Nitrate Pilot Testing


Nitrate Testing


The City of Ripon (City), in conjunction with Damon S. Williams Associates (DSWA), has conducted a pilot-scale investigation of an integrated nitrate and arsenic treatment system. This City of Ripon Integrated Nitrate and Arsenic Treatment Demonstration has been approved for California Proposition 50 funding under Chapter 6b.

The integrated pilot system implements chemical reduction of nitrate with SMI-III® followed by coagulation/filtration for arsenic removal. SMI-III® is a patented, iron-based granular media that has been commercially developed for the removal of nitrate, metals, and other compounds from water. It is foreseen that the greatest benefit of this technology is that it does not produce a costly brine stream as do the currently accepted nitrate removal technologies of ion exchange and reverse osmosis.


Project Update (4/2/10)

Pilot testing has been completed and testing results are attached.
