| 1 | This standard covers systems employing Point of Use (PoU) ultraviolet technology for disinfection of water systems up to a flow rate of 2 litres per minute (LPM). The system is expected to give water free from water borne pathogens, which is safe and suitable for human consumption. | |
| 2 | This revision is undertaken to update the standard in line with the latest technological developments. In this revision, the following major changes have been incorporated: a) LED based technology has been considered and suitably incorporated in the standard. b) Challenge organism Sarcina lutea (Micrococcus luteus) for evaluating microbiological reduction has been replaced with MS2 and Qbeta coliphages considering that MS2 coliphage is one of the more resistant microorganisms, suitable to be used for UV based systems operating at 254nm and for wavelengths other than 254nm Qbeta coliphage is the bacteriophage of choice which gives a linear dose response reaction. c) The figures have been replaced with schematic representation of different systems. | |
