文摘

SODIS was effective with natural water containing wild bacteria (103 CFU/100 ml). But total inactivation was not achieved according to WHO standards (0 CFU/100 ml). Clostridium perfringens was highly resistant to SODIS, with only a 43% reduction. Water temperatures near the microbial optimum growth values might be antagonistic. Current electronic sensors require more research to be suitable for natural water.
