Description
Summary:Abstract –A drinking water disinfection and filtration system was designed using inexpensive and accessible materials. The prototype was constructed from two barrels and a pump that circulated water through a gravity sand filter before injection with locally-generated chlorine produced through saline electrolysis. System turbidity reduction and disinfection effectiveness was determined using surface water from ---. Ninety gallons of water showed a 70% reduction in turbidity and no coliform bacteria were detected after ninety minutes of operation. The system was built for less than $900 (2017) and is safe, simple, and reliable.
