Evaluation and Comparison of Performance in the Disc Filter with Sand Filters of Filtration Equipment in Micro Irrigation Systems

At the present time, the need to evacuate organic and green growth of algae contaminants in  micro irrigation system is expanding increasingly. The worldwide populace is expanding and as a result of this, the world may encounter extraordinary fresh water shortage. Our water assets are constrained and, subsequently, water treatment and reusing strategies are the main choices for getting crisp and fresh water in the coming decades. This study examines the rate of the impact of green growth of algae existing in micro irrigation system performance on the disc filters and sand tanks in the examination field of water, soil and horticultural and agricultural commercial enterprises Vice-Presidency of Karaj.The analyses were performed in four scenarios comprising of ordinary disc filter together with sand tank, automated disc filter together with sand tank, automated disc filter without sand tank lastly common ordinary disc filter without sand tank. These scenarios were assessed and looked at in three classifications of physical quality of irrigation system water. Data collection and experiments was run up to three months. The results of the experiments demonstrated that concentration of organic and suspended materials is viewed as safe for low flow emitters. In the range of 50 through 100 mg per liter, automated disc filters represented a good performance. In the concentration of 100 mg/l or higher, the performance of disc filters significantly decreased; subsequently it is important to put the sand tank before disc filters.
