Performance evaluation of intelligent filters designed for water treatment in the irrigation systems

In line with the optimal management to water consumption, the usage of irrigation systems equipped with water cleanup systems increased the acceptance of these systems. In this research, a smart filter equipped with automatic self-cleaning technology was constructed. The experimental of this research in the form of a factorial test based on a completely randomized design with three factors working pressure, water quality and the diameter of filter openings with three repetitions in controlled laboratory conditions. The amount of water consumed will be higher for samples containing large amounts of impurities and filters with larger aperture diameters, and using filters with smaller aperture diameters and considering low operating pressure can reduce the amount of water consumed for washing. The results showed that the best quality of purified water (96.3%) and the lowest amount of water used for washing occurred (21.2 L) at a working pressure of 100 kPa, although this has increased the number of filter washing times. Setting the washing process at the beginning of the first point of pressure deviation causes a high amount of water to be purified in each cycle. Setting up the working pressure unit of the smart filter control unit within 100 kPa and using a net with an opening diameter of 0.1 mm reduces the amount of water used to wash (79%) and increases the quality of the treated water (90%), which will allow the use of waters containing large amounts of suspended soluble solid materials.
