Rainforest Algae for Aquaculture
Advanced Photobioreactor Systems for RAS, Wastewater Treatment, and Sustainable Fish Farming
Transforming Aquaculture Infrastructure
Rainforest Algae develops advanced aquaculture water treatment systems designed for recirculating aquaculture systems (RAS), land based fish farms, and hatchery facilities. Our technology improves water quality, stabilizes dissolved oxygen levels, and supports healthier fish production while reducing nutrient accumulation and operating costs.
We engineer biological infrastructure that improves water quality, reduces energy demand, and converts nitrogen waste into productive algal biomass.
Bench-scale yield breakthroughs were achieved in 2022. Our focus now is commercial-scale deployment and integration into operating aquaculture facilities.
The Challenge Facing Modern Aquaculture
Aquaculture is scaling rapidly, but water quality management remains the limiting factor.
Every recirculating aquaculture system must continuously manage ammonia, nitrate accumulation, carbon dioxide buildup, dissolved oxygen demand, and sludge generation. These factors directly affect fish mortality, stocking density, regulatory compliance, and operating cost.
Conventional biofilters and aeration systems are energy intensive and increasingly inefficient at higher production densities. Effluent management is not optional. It is a permanent operational cost.
At the same time, producers face volatile feed markets, rising energy prices, and increasing environmental reporting requirements.
Our technology is engineered to Integrate with Existing Aquaculture Infrastructure.
A New Model for Aquaculture Water Treatment
Rainforest integrates advanced enclosed photobioreactors (PBRs), a high-performance biofilter engineered for accelerated reaction kinetics, and extraordinary gas–liquid mass transfer technology into a unified biological treatment platform.
Rather than treating aquaculture effluent as a liability, the system converts dissolved nutrients and carbon into productive algal biomass while enhancing core water treatment performance.
The result is infrastructure optimization — delivering regulatory compliance, reduced emissions, reduced freshwater use, improved profitability, and measurable performance gains without replacing existing aquaculture systems.

System Impact at a Glance
Rainforest’s biological treatment platform improves water quality, oxygen transfer, and nutrient processing within aquaculture systems. The figures below illustrate modeled performance from a representative system configuration.
Example Output from a 225 m³ System:
of CO₂ removed per year
of O₂ released annually
of algal biomass generated annually through nutrient recovery
of clean, recirculated water
Figures represent modeled projections under standard operating conditions. Actual performance will vary depending on biomass composition, system configuration, and site-specific environmental inputs.
Economic Performance for Operators
Operators can achieve reduced fish mortality, lower energy use per cubic meter treated, reduced sludge handling costs, lower freshwater exchange requirements, and improved stocking density. In addition, algae cultivated on site can serve as feed supplementation or a separate revenue stream, depending on facility design.
Return on investment (ROI) is primarily driven by operating expense reduction and production stability.
