Abstract

One of the main problems in MICRO-IRRIGATION SYSTEMs is existence of SUSPENDED SOLIDS in irrigation water and consequently clogging of emitters. Thus, studying performance of water refinement unit is essential, especially when low quality water is used. Central control unit, which is responsible for filtration of water in MICRO-IRRIGATION SYSTEM, is the main factor for success or failure of the system. Most experts consider water filtration until as heart of MICRO-IRRIGATION SYSTEM, due to its importance. This study was conducted to investigate and evaluate the performance of sand and DISK FILTERs in central control until, in situation using low physical quality (High ORGANIC MATTER) water for irrigation. The amount of SUSPENDED SOLIDS in refined water was measured under different pressures. Also, variations of pore size diameters due to sand disturbtion after back washing were estimated in SAND FILTERs. The results of this study showed the possibility of clogging in some emitters in MICRO-IRRIGATION SYSTEM, in spite of presence of SAND FILTER. Also, the results showed that sand layers are disturbed in SAND FILTERs after back washing. The disruption of sand layer would affect pressure loss, the amount of SUSPENDED SOLIDS in passed water and the operational time. Finally, the results of this study indicated that the performance of DISK FILTERs were much better than SAND FILTERs in aspect of refined water physical quality and easy washing.
