SIGNAL HILL NANOFILTRATION WELL NO. 9 ADVANCED WELL HEAD TREATMENT PROJECT

CITY OF SIGNAL HILL

The Design-Build team was responsible to design, procure, construct, obtain permits, and provide start-up and commissioning of the City of Signal Hill’s treatment facility to treat between 1,200 to 1,400 gallons per minute (gpm) of groundwater from Well #9. Recovery rate shall also be designed to be easily expandable to 1,800 gpm in the future. The water from the existing Well #9 contains high levels of color (<50 color units) but low salinity (>400 mg/LTDS) and is treated using nanofiltration membrane process. The goal of this project was to produce a product water with color below 5.0 color units without significant reduction of the concentration of dissolved ions. Final product water must also meet all State and Federal Drinking Water Standards.

This design-build project included equipping the existing Well #9 with pumps, designing and installing a nanofiltration treatment facility consisting of cartridge filters and two nanofiltration trains capable of operating at 98% recovery; a pump, motor, valves and piping; a clean-in-place system; chemical feed systems for pre-treatment and post-treatment; concentrate discharge tank; product water storage tank; yard piping and connections for potable water, and sewer and storm drain facilities. Work also consisted of site improvements including paving, concrete, lighting, gravel, and drainage facilities; metal canopy over the chemical and process area; metal building for electrical equipment, control equipment, restroom, operator training room, and HVAC system; emergency generator; and electrical, and instrumentation and control system.
