This powerpoint presentation begins by providing a brief overview of the city of Camarillo, California, and a pilot project to identify a treatment
process that will make the aquifer usable, thus creating a reliable, local, cost-effective water
supply for the city of Camarillo. The pilot approach included evaluating pretreatment processes, nanofiltration (NF)/ reverse osmosis (RO) optimization and confirmation
testing, and taking advantage of the difference in
oxidation rates between iron and
manganese when air is used for
oxidation. Presentation conclusions indicate the following: aeration + media filtration effectively
removed iron with 6 min contact time; complete oxidation achievable with < 1 min
contact time at pH 8, but pH adjustment not
practical due to high hardness in source
water; aeration + microfiltration far less effective; no Mn oxidation during initial testing
periods, however, subsequent testing
showed partial oxidation accelerated by
MnO<sub>2</sub> in media; ultimately, aeration + filtration pretreatment
was not recommended for full scale facility. Includes table, figures.
