:: Chromium Removal & Recovery Mining Water


Purifics is driving innovation at a US EPA Superfund Site by recovering chromium from water, effectively mining water for mineral reuse with its FDR (Filter, Destroy, Recover) process at the rate of 400 gpm.

Using Photo-Cat AOP+ and DeWRS (DeWatering Recovery System) technology, Hexavalent Chromium, a carcinogenic contaminant widely known from the Hollywood film Erin Brockovich, is being reduced from 340-350ppb to below the detection limit of 15ppb - well below the design discharge requirement of 50ppb.

Purifics™ continuous filtration process displaces conventional ion exchange technology and has demonstrated an OpEx reduction of 66% with higher levels of purification and zero liquid discharge.

This technology can also be applied to the recovery of phosphorous, a limited resource, for municipal and agricultural waste water.
