Low Tech–Low Cost Micro Biogas Systems

Uniquely Designed for

FISH FARMS & HATCHERIES

AQUA-ENERGY is a provider of an advanced anaerobic digester technology that is simple in design yet highly efficient and cost effective. Our digester is uniquely engineered to convert manure wastes from fish recirculating aquaculture systems (RAS) and other wet organic wastes (food and livestock) into methane rich biogas and organic fertilizer. The biogas can be used to:

  • run an engine for power generation (with waste heat and CO2 recovery)
  • boilers for process hot water
  • unit heaters for space heating
  • after digestion the remaining nutrients in the digestate may be used as organic fertilizer for crops

BENEFITS OF TECHNOLOGY

  • Solves environmental problem of managing fish manure solids
  • Reduces odors and methane gas emissions
  • Lowers carbon footprint
  • Generates clean renewable energy
  • Helps make fish farms and hatcheries more self-sufficient and sustainable
  • Lowers utility costs

AQUA-ENERGY is joint venture between Aquacare Environment and Ecoponex Systems International. We have teamed up with Sistema BioBolsa of Mexico to offer this proven digester technology for markets in the US and Canada. Sistema manufacturers the basic components of the digester including the bioreactor. With funding from a number of NGO’s and foundations (Shell Foundation, Clinton Foundation, Tata Trust, eFactor, etc.) Sistema developed the low cost-low tech system for application in developing regions around the world including Mexico, South America, India and Africa.

IMPACTS OF PROVEN TECHNOLOGY

  • 3,900+ digesters installed world-wide
  • Pilot test units at Colorado State University’s Energy Institute, Santa Clara University and in Mexico City
  • Projects implemented in collaboration with various strategic partners
  • 19-million Nm3/yr of biogas produced
  • 6.5 million tons/yr of waste treated
  • over one thousand jobs created
  • many small farmers and villages have clean energy

SYSTEM DESIGNED FOR SMALL-SCALE COMMERCIAL AND INDUSTRIAL USE

Engineers with Aqua-Energy have enhanced the functionality and performance of the basic Sistema digester. The result of these improvements:
  • Potential increase in biogas yield from1.0X–2.0X over conventional systems
  • Reduced process time (HRT) from 45 to 21 days or less
  • 80% to 90% conversion of volatile solids

ENGINEERED IMPROVEMENTS

  • Process controls to automate system
  • Bio-catalyst to enhance carbon conversion
  • Mechanical mixing by gas bubble sparging
  • Thermal insulation with installation in building enclosures or greenhouses to help maintain 25oC operating temperature
