The COLDEP process resolves the main technical limitations encountered by water recirculation systems in aquariums:
- Decrease in the oxygenation level of the water.
- CO accumulation2 dissolved in water.
- Risk of nitrogen supersaturation.
- Abundance of small particles <30 µm which are not captured by conventional filters, which clog drum filters and reduce the effectiveness of UV treatments.
- Presence of bacteria and viruses in the water.
- Presence of microalgae.
