Membrane filtration reduces recontamination risk in chlorinated household water containers
conference contribution
posted on 2018-02-12, 15:11 authored by Regula Meierhofer, P. Rubli, K. Dreyer, H. Ouma, K. Wanyama, Maryna Peter-VarbanetsThe study was conducted in the catchment area of two Gravity Driven Membrane Filtration (GDM)
water kiosks in Uganda. It assessed if the cleaning and disinfection of jerrycans with chlorine can reduce
risks for regrowth and recontamination of treated water during storage in undisturbed containers, as
well as at the household level. In addition, the impact of water handling, household hygiene and safe
storage determinants on water quality was evaluated. Results indicate that the cleanliness of the water
storage container has a critical impact on water quality changes during storage. Safe drinking water at
the point of consumption after 24 hours of storage at the household level can be achieved with a
combination of ultrafiltration and subsequent chlorination.
