RO systems should be maintained properly to be effective, says study
The authors of the study argue that using only RO devices as a stand-alone solution to urban drinking water safety may not be effective. | Photo Credit: File photo Installing reverse osmosis (RO) systems alone at home is not a guarantee for safe drinking water, a recent study has found. While the technology has been proven capable of removing microbes under ideal operating conditions, a field level study in Chennai showed that microbial contamination was detected in samples from RO units, highlighting the lack of regular maintenance and filter replacement as key issues. The results of the study ‘Evaluating Household Reverse Osmosis Systems for Microbial Safety: A Case Study from Chennai, India’ were recently published in the peer-reviewed Journal of Exposure Science & Environmental Epidemiology. The researchers Suzan Kagan et al, aimed at assessing the microbial safety of drinking water before and after household RO treatment to understand how education and awareness influence household water and maintenance practices. The survey conducted in Chennai covered 262 water samples from 216 households, looking at both treated and …
