SOLAR WASTEWATER DISINFECTION SYSTEM AND METHOD

摘要

A solar wastewater disinfection system and method, the system including a solar collector configured to heat wastewater from a first temperature up to at least a second temperature, using solar energy; a pre-heater configured to heat the wastewater up to at least the first temperature, by transferring heat from the wastewater heated by the solar collector; a pump configured to circulate the wastewater between the pre-heater and the solar collector; and a controller configured to control the pump, such that the wastewater remains at or above the second temperature for a time period sufficient to pasteurize the wastewater.
