    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.

    Abstract: A drip irrigation emitter includes first and second members and a deformable membrane. The membrane is located between the members, and pins that are located on the first member are received within holes formed in the second member. End portions of the pins that project out of the holes are deformed and by that press the first and second members together and compress the membrane.
