      abstract     = {The increasing discharge of nutrient-rich wastewater into
                      natural water bodies poses a severe environmental challenge,
                      demanding innovative and cost-effective solutions for
                      efficient nutrient removal and recovery. This study first
                      aims to validate the hypothesis that the Algal Turf Scrubber
                      (ATS) system, an advanced algal biofilm reactor, can
                      effectively remove and recover nutrients from wastewater
                      under diverse environmental conditions. Rigorous evaluations
                      were conducted, including laboratory-scale tests varying
                      total inorganic carbon, nitrogen-to-phosphorous (N:P) ratio,
                      and light intensity (Chapter 3), and continuous operation of
                      technical-scale ATS systems in a greenhouse, analyzing their
                      nutrient removal and recovery under different temperature
                      and light conditions (Chapter 4). Mathematical modeling
                      elucidated the system's responses. The findings reveal that
                      the ATS system exhibits rapid and effective removal of
                      phosphorus and nitrogen from wastewaters while
                      simultaneously generating nutrient-rich biomass.
                      Furthermore, the ATS system demonstrates robust performance
                      across a wide range of temperature and light intensity
                      conditions. Notably, the ATS system offers a cost advantage,
                      with the biomass production cost being only $18\%$ of that
                      associated with conventional tubular photobioreactors.
                      Overall, the results demonstrate the cost-effectiveness and
                      versatility of ATS system as a technology for efficient
                      nutrient removal and recovery from wastewaters, making it
                      suitable for various regions.To test the hypothesis that the
                      ATS system provides a viable pathway for recovering
                      nutrients from wastewater and ultimately promote plant
                      growth, we used biomass harvested from the ATS system as an
                      organic phosphorus fertilizer in subsequent greenhouse pot
                      experiments to evaluate its effectiveness on plant
                      performance and phosphorus uptake by wheat (Chapter 5). The
                      results indicate that phosphorus derived from algal biofilms
                      is as accessible in similar rate as from mineral fertilizer,
                      highlighting the potential of algal biofilms as organic
                      nutrient sources for wheat cultivation.In summary, ATS
                      systems emerge as potent tools for achieving efficient
                      nutrient removal and recovery in various environments. In
                      addition, the harvested biomass holds promise as a robust
                      organic fertilizer, thus reinforcing advocacy for
                      sustainable agricultural practices and marking a significant
                      advance in environmentally friendly wastewater management
                      practices.},
