SeaBreather 4.0 HS and 2.0 HS are aquatic remediation vessels (ARVs) capable of infusing (respectively) 4,000 and 2,000 water gallons per minute with life-giving oxygen. When loaded with embedded HABslayer AOP (advanced oxidation process) systems, they feature carefully controlled oxidant mixes. SeaBreather ARV and HABslayer AOP systems work seamlessly to form a powerful nanobubble delivery mechanism tested by NOAA for superior care of delicate aquatic ecosystems. They are designed to excel in tough freshwater and maritime conditions, performing swift mitigations of critical ocean-scale threats like eutrophication, harmful algal blooms, hypoxia, and acidification.
