability: MicroC™ products are manufactured from abundant and renewable agricultural raw materials.
• Price Stability and Cost Effectiveness: MicroC™ products have historically avoided the price fluctuations of other chemicals. They offer an economical means of reducing nitrogen load and the potential to circumvent or scale back costly nitrogen-removal upgrades to comply with increasingly stringent regulatory requirements.
• Improved Performance: MicroC™ enables faster denitrification startup and recovery periods, and improved performance in colder temperatures.
