This is the
proposal of the farm, the idea is to clean the water of the culture
tanks in a clarifier or a sedimentation tank, then pass it thru the
NFT hydroponics beds and then do a
biofiltering and aeration
process to increase the Dissolved Oxygen level.
Examples can be found
at S&S Aquafarm & UVI,
Both of them
are applications of
the same principle.
