Report 8/18/2014 9/16/2014 11/3/2014 Approved
Description : 3-month pilot test involving reverse osmosis (RO) treatment of filtered water to reduce/remove nitrate contamination and disinfection byproduct precursors as well as improve finished water taste and odor. NOTES re: 1) nitrate concentrations during test, 2) RO feed water & permeate anal...
Report 7/16/2015 10/8/2015 11/20/2015 Approved
Description : RO Pilot Study: new RO system, chemical feeds (CO2, sodium bisulfite, antiscalant, NaOH, phosphate; relocate F), corrosion testing, upgrade river intake pumps, antidegradation analysis. NOTES: 1) base design on 20-hr operating period, 2) NO3 units, 3) contact NPDES section re permit m...
Report 2/23/2016 5/17/2016 7/12/2016 Approved
Description : antidegradation alternatives analysis
Chemical addition, Treatment 4/28/2017 9/26/2017 10/17/2017 Permitted 2018-0008W
Description : 1 reverse osmosis (RO) membrane treatment system (3 skids, total maximum permeate capacity 2.5 MGD) primarily to reduce/remove NO3 contamination and DBP precursors from a portion of the WTP filter effluent; installation of chemical metering equipment for the addition of sodium bisulfite so...
CT Evaluations 3/10/2021 4/22/2021 10/23/2023 Dropped
Description : Added RO. Skipp noted to recheck CT (pH change?) due this addition. Nothing really changed in terms CT due to RO addition. Hence Dropped. Talked to Bob C.
