We are heading up a large pilot study in collaboration with Jacobs Engineering and a Minnesota water utility. The pilot plant will include lime softening, ozone and ozone/AOP, GAC-biofiltration, chloramination, and pipe loops. The goals of the project include: 1) assess the potential benefits of preoxidation at limiting disinfection byproducts including NDMA and at removing trace organic contaminants (so-called CECs), 2) assess the effects of preoxidation on biofilter performance including particle removal and headloss, 3) assess the effects of treatment changes on distributed water quality including corrosion of premise plumbing (i.e., Pb and Cu), and 4) provide results that can be used for designing an upgraded full-scale facility.
Undergraduate researchers are needed immediately, in the summer, and in the fall semester. If interested, please send a resume and unofficial transcript to Prof. Ray Hozalski ([email protected])
