Worldwide, water security in arid regions is threatened by unsustainable use of groundwater and population growth. In order for villages, towns, and cities to be sustainable and prosperous, clean water is essential. This requires efficient treatment and reuse of wastewater.
ASU researchers led by Peter Lammers have developed an innovative system that employs a heat-tolerant strain of microalgae in a closed system for efficient wastewater treatment under hot, arid conditions at the Arizona Center for Algae Technology and Innovation (AzCATI). The bio-solids and algal biomass are then converted into energy, such as liquid fuel, through hydrothermal liquefaction or anaerobic digestion.
