User acceptance: the key to evaluating SODIS and other methods for household water treatment and safe storage
Get PDFHousehold water treatment has been identified as one effective strategy to interrupt transmission routes
of diarrhoea causing
pathogens, and thus to mitigate the global burden of waterborne
diseases. And yet,
the commitment of governments and international organizations to integrate household water treatment
and safe storage (HWTS) into their water supply, sanitation, and hygiene promotion programmes
remains limited. More efforts are required to scale up the initial successes in the promotion of HWTS
methods, and to achieve sustainable application at user level. This article illustrates the experience with
the promotion of one particular HWTS approach solar
water disinfection (SODIS) as
an input to the
debate on effectiveness, user acceptance, and integrated planning in the context of HWTS approaches

SORAS - a simple arsenic removal process
No full textThe serious threat to the health of millions of people through consumption of arsenic-rich groundwater in Bangladesh calls for immediate action on various levels. One of these actions is be the development of a low-cost and simple arsenic removal method available to every household. The development of alternative water sources and/or the installation of larger arsenic removal units will take more time due to logistic and financial constraints. Currently existing small-scale arsenic removal procedures require chemicals
that are either not easily available and/or affect water taste and odour.
Solar oxidation and removal of arsenic (SORAS) is a simple method that uses irradiation of water with sunlight in PET- or other UV-A transparent bottles to reduce arsenic levels from drinking water. The SORAS method is based on photochemical oxidation of As(III) followed by precipitation or filtration
of As(V) adsorbed on Fe(III)oxides as shown in Fig. 1. Groundwater in Bangladesh naturally contains Fe(II) and Fe(III) and therefore, SORAS could reduce arsenic contents and would be available to everyone at virtually no cost. It could be a water treatment method used at household level to treat
small quantities of drinking water
