  • Descriptive Overview
    Tide Technocrats is a premier environmental and sustainability focused organization, based in Bengaluru, India. Tide Technocrats design for a fecal sludge treatment plant (FSTP) requires only a small footprint to collect and remove liquids from fecal sludge, before using a novel drying and pyrolysis technology to subject solids to extremely high temperatures. The omni-processor component uses pyrolysis technology from partner Biomass Controls. The FSTP produces pathogen-free “biochar,” a carbon-rich compound that can be safely used in horticulture to improve soil, and treated liquid effluent that can be used for gardening and landscaping. The technology is currently being piloted in three different urban locations in India to better understand how the process can be improved end-to-end, and established successfully in any urban environment. The process has been proven to accomplish complete pathogen elimination and is modular, scalable, with a quick setup time.
  • Use Case Details
    Provides an integrated FSTP solution.
  • Dimensions (meters)
    1,000-2,000 sq. m site footprint
  • Other Waste Accepted
    Biosolids, other biomass
  • Use Cases
    • Standalone FSTP
  • Interface Type
  • Frontend Description
    Design of plant can be easily established with municipalities, enabling vacuum trucks to empty faecal sludge and septage. After delivery at the plant, septage is moved to holding tank and then metered to a dewatering unit (2-5% solids input, 20-25% solids output).
  • Flush Water Source
  • Users per Day (Expected)
    30,000 (15 KLD) – 60,000 (30 KLD) people served. Assumed septage production rate of 2L per person per day.
