    Study Shows PHA Effect on Nitrate in Recirculating Aquaculture Systems

    With the advancement of solid organic carbon dosing, colloquially referred to as BioPellets, one of the fundamental areas lacking has been research. We have yet to find the best method to utilize them.

    Back in 2006 a company by the name of Aquaculture Systems Technologies received a Phase 1 USDA Small Business Innovative Research award to investigate the use of one of the most popular BioPellet materials–PHA or polyhydroxyalkanoates.

    Specifically PHA from Iowa based Meril / Metabolix was used in a self cleaning reactor design dubbed the PolyGeyser. The idea here was to develop a cheap and easy way to provide nitrate management in aquaculture systems. The nutrient levels AST tested these systems on are elevated from our own, but their is certainly some crossover and learning that can be done.

      Aqua-Medic has been selling carbon-source, biodegradable polymers for this purpose for over 15 years (as Deniballs to be used in their NR 1000 denitrifying filter). The only difference is Aqua-Medic uses a recirculating pump and slow flow throughput to keep the anaerobic bacteria in an appropriate environment.
