NEBULA® MultiStage Biofilm Systems

Specialized design

The Nebula® MultiStage Biofilm System is a proprietary process developed for treatment of municipal and industrial wastewater. Treatment is achieved through spatial separation of microbial populations fixed to a media surface. Successive stages of biofilm media create separate microbial living conditions and food sources within the process resulting in a highly effective food chain. These food chains are responsible for meeting the specified treatment objectives.

High food to microorganism (F/M) ratios in the first stages of treatment create feast conditions, encouraging rapid growth of lower life forms. In the later stages – famine conditions – low F/M ratios favor higher life forms. When configured as a plug flow system with multiple stages, biological sludge can be reduced up to 80% compared to suspended growth technologies.

Biofilm Media can be added to an existing process to enhance removal efficiencies and achieve nitrification and denitrification.

Nebula® MultiStage Biofilm equipment design compliments our proprietary process design by providing:

  • Compact Footprint Due to Higher Surface Media Loading Rates
  • Simple Operation With No Internal Moving Parts
  • Incorporation of an Energy Efficient Diffused Aeration System
  • Controls and Monitoring Designed With the Operator in Mind
  • Reduced Sludge Handling. Storage and Disposal Costs
