The Reverse Osmosis water Purifier makes water, both chemically and microbiologically potable by reducing hardness, total dissolved solis (TDS) and heavy metals contaminats like Arsenic, Mercury and Lead. It also restores the orginal taste and essential minerals.
For the small scale production of hydrogen, water purifiers are installed to prevent formation of minerals on the surface of the electrodes and to remove organics and chlorine from utility water. First, the water passes through a 20 micrometre interference (mesh or screen filter) filter to remove sand and dust particles, then a charcoal filter using activated carbon to remove organics and chlorine and, finally, a de-ionizing filter to remove metallic ions.
