The PR Aqua Swirl Separator is a proven technology that is effective at removing aquaculture waste solids (e.g. uneaten feed and fish feces) over a range of hydraulic loading rates. Where lower hydraulic loading rates are acceptable, PR Aqua Radial Flow Separators may also be considered for improved solids removal efficiency.
How It Works
Swirl separators concentrate solids based on the “Tea Cup Effect.” Culture tank effluent is introduced into the unit tangentially, creating rotational flow. As the swirling flow rises towards the outlet located near the top of the vessel, solids separate towards the center where velocities are lower, and eventually accumulate in the conical bottom. The clear water leaves the vessel by the overflow weir and the accumulated solids are periodically flushed from the bottom of the cone.
