This article reviews progress in SANDEC's research project on solar water disinfection (SODIS). While previous research concentrated on batch processes where water was stored in bottles, SANDEC is now looking at continuous-flow systems. These consist of raw water and treated water tanks, solar collectors, exposure vessels, heat exchangers, and flow control devices. Field research on these systems at CINARA's research station in Puerto Mallarino in Cali, Colombia, revealed problems with the reactor design, flow and temperature control, and the use of adequate material. These problems needed to be resolved before there could be any practical application of continuous-flow systems. SANDEC is planning field tests of continuous-flow systems in Jordan, Lebanon and Thailand.
