TECHNOLOGY
DEPO™ — Dual-stage ammonia Elimination Process via Oxidation
Under an electric field, specially catalytic anodes directly oxidize ammonia nitrogen (NH₃-N) to harmless nitrogen gas (N₂), while simultaneously producing hydroxyl radicals and active chlorine to inactivate 99.9% of pathogens. One DEPO system replaces four conventional systems: nitrification biofilter, protein skimmer, UV sterilizer, and ozone generator; dramatically reducing footprint and operating complexity.
High Efficiency
The ammonia removal rate exceeds 60%, with direct conversion into nitrogen gas. No secondary pollutants are generated.
Compact & Low Energy
Small footprint reactor that integrates easily into existing systems. Lower energy than traditional stripping.
Environmentally Friendly
Zero chemical additives required. Main byproducts are nitrogen gas with no toxic residues.
Adaptable & Smart
Tolerant to temperature, salinity, and pH variations. Fully automated with adjustable current density.
Real Customer Validation
Empirical data captured from active commercial aquaculture sites, proving the consistent efficacy of DEPO™ technological solutions.
Ammonia Removal >60%
Direct electrochemical conversion of ammonia nitrogen into harmless nitrogen gas.
Nitrite Removal >90%
Highly efficient reduction of nitrite levels to maintain optimal aquatic health.
Sterilization Rate 99.9%
Elimination of harmful pathogens without the need for chemical disinfectants.
Clearer Water Color
Strong oxidation potential removes chromaticity and organic coloring agents.
