Oxygenated water and low CO2 level in water are essential for optimum water quality for fish farms. BIO-BLOK® is used as a trickling filter which gives you an energy efficient system.
Small Aeration and Degassing Unit
A small Aeration and Degassing unit is essential for outdoor landbased fish farms. The unit can be placed to oxygenate the intake water, the recirculted water and the discharge water.
The unit is easy to install, maintain and operate. The unit can also be used to remove ammonia.
Trickling Filter
For landbased RAS, a trickling filter is a good option for removing CO2 and oxygenate the recirculated water.
The trickling filter should be designed with a high hydraulic load to improve the efficiency.
The horizontal layer of BIO-BLOK® distributes the water while the vertical tubes give a good passage for the air to get in contact with the water.
