Description
This powerpoint presentation begins by providing a brief overview of recharging Colorado River water and blending it withnative groundwater. Water quality and treatment goals are presented, along with processes needed to meet goals. Testing objectives included the following:evaluate if IX can reduce barium levels; minimize brine production fromregeneration;evaluate RO and NF relative saltrejection and operating pressures; and,evaluate VSEP membrane selection. Ion exchange issues to beresearched are presented, along with ion exchange testing parameters, and a summary of IX testingresults that include the following:SAC (Na+) was the only resin to reliablymeet barium goal of 0.02 mg/L;Barium broke through (0.02 mg/L) at ~500 bed volumes;Amberlite PWC14 performed the bestout of the four SAC (Na+) resins; and, salt requirements were more thanpreviously assumed (9.57 lb vs. 3.92 lbof salt per 1,000 gallons treated). Includes tables, figures.
