Reduction of MS2 bacteriophage and rotavirus in biosand filters; Wang, H.; Li, M.; Brockman, K.; Nguyen, T.H., 2016
Evaluation of household drinking water filter distribution programs in Haiti; Rayner, J.; Murray, A.; Joseph, M.; Branz, A.; Lantagne, D., 2016
The biosand filter can function in a variety of climates and temperatures, but requires time to adapt to change. The filters should not be allowed to freeze, as this negatively affects the filter's ability to remove bacteria.
Vinegar-amended anaerobic biosand filter for the removal of arsenic and nitrate from groundwater; Snyder, K.V.; Webster, T.M.; Upadhyaya, G.; Hayes, K.F.; Raskin, L., 2016
Arsenic removal from drinking water by a household sand filter in Vietnam — Effect of filter usage practices on arsenic removal efficiency and microbiological water quality; Nitzsche, K.Sonja; Lan, V.Mai; Trang, P.Thi Kim; Viet, P.Hung; Berg, M.; Voegelin, A.; Planer-Friedrich, B.; Zahoransky, J.; üller, S.K.; Byrne, J.Martin; öder, C.; Behrens, S.; Kappler, A., 2015
Household sand filter in Northern Vietnam consistently reduces arsenic from groundwater by 95% irrespectively of usage practices and sand usage duration. The findings are probably transferable to other sand filters, such as the biosand filter, if similar groundwater compositions (e.g. iron:arsenic ratio >50, phosphate <2.5 mg/L), geological settings, well and sand filter properties exist.
Projects aiming to improve health cannot be just technology-driven, or the technology will under perform. Field situations are complex, and a holistic approach must be taken.
