Agricultural Water Purifier

Automatic Sand Filter for Drip Irrigation Product DescriptionBrief introductionSand filter system includes tanks with under drain system, backwash valve, piping, and automatic control system.DMF filters are designed for the most challenging dirty water conditions, with a high-performance solution for water filtration down to 20 microns. These durable carbon steel filters utilize a 24"-54" vertical side shell depth for the removal of organic and inorganic suspended solids for filtering large volumes of water with very little pressure drop and a long-term value. ApplicationCommercial - Golf course and sporting field irrigation systems.Industrial  - Pre-preteatment of UF/RO and wastewater recycling.Irrigation - Primary filtration for the prevention of blockages in the irrigation systemHVAC- cooling tower side filtration and full systemMetal Processing Plants - Filtration for water cooling and spray nozzles.Mining - Cleaning of process and waste water.If you need sand filter for agricultural irrigation, please select model as below.(40 micron) ModelVessel qualitiesFlow(min.)(m3/h)Flow(max.)(m3/h)Filtration area(m2)Backwash flow(single vessel)(m3/h)Pressure(max.)(Bar)Water in/outBackwash pipeDMF-2016-1A1813.50.213.582"2"DMF-2416-1A113.5220.282282"2"DMF-2016-2A216270.413.582"2"DMF-2816-1A118300.383083"3"DMF-2416-2A227440.562283"2"DMF-3616-1A128500.645083"3"DMF-2816-2A236600.773084"3"DMF-2416-3A340.5660.852283"3"DMF-4816-1A150851.138584"4"DMF-2816-3A354901.153084"3"DMF-3616-2A2561001.285084"3"DMF-3616-3A3841501.925086"3"DMF-4816-2A21001702.268586"4"DMF-4816-3A31502553.398588"4"DMF-4816-4A42003404.528588"4"DMF-4816-5A52504255.6585810"4"DMF-4816-6A63005106.7885810"4"Working principleThe Filtering ProcessFiltering with media filters, also known as depth filtration, is done by filtering water through a thick layer of graded particles, called the filter bed. These particles can be sand, gravel or other granular materials. The filtration degree depends on the effective size of the bedding and the water velocity through the filter. Raw water enters from the filter inlet (1) and percolates through the filter bed (2). Suspended materials come into contact and attach to the media particles. Clean water flows through the filtration nozzles (3) and out of the filter via the outlet valve (4). The gradual dirt buildup in the filter bed causes an increase in the pressure differential across the filter and when it reaches its maximum design value, a cleaning process should be performed. In automatic media filter installations a pressure differential switch senses the pressure differential and when it reaches a preset value, the self cleaning process begins.            Technical requirements            Min. pressure: 0.15Mpa           Max. pressure: 1.0Mpa            Working temperature:
