영문 초록

  The objectives of this study are to investigate the relationship between the silver ion concentrations released from the POU devices installed silver impregnated activated carbon filters and the antibacterial activities against HPC bacteria.
  Total of 68 POU devices were tested. The concentrations of the eluted silver ion from the silver impregnated activated carbon filter showed the range from 4 ㎍/ℓ to 386 ㎍/ℓ, and the HPC bacteria were found to diversely grow within the range 0-5,200 cfu/mL.
  The average silver concentrations released from UF units system and RO units system were 30 ㎍/ℓ and 73 ㎍/ℓ, respectively. The amounts of silver ions in the water passed through RO units system showed about 2.5 times higher than that of UF system units. And the number of colonies were reduced significantly as the elution levels of silver exceeded 100 ㎍/ℓ, however silver ions below the concentration of 100 ㎍/ℓ were not particularly effective for eradicating HPC bacteria from water.
  The pHs of permeated water through reverse osmosis membrane were relatively low compare to those of ultra filtration membrane.
