- 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.
- Energy cost of the solutions implemented to solve these problems.
particulate extraction - water clarification - biosecurity
Aquarium water clarification and treatment
The microbubbles created in the system trap impurities as they rise and create a scum at the top of the column. This scum which is sucked up by the vacuum carries with it the particles which are trapped inside. These extracted particles are between 0.3 and 30 µm and are not trapped in conventional systems.

Particle extraction by the COLDEP system also makes it possible to trap bacteria, viruses and parasites in the water, thus ensuring the biosecurity of the installation. The clarification of the water also makes it possible to guarantee optimum UV efficiency and the absence of microalgae.
There is the possibility of extracting continuously or only a few hours a day.
dissolved gas management
Regulation of O concentration2 and N2
The bubbles associated with the vacuum created at the top of the column make it possible to achieve unmatched aeration and degassing efficiency. In addition, the COLDEP process makes it possible to prevent any risk of nitrogen supersaturation.

Testimonials
The COLDEP device was installed in a tropical basin of 200 m3, in which we had problems with water turbidity, despite conventional filtration, and the start of the growth of filamentous algae linked to an increase in the nitrate level. About a month after commissioning, the effects were very visible for these two problems. We have found excellent transparency in the water and the algae have completely disappeared.
