Results of lab test NG RO (UV-lamp): Total microbial number
Conclusions: The samples were contaminated with microorganisms at the second stage of testing. After increasing the operating time of UV lamps, the concentration of microorganisms in the sample after UV lamp decreased by 3.5 times. The system is under revision.
