Full Description
The capacity of biological filtration to control taste and odor (TC and all others at 20 C.Geosmin and MIB were initially spiked in at a target concentration of 100 ng/L. Afterfour months of operation, the MIB removal in the three pre-acclimated BAS filtersaveraged 46 % removal at the lab temperature, while nearly no removal (5 %) wasfound at 5 C with the pre-acclimated BAS. After four months the un-acclimated sand in5 averaged 10 % removal. The MIB removal in the BAC columns was about 65%,higher than that with BAS at lab temperature. After four months of operation theconcentration in all filters was increased to 200 ng/L for two weeks and the removalpercent remained the same. Includes 2 references, tables, figures.Cart
