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.
Typical Life Forms in the Treatment Stages
Initial Stages – Rapid Growth, Abundance of Food, Lower Life Forms
Middle Stages – Less Food, Higher Life Forms Grow
Latter Stages – Minimal Food, Highest Life Forms
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 System Configurations
The number of treatment stages and most efficient layout of the system is created within the tank / basin (new or existing) with baffled walls to ensure a plug flow condition. The system can be designed to meet pretreatment, secondary and nutrient removal treatment objectives.
The Design Request Questionnaire provides our engineers with information for evaluation of the application, performance requirements and solution recommendation.
|Treatment Objective||Treatment Stages|
|Organic (cBOD) Removal||2 or More|
|Ammonia (NH3-N) Removal, Nitrification||2 or More|
|Total Nitrogen Removal, Denitrification||2 or More + Anoxic Stages|
|Sludge Minimization Objective||Treatment Stages|
|Reduction of Biological Sludge Production||8 to 12|
Systems with 8 to 12 treatment stages assure the development of a highly efficient microbial food chain resulting in low biological sludge yield.
What happens to the sludge?
- Mass/Energy is neither created nor destroyed…Law of Conservation of Mass, First Law of Thermodynamics.
- Mass/Energy is Converted to other forms.
- Mathematically modeled concentrations of contaminants in each treatment stage decreases according to first order kinetics.
This benefit is specific to the proprietary Nebula® MultiStage Biofilm System resulting in lower sludge handling, storage and disposal costs.
The Nebula® MultiStage Biofilm System is a simple solution for biodegradable wastewater applications.
