Revolving Algal Biofilm (RAB) Systems

The RAB system uses vertically oriented conveyor belts that grow algae on their surface. As the algae grow it consumes nitrogen and phosphorus from the wastewater while it uses sunlight and carbon dioxide from the atmosphere to rapidly grow algae biomass.

This process is an effective method of carbon capture. The nutrient-rich algae produced through this process can also be harvested and sold as a slow-release algal fertilizer.

The RAB system is an effective pre-treatment solution for the food and beverage and other industries with high-strength biological wastewater, who must reduce their carbon footprint and achieve sustainability goals. The system can also be added to an existing wastewater lagoon as a secondary treatment, or as tertiary treatment when nitrogen and/or phosphorous treatment goals must be met.

The RAB system provides lower energy and operation costs and there are no chemical inputs.
