Solar Water Disinfection: Field Test Results and Implementation Concepts
Abstract
Between 2006 and 2010, a simple solar water disinfection system called SoWaDis with almost no need for maintenance has been developed at the Institute for Solar Technology SPF in Rapperswil (Switzerland). Since 2009, several systems have been installed at various locations in Bangladesh, Mozambique and Tanzania. The device has been developed for remote areas with a maximum output capacity of the smallest unit in the range of 500 liters per day. The whole development covers three main working areas: A detailed study on thermal inactivation of pathogen microorganisms, the technical development of the device and field testing including the investigation of suitable implementation concepts that lead to a sustainable application.
