SEA PEN AERATION SOLUTIONS (SPA)WHAT IS THE PENTAIR SEA PEN AERATION SYSTEM?The Pentair Sea Pen Aeration System is a flexible and robust dissolved oxygen management platform. A unique pod-based approach allows the flow of compressed air to be controlled and balanced throughout each sea pen site. Each pod can be strategically placed throughout the pen at specific depths to compensate for conditions and optimize dissolution. The system can accommodate any number of sea pens at any one site with no limit on flowmeter panels or diffuser assemblies.

SEA PEN AERATION SYSTEM OVERVIEWThe Pentair sea pen plankton mitigation system is a fully balanced air flow system to evenly distribute compressed air among all the pens at one site. The main reason for an aeration system on a sea pen site is to promote greater water upwelling and movement across all the net pens on one site. Moving low density algae/plankton water from below helps dilute the algae/plankton density in the water inhabited by the fish within the pens to a reduced level. There are many different strains of algae/plankton that pose different threat levels to the well-being of the fish. As such, different air flows can be dialed into the flowmeters to control the delivery of air within each pen’s diffuser assemblies. This air control allows the site operator to mitigate different harmful plankton species, for each pen, based on the plankton’s unique motility. Because air is 1/5 oxygen a side benefit of up to 1.0 mg/L of dissolved oxygen increase has been documented, in conjunction with the mitigation of plankton blooms.

10.5”FLOWMETER ASSEMBLY PANELFlowmeter assemblies come in 4 variations; 7 flowmeter, 6 flowmeter, 5 flowmeter and 4 flowmeter versions. Each assembly features an oversized manifold with a pressure gauge and air control panel. Sturdy galvanized mounting legs ship with each unit to bolt to the pen walkways, for a stand-alone unit. Each panel includes a mort tube. A mort tube controls the flow of air for convenient mort removal.

The 5 flowmeter variation is for circular pens, and ships with pipe clamps to bolt to the large pipe handrails of the circular pens. For square pen installation, the flowmeter units are spread evenly among the net pens, usually one panel per pen. Each flowmeter panel services a single aeration platform to fully control air entering each site’s sea pen.
