Objective:

The objectives are 1) life cycle assessment (LCA) and technological economic analysis (TEA) of reactive filtration water treatment systems; 2) advancing a novel biochar water treatment process for phosphorus adsorption onto biochar for removal and recovery from wastewater effluents; and 3) development of an advanced, high-flow particle separations technology based on biological and natural processes for removal of nutrients from treated waters.

Conclusions:

Continued publication activities related to two manuscripts in preparation for submission based on the outcomes of this project.
Post-project continued biochar water treatment process modification, characterization, and enrichment process with protocol development targeting phosphorus adsorption to develop a mechanistic understanding of biochar modification process impacts at a bench scale and in pilot processes.
Post-project continuing ISO compliant LCA analysis on related process innovations contributing to nutrient reduction and mitigation of harmful algae blooms exploring climate, environmental health, water quality and social impacts.
Post-project continued exploration of carbon negative advanced water treatment using biochar and rock dust.
Post-project continued development of pilot scale separations technologies using nano/micro bubble fractionation and physical simplification of complex wastes streams.
Post-project continued greenhouse trials with recovered nutrient-loaded biochar materials.
