Abstract:
Closing the loop through nutrient recovery from different waste streams is now evolving as a necessary, sustainable development objective, driven by the urgent need to reduce consumption of vital natural resources (e.g. phosphate rock), reduce gas emissions and conserve energy. A better understanding of the chemistry, engineering and overall process integration is developing quickly and new treatment process trains are already on line globally. A new ‘paradigm’ in wastewater treatment is emerging for nutrient removal and recovery, with particular emphasis on phosphorus. Dramatically shrinking global reserves of clean, economically recoverable phosphate rock are necessitating this paradigm shift. Commercial marketing of recoverable nutrients as ‘green fertilizers’ , or recycling of those nutrients through biomass production into new outlets, such as biofuels, is now a reality .
An overview of recent research, process developments, technology transfer and global issues will be highlighted and discussed, including novel applications on the West Coast to re-build depressed salmon populations.
