I am looking to build a small-scale hydroponic farm; lettuce/tomatoes/etc, and am now looking into a filtration system for my re-circulating reservoir. I have previously run into pathogen issues within my system in Florida, so for this up-scaled version, i would like to add some type of filtration to the nutrient solution, to kill off any bacteria/pathogen buildup.
After some research, i have found a few solutions: UV Filtration Slow filtration Adding Ozone gas Heat pasteurization The list goes on...
I am curious, for a small scale ~5000 plant sites, coming from a ~500 gallon reservoir, what is the most efficient (time & cost) process.
I would assume slow filtration would be easiest to setup, and passive, however requires a decent amount of Maintenace.
Ozone & Uv seems fairly simple, plug & play, while heat pasteurization seems like a larger process to setup.
Any advice would be much appreciated.
