NEBULA® MultiStage Biofilm Systems

    The Solution is Simple

    Biological treatment systems are available in a variety of process design configurations. From suspended growth to attached growth, the Nebula® MultiStage Biofilm System is designed to utilize microbiology in a smarter way. Flexible and efficient design configurations, simplistic operation and operational savings result in a low cost of ownership solution.

    Many experts agree, an attached growth biological process offers:

    • Compact Footprint
    • Simple Operation
    • Reduced Biological Solids Production
    • Tolerates Hydraulic and Organic Loading Variations
    • Eliminates or Reduces Biomass Recycling

    Process Design/Applications

    Our Process

    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.

    Ammonia (NH3-N) Removal, Nitrification2 or More
    Total Nitrogen Removal, Denitrification2 or More + Anoxic Stages
    Sludge Minimization ObjectiveTreatment Stages
    Reduction of Biological Sludge Production8 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. This proprietary process can be designed to meet the challenges of industrial and domestic wastewater.

    Where Process Design Meets Equipment Design

    Any biological treatment system is only as good as its process and equipment design. To ensure a successful installation the process and equipment must work together to meet the performance objectives.

    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

    • Clarifier (Integral or Independent)
    • Customer Support

    Specific applications may require pre or post treatment unit processes to meet desired treatment objectives. We work with our customers to provide recommendations or include required unit processes as part of the Nebula® MultiStage Biofilm System.

    The Nebula® MultiStage Biofilm System is suitable for installation in concrete (poured or precast), steel, fiberglass tanks / basins or designed as a complete package wastewater treatment system.

    The Nebula® Biofilm Media and Media Rack

    The design of the media support rack is equally important to the system performance as biofilm media. Support rack design must take into consideration dry and wet conditions of the media and the weight of the biomass.

    Our proprietary media is:

    • Chemically Resistant Textile
    • Highly Durable (Seat Belt Strong)
    • Hydrophilic
    • Greater Surface Area compared to other types of fixed submerged media

    The combination of the Nebula® MultiStage Biofilm System media and media rack design has demonstrated over 15 years of useful life without replacement.

     The Aquarius Aeration System

    Diffused aeration is integral to the success of the Nebula Multistage Biofilm System. It is designed to provide efficient and effective:

    • Transfer of Oxygen to the Biomass
    • Mixing Within the Treatment Stages
    • Scouring of the Media to Control Biofilm Thickness

    The aeration diffusers are positioned beneath the Biofilm media racks and anchored to the floor or attached to the media racks.

    Total Cost of Ownership Considerations

    When evaluating treatment solutions, we recognize that process design and equipment design are equally important to the performance and ultimately the cost of ownership. We strive to work closely with our customers to understand each unit process in the system, its function, and impact to the cost of ownership.
