Algae-based Treatment of Dairy Wastewater & Generation of Renewable Energy
Algae-Based Wastewater Treatment for Dairies Results in Multiple Benefits that Improve the Bottom Line
QBI constructed a fully integrated dairy wastewater treatment system using microalgae for improved energy efficiency and water reclamation at the Van Ommering Dairy in San Diego County. QBI worked with CADMUS Inc., to conduct an independent assessment of the demonstration units performance, energy savings, water quality and created detail Excel based tools to assist other dairies in designing an algae based treatment suitable for their operations.
This project designed, built and demonstrated a low-cost algae-based solution to address the wastewater challenges facing one of California's largest agricultural sector. Project results showed that the system significantly improved effluent water quality with significantly reduced operational costs compared to traditional aeration-based systems. In addition, the algae biomass was shown to be a slow release fertilizer, enhancing the growth of crops on site. If deployed on California's dairies, such a system could help reduce state-wide water and energy use.
