  • Method and apparatus for fertigation with wastewater
    Patent number: 10182524
    Abstract: Disclosed are a method and apparatus for blending wastewater with fresh water for fertigation of a crop. In one embodiment, the wastewater and the fresh water are blended at a predetermined flow ratio through a blending valve to obtain a blended stream. A logic based controller controls the blending valve to set a predetermined flow ratio according to the electricity conductivity (EC) of the blended water stream. The blending, measuring and adjusting steps form a feedback loop so as to maintain the blended stream at a target EC value.
    Type: Grant
