Water purification in fish farms

Securing the best possible water quality is essential in every fish farm, whether based on conventional flow-through or intensive recirculation. The first step in water purification is to remove the highest possible amount of sludge and faeces before any other following water purification in drum filters/micro screens, and not least before any water purification with UV-light or ozone.

FREA Solutions has developed a sludge cone that is easy to install and operate in any fish farm. The efficiency of the sludge cone has had the effect that man farmers have left out investments in drum filters/micro screens that are costly both as investment and in operation/maintenance.
