Davis Street Landfill Reduces O&M with Sliding Tray Air Stripper

E-Z Tray Air Stripper in Davis Street LandfillWaste Management of Alameda County’s former Davis Street Landfill in San Leandro, California is the flagship of Waste Management’s Northern California operations. Beginning as a landfill in 1942, a portion of the site became an MSW transfer station in 1979 as the landfill closed. In 1990, a recycling facility was added to the transfer station site, serving 20 different Bay Area cities in achieving the required 75% diversion of MSW from landfills.

The closed 196-acre landfill site has a leachate collection system that maintains an inward gradient and produces about 60 GPM of leachate that goes to a treatment system prior to disposal. The system was originally designed using a stacking tray air stripper to remove methane from the leachate.  Suspended solids and biofilm that is deposited on the air stripper trays is routinely cleaned from the unit to maintain efficient operation. Unfortunately, the stacking tray stripper design proved to be a maintenance challenge.
