Filters are used to remove particles and contaminants in the water, as well as salmon lice and louse eggs when deworming is carried out in a wellboat. Filters must be used before UV treatment of water to remove particles that can create shadows in the UV chamber. Smaller particles in the water create good water quality and good fishing welfare. Clean water provides excellent conditions for growth.
Pressure filters ensure good filtration of the water, which ensures good water quality and prevents unwanted discharges. Automatic backwash filters ensure the separation of particles into the water stream using pressure and the Bernoulli principle. In a water treatment process, filters are used prior to UV treatment of water to remove particles that may reduce the effectiveness of the UV treatment.
