Ballast water and fish farm treatment system

A ballast water and fish farm water treatment system for circulating effluent water from a source by filtering and resupplying the effluent water, the system comprising:

• a heat exchange system;
• a physical filtration unit connected to the heat exchange system via a first pipe and in fluid communication with the heat exchange system;
• a chemical filtration unit connected to the physical filtration unit via a second pipe and in fluid communication with the physical filtration unit;
• and
• a fine oxygen supplier in fluid communication with the heat exchange system and the physical filtration unit, wherein the fine oxygen supplier is connected to the first pipe to introduce oxygen bubbles into the effluent water when the effluent water moves from the heat exchange system to the physical filtration unit through the first pipe,
• wherein:
• the physical filtration unit comprising a plurality of phosphorus members and a plurality of diatomaceous fine cross-sectional membranes, said phosphorous members stacked in multiple layers with a diatomaceous fine cross-sectional membrane attached to one surface of each of said phosphorous members, the physical filtration unit configured to filter out, destroy, and extinguish parasites, germs and viruses in the effluent water and to dissolve the oxygen bubbles into the effluent water while the effluent water passes through fine gaps of the plurality of diatomaceous fine cross-sectional membranes;
• and
• the water treatment system is configured to resupply the effluent water, discharged from the chemical filtration unit, to the source, wherein the source includes a fish farm or a ship.
