Document Description
New modular type ion exchange equipment will be added to the existing regenerable resin ion exchange (ISEP) equipment. The new equipment utilizes a National Safety Foundation (NSF) approved anion resin for the removal of Perchlorate, and the spent resin will require disposal once it has reached saturation point. The modular system will be set up in a lead-lag configuration, where source water will flow from the top of the lead vessel, discharged at the bottom, and continue to the top of the lag vessel. By removing the regeneration process of the resin, the brine solution generated will no longer contain any Perchlorate contamination, resulting in significant reduction of salt usage and brine disposal. The existing ISEP system would be modified to remove solely Nitrates. The proposed ion exchange equipment will be placed on a new concrete pad located across from the existing reservoir on the south side of the access road. The influent to the new ion exchange equipment will be connected at a point downstream of the existing air stripper booster station. A new booster pumps station with five (5) booster pumps and wetwell may be installed downstream of the new ion exchange equipment to increase the pressure for the water to make it through the remaining ISEP and UV treatment. The proposed booster station will be located adjacent to the single pass ion exchange equipment to the west. The booster pumps will be housed inside a new building similar in style to the existing booster building on-site. The wetwell will be constructed below grade under the new booster station.
