Oxygen is added to ensure optimal oxygen conditions for fish growth
Foam fractionator and ozone injection: Improves water quality and increases the clarity by removing fine particles, complex organic substances and dissolved organic material
In addition, the system is set up with alarms for important parameters, so that the entire facility can be controlled remotely from the control room.
Technology and solutions OptiFarm consists of several different components, including OptiTrap, OptiFlow and OptiTank. OptiFarm, our concept for a complete RAS facility, is designed for ideal fish health and growth, and every single component in the system works and contributes to these factors.
