Conventional wastewater treatment methods often consume significant energy and rely on chemical inputs, leading to high operational costs and environmental concerns. Traditional systems may also struggle to efficiently recover valuable resources like nitrogen and phosphorus from wastewater streams.
Gross-Wen Technologies offers the Revolving Algal Biofilm (RAB™) system, a sustainable wastewater treatment solution that recovers nitrogen and phosphorus while producing algae biomass. The RAB™ system utilizes an algae-based approach to remove nutrients from wastewater, reducing the need for energy-intensive processes and chemical additives. This technology provides a cost-effective and environmentally friendly alternative for municipal and industrial wastewater treatment, offering resource recovery and reduced carbon footprint. The algae byproduct can be further processed into valuable materials, enhancing the economic and environmental benefits of the system.
The primary customers are municipalities and industrial facilities, including food and beverage processors and agricultural operations, seeking sustainable and cost-effective wastewater treatment solutions.
