Abstarct: Today, the use of filtration systems and measuring their performance in connection with the efficiency and productivity of irrigation systems under pressure is an important part of the process of farm management and the improvement of the level and amount of produced products. So far, neglecting this issue has created major challenges for farmers and farmers at the macro level and farms studied in this research. baxsed on this, the current research seeks to evaluate the hydraulic performance of filtration stations in operational conditions, identify the problems and obstacles ahead and provide suitable solutions for the maximum efficiency of pressurized irrigation systems and filtration stations. It is in 28 studied farms within the boundaries of the cities of Semnan province, which were implemented between the years 1389-1400. In evaluating the performance of the mentioned filtration stations, in addition to field visits, two-level questionnaires, statistical analysis and software (Mic Mac-Scenario Wizard) were used. In the first phase, the results of the chemical analysis of water and the performance quality of the stations were calculated separately for 28 farms around TDS, SAR, PH, EC, NA+, Ca+, Mg2+, So42-, Cl- and Hco3- indicators. became At the next level, referring to the findings of the research, it was found that the most water source used by the studied farms was from wells and piped (13 cases, 46.42%). Also, the pistachio crop with the highest level of cultivation (8 cases and 28.5%) has become the dominant crop in the studied fields. In the meantime, the obtained results showed that mesh filtrations with 20 cases (71.40%) were used significantly more than disc filters (8 cases, 28.60%), at the level of the studied filtration stations. It has been used that most of their washing systems were semi-automatic (15 cases, 53.57%), in comparison with other methods. Meanwhile, the most failure of parts in the filtration stations of the studied farms was related to filtration and valves with 9 cases each and 29%. baxsed on the analytical findings of Mik-Mac software, 11 indices A2 (4.89), A4 (4.76), A10 (4.64), A12 (4.63), A3 (4.52), A14 (4.48), A18 (4.46), A6 (4.46), A9 (4.44), A19 (4.42) and A1 (4.40) were identified as the main drivers affecting the hydraulic performance of filtration stations in connection with pressurized irrigation systems. In the following, 4 possible scenarios were calculated and drawn in the form of optimal situation to crisis, and appropriate solutions were presented to improve the performance of filtration stations in 28 farms.
