Water treatment to eliminate cyanobacteria and other toxins by unmanned surface vehicles (USVs)
TS-058408 — Freshwater resources around the world are under stress due to naturally occurring events and human impacts, causing an increase in cyanobacteria blooms. These cyanobacteria release harmful toxins, known as cyanotoxins. The proposed USV degrades the toxins on-site with UV light, reducing the accumulation of toxins, preventing groundwater contamination, and improving water quality.
Treatment of cyanobacteria and cyanotoxins is necessary before they reach a critical point, or they can contaminate other environments. For example, waste produced by water treatment facilities serves as fertilizer for agricultural land, and if not properly treated, toxic cyanobacteria can grow in…
