Water from rivers and wells is salinized in Mekong Delta has a salt content up to 6.000ppm (6g/1 liter of water or 0.6%), which affects plants badly, causes low productivity and wilting. Salt crystals and acid enclose roots and soil preventing nutrition absortption of roots and leaves. EZ water destroys salt molecules and acid, which make them unable to become hard crystal residues. Principle of operation of EZ energy machine: salt molecules and acid will be destroyed when water goes through reaction section of EZ energy machine. EZ energy water can purify contaminated soil by salt, acid and heavy metals like Zn, Cu, cadmium Arsenic deep in the ground. EZ energy water can do this naturally without using shovels.
