We develop clean, sustainable technology.

Reliable • Effective • Economical

Leveraging nature to solve problems.

We reinvented the way pollutants are viewed through our innovative, patented technology that recovers nutrients from wastewater with algae and then recycles the nutrient-rich algae into slow-releasing algal-based fertilizer.

The Revolving Algal Biofilm (RAB™) System

Specification Sheet

Our patented, innovative RAB™ technology 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.

The nutrient-rich algae produced through this unique process is then harvested and purchased back by GWT to be pelletized. These algae pellets are then utilized for a variety of different applications and ensures your water’s useful byproducts do not go to waste!

Advantages of the RAB System

Lower Energy and Operational Costs

No Costly Carbon or Chemical Inputs

Simply Scrape Harvested Algae

Sellable Algae Offsets Operational Costs

Economical solutions for your industry.

Our RAB™ system can be used for a wide variety of municipal and industrial applications as a sustainable, environmentally-friendly water treatment solution that is reliable, effective, and more affordable.

We don’t just think green, we grow it.
