Freshwater-recirculating aquaculture system

Abstract

Disclosed is a freshwater-recirculating system of the type including: a pre-treatment module for pre-treating water from an aquaculture tank; an oxidation module for eliminating pollutants; and a line for recirculating the treated freshwater to the cultivation tank, before passing same through a post-treatment module. The system also includes a module for the electrochemical generation of oxidants, which is disposed in an auxiliary line, outside the main line for recirculating the treated freshwater, and which is supplied by a line for recirculating water coming from the outlet of the post-treatment module, the module for the electrochemical generation of oxidants being uncoupled from the oxidation module but in fluid communication with same by means of a line supplying electrogenerated oxidants.
