Ex-Situ Packed Bed Bioreactor (PBBR)
The reactor is made of fiberglass shells. Each reactor has 9 aeration cells with beads. The beads are designed in such a manner that the specific nitrifying bacterial consortium gets immobilized on the surface of the beads. The Packed Bed Bioreactor contains 60 kgs of beads with a surface area of about 28.26 m² and specific surface area of about 205 m² / m³ to facilitate removal of harmful nitrogenous compounds.A reservoir tank and a collecting tank are integrated for facilitating flow of water from the former to the latter.
The Ex-Situ Packed Bed Bioreactor (PBBR) serves the purpose of reuse and recycling of spent water for larval production and for the treatment of fresh seawater taken into the hatcheries. This is a key component for the establishment of Recirculating Aquaculture Systems (RAS)
- Establishment of Recirculating Aquaculture Systems (RAS) for maturation and brood stock maintenance.
- Establishment of Recirculating Aquaculture Systems (RAS) for larval production.
- Nitrification of the incoming water.
- Spent water treatment and reuse.
Nitrifying bioreactors can be used for establishment of Recirculating Aquaculture Systems (RAS) in any marine water / brackish water / fresh water seed production systems including those of Prawn, Shrimp, finfishes, mollusks etc., and also in ornamental fish culture systems.
