Aquadelle Technologies (A Dellepere Ent. Co.)

Aquadelle Technologies developed an advanced in-situ oxidation system deployed on purpose-built barges that inject ozone and oxygen directly into eutrophic water bodies, eliminating cyanobacteria blooms and restoring dissolved oxygen levels to ecologically functional thresholds.

The underlying Aquadelle model, peer-reviewed and published in the International Journal of Environmental Science and Technology (Tabla-Hernandez et al., 2024; doi: 10.1007/s13762-024-05577-w), demonstrates 100% elimination of Microcystis aeruginosa at 15 mg O₃/L, even under high organic load conditions.

By suppressing anoxic decomposition pathways, the technology directly curtails methane emissions — a greenhouse gas approximately 80 times more potent than CO₂ over a 20-year horizon — while simultaneously rebuilding the aquatic carbon-sink function of degraded lakes and reservoirs.

As the UNU-INWEH Global Water Bankruptcy report (2026) documents the irreversible loss of lakes, wetlands and aquifers globally, Aquadelle's barge-deployed intervention model represents a technically validated, cost-effective pathway to restore rather than abandon compromised water bodies.
