This powerpoint presentation presents a "silica scrub" procedure for improving arsenic adsorption media capacity. "Silica Scrubbing" is Severn Trent's term for reducing SiO2 interference. It is a patented process that uses an off-line procedure to dissolve SiO2 from media surface involving in situ media treatment, with the initial step prior to routine backwash. Process chemistry and procedure are outlined, along with bench scale testing, on site pilot testing, the Susanville, California, CDC Pilot, silica scrub results, and SiO2 Scrub Status. Includes figures.
