device for oxygenating an aquaculture tank

摘要

A device for oxygenating an aquaculture tank comprises a water recirculation line and a hydrogen peroxide dosing unit connected thereto. The recirculation conduit comprises a water inlet for withdrawing water from the tank, a recirculation pump downstream of the water inlet and a distribution conduit having a plurality of liquid outlets disposed downstream of the recirculation pump and submersible in the tank. at a fixed height of 5 to 50 cm above the bottom of the tank. The hydrogen peroxide dosing unit is connected to the recirculation line upstream of the distribution line. An aquaculture tank can be oxygenated by recirculating tank water with the device by adding hydrogen peroxide from the hydrogen peroxide dosing unit.
