RO Permeate Stabilization for Hyperion Advanced Water Purification Facility

The Hyperion Advanced Water Purification Facility is a ìproof of conceptî treatment project that will provide highly treated water for multiple non-potable uses at the Los Angeles International Airport (LAX) and the Hyperion Water Reclamation Plant (HWRP). These uses may include make-up water for cooling towers, toilet flushing, boiler feed makeup and landscape irrigation. The process will also provide an opportunity for the staff at Los Angeles Sanitation and Environment (LASAN) to gain hands-on experience with advanced water purification technologies, including membrane bioreactors, reverse osmosis, and UV advanced oxidation, and post-treatment stabilization to prepare operators for future, large-scale advanced treatment system operation (Hyperion 2035 Program). This paper details the multiple purposes of the project, its unique design features, and challenges during design and early in construction. The site area constraints, soil conditions, and existing 2 facilities posed several challenges to the design-build team. The process design challenges included a highly variable influent quality and a need for a pure, non-corrosive product water.
