Tower aerator

For organic contaminant removal from surface water packed-tower aeration, granular activated carbon (GAC), powdered activated carbon (PAC), diffused aeration, advanced oxidation processes, and reverse osmosis (RO). [Pg.9]

Packed tower aeration (PTA), also referred to as packed column aeration (PCA), is a waterfall aeration process that trickles water down through and air flow up through plastic... [Pg.21]

PTA systems are designed so that water cascades, which imparts the necessary turbulence and air-to-water interface. Tray-type towers impart the turbulence to water by using several layers of slats to mix water with air. Innovations in PTA are reflected in the newest additions to the tower aeration system. Emerging aeration techniques include the catenary grid and Higee systems, which are discussed below. [Pg.30]

A full-scale packed tower aeration column plant using groundwater at an air-to-water ratio of 25 1 achieved 97-99% reductions from initial TCE influent concentrations ranging from 1500 to 2000 pg/L. [Pg.37]

A pilot packed tower aerator with 9 C influent, achieved up to 99.27% removal of vinyl chloride. [Pg.37]

A spray tower aeration unit removed vinyl chloride from groundwater with VOC concentrations of 100-200 pg/L. [Pg.37]
