This powerpoint presentation begins by providing a brief overview of photocatalytic multi-barrier water purification, including Photocatalytic AOP+, ultraviolet (UV), and ceramic membranes. River water to potable pilot is presented, including: the pilot process; post Photo-Cat turbidity; test results; and, pilot results, May - August 2008. Relevant points include: unique reactor design provides active treatment and eliminates UV wipers; operation through storm events; not vulnerable to cold water operation; completely automated, one button to start; pilot run remotely; and, removes EDCs and PPCPs. Economic assessment includes: no membrane replacement cost; no membrane cleaning cost; no oversized membrane cost for cold, fouling, integrity, repair; uses existing pretreatment; smaller, less complicated building; eliminates permanganate; includes automation; and, low electrical demand. Includes tables.
