Rialto Groundwater Wellhead Treatment System Project

Rialto, California

The new 2.8 MGD Water Treatment Plant is designed to remove perchlorate from groundwater through a biological degradation process. This featured technology uses suspended bacteria to consume salt anions within a fluidized bed reactor (FBR) treatment system. After the FBR’s, the process follows the stages of a traditional plant including aeration tanks, Trident filters, a dissolved air flotation (DAF) unit and additional process equipment. Construction also included the excavation and haul off of contaminated material, two underground concrete tanks, concrete slabs-on-grade, masonry structures, a pre-engineered metal treatment building and all the associated piping, electrical, and controls.
