Title

Development of a Mobile Water Disinfection Unit Powered by Renewable Energy

Abstract

Following such natural disasters as Hurricanes Katrina and Ike and the 2010 Haiti earthquake, it has become apparent that supplying a reliable source of clean drinking water is essential. Water supply and the associated transportation of potable water is a considerable burden on recovery efforts following a natural disaster. To reduce this burden and meet the water requirements of a community a low maintenance, low cost trailer mounted water disinfection system has been developed which has the capability to provide potable water from local surface water bodies until the infrastructure is repaired. To achieve disinfection of contaminated surface water the system uses a series of pre"filters and an ultraviolet (UV) disinfection unit. The system is powered using a hybrid photovoltaic array and wind turbine system. In an effort to increase the storage capability and decrease the maintenance required by the system, relatively high maintenance traditional batteries have been replaced with an ultracapacitor to store the energy generated by the renewable energy component. The prototype system was field tested throughout several months. Tests conducted on the system included monitoring of the energy generation and consumption of the system components and verification of the disinfection capability through sampling of various surface water bodies. The prototype performed as desired, however during testing the PV array provided sufficient energy and it was deemed that the wind turbine was redundant.
