Abstract
![CDATA[The lack of effective water disinfection in remote and developing areas contributes to the spread of waterborne diseases which claim millions of lives annually. Water sources vary in quality. The water distribution system in some areas is primarily biofilm-fouled water containers which cause contamination. To protect against the latter, advances in Point of Use (POU) technologies are urgently needed. One POU technology option is ultraviolet (UV) water disinfection which is effective for a wide range of pathogens, consumes no chemicals and leaves no odors, tastes or residues. Recent developments in semiconductor technology have produced UV-C (200-280nm) light-emitting diodes (LEDs), potentially suitable for POU water disinfection. In this paper, we examine the present state of LED technology and its synergies with PV. Experimental data from a prototype system will be presented which validates the concept. We also explore the cost benefit optimization of LED and power supplies. Parallels between PV pumping and lighting projects and benefits over SODIS will be discussed. It seems quite likely that in the near future, the PV-powered LED-based POU disinfection will be feasible and valuable for clean water supply in remote and regional communities.]]
