Ankur Omni-Processor

Partner

  • Descriptive Overview
    Ankur Scientific is a pending commercial licensee of the Gates Foundation's patented omni-processor technology. Ankur’s product incorporates the core omni-processor technology into a comprehensive fecal sludge treatment plant (FSTP) and municipal solid waste (MSW) solution, localized to the Indian context. The unit can accept fecal sludge, biosolids, and other biomass into the main processing system, and municipal solid waste into the added gasifier, part of Ankur’s existing products. Different input modes produce different outputs and remains environmentally safe - all discharge meet EU and local norms.
  • Key Features
    • Current design input is 200 KLD (wet sludge), with ability to scale size smaller or larger as needed by city
    • Greater than 97% reduction by volume
    • Proprietary municipal solid waste (MSW) gasifier addition enables co-treatment in integrated sludge and MSW mode
    • MBBR pre-treatment process maximizes industrial grade water extraction for reuse, and reduces footprint
    • Automatic and efficient: Processing time of sludge from its arrival to disposal is 6-10 hours
  • Use Case Details
    Standalone FSTP: Design can be a standalone FSTP taking direct input from vacuum trucks, processing liquid waste in membrane-based bioreactor (MBBR), and solids through the OP. Colocation with STP: Treat liquid effluent (beyond existing capacity of OP), and treat STP biosolids. Integration of sludge treatment with MSW.
  • Dimensions (meters)
    1600 m2 – 4000 m2 depending on variations and adaption
  • Other Waste Accepted
    Fecal sludge, biosolids, municipal solid waste, other biomass if needed. Proprietary MSW gasifier is included if co-treatment of sludge and MSW is desired.
  • Use Cases
    • Standalone FSTP
    • Collocation with STP
  • Interface Type
    Various
  • Frontend Description
    Fecal sludge is delivered to the plant and emptied into a sludge receiving tank where it is agitated before being transferred to a volute screw press for dewatering. Solid cake from the volute press travels to the dryer where it is dried to 90% solids before being transferred to the boiler for processing. Water vapor from the dryer enters a condenser where it is treated to distilled water quality, which can be used for a range of purposes.
  • Flush Water Source
    None
  • Users per Day (Expected)
    Current design input is 200 KLD (wet sludge), with ability to scale size smaller or larger as needed by city. Typical system serves approximately 300,000-500,000 people, but capacity is context- and system-specific.
  • Users per Day (Maximum)
    500000
  • Type of Waste Treated
    Solids Processing
  • Core Processing Technology
    Dry Combustion
  • Processing Overview
    Dried fecal sludge is sent to a boiler for combustion, generating a pathogen-free ash and high-pressure steam that is used to drive a turbine.
  • Processing Capacity
    Current design input is 200 KLD (wet sludge)
  • Processing Parameters
    The screw press dewaters the fecal sludge to approximately 20% total solids. Drying removes additional moisture to reach approximately 90% solids. Combustion in the boiler occurs at 900-950 degrees Celsius. High pressure steam from combustion is used to drive a turbine, and low-pressure steam is delivered back to the dryer to aid in the drying process. Sludge volume is reduced by 97%, and processing time from arrival to disposal is 6-10 hours.
  • Consumable Chemicals Needed
    May need auxiliary fuel for startup, lime and urea for emissions, acids/bases for pH control, and flocculant for dewatering
  • Type of Waste Treated
    Liquids Processing
  • Core Processing Technology
    Biological
  • Processing Overview
    Liquid filtrate from the volute press is treated by a moving bed biofilm reactor (MBBR), and treated water is stored onsite before discharge or use for agricultural purposes.
  • Processing Parameters
    MBBR pre-treatment process maximizes industrial grade water extraction for reuse, and reduces footprint.
  • Power Systems Overview
    High-pressure steam from the combustion boiler is routed to a turbine which generates surplus electricity that can be used onsite or sold.
  • Energy Balance
    No electricity or water input required. Energy recovered: - 170 kWe (stand-alone sludge mode) - 290 kWe (integrated sludge and MSW)
  • Capital Expense Estimate (USD)
    3000000
  • Capital Expense Estimate Notes
    Estimated capital expense of $2-3 million dependent on configuration
  • Operating Expense Estimate (USD)
    100000
  • Operating Expense Estimate Notes
    Annual operating cost approximately $100,000, dependent on application.
  • Expected Design Lifetime (Years)
    20
