How it Works _______________________________________________________<br />
<strong>Hexavalent</strong> <strong>Chromium</strong> removal is a new application for the proven <strong>Photo</strong>-<strong>Cat</strong> technology. <strong>Photo</strong>-<strong>Cat</strong> readily<br />
REDUCES <strong>Cr</strong> 6 to the more desirable and significantly less toxic <strong>Cr</strong> 3 . During its reduction, all of the <strong>Cr</strong> 3+<br />
adsorbs onto the TiO 2 catalyst of the <strong>Photo</strong>-<strong>Cat</strong> and is REMOVED with the catalyst.<br />
The chromium laden TiO 2 is then processed and RECOVERS the chromium as a highly concentrated wet<br />
solid (<strong>Cr</strong>(OH) 3 ). The TiO 2 is sent back to the <strong>Photo</strong>-<strong>Cat</strong> (i.e. TiO 2 is completely closed loop). The entire<br />
process is automated and extremely energy efficient.<br />
<strong>Photo</strong>-<strong>Cat</strong> Enhanced Performance ______________________________________<br />
<strong>Cr</strong> 6 is eliminated by being reduced to <strong>Cr</strong> 3<br />
<strong>Cr</strong> 6 reduction is performed <strong>Photo</strong>-<strong>Cat</strong>alytically, and thus is ultra-low energy<br />
More cost effective than the current Ion Exchange process employed<br />
