Reverse Osmosis Water Treatment Plant Automatic Backwash Multimedia Sand Filter

Reverse Osmosis Water Treatment Plant Automatic Backwash Multimedia Sand FilterSand filters are the oldest and most basic form of water filtration and originally consisted of large volumes of sand through which water simply percolated. Modern systems however now include various media layers which allows much more efficient filtration in smaller vessels.Multi-media sand filters normally consist of three media layers (ie. support base gravel, micro screened sand and anthracite) and are a very economical means of primary filtration to remove the bulk of suspended solids. They are particularly efficient on surface waters for the removal of grit, sediment, turbidity and organic matter but also widely used on oxidised iron ('rust') and other precipitated contaminants such as manganese or scale particles.Multi-media filters are periodically backwashed (either automatically or manually) by simply reversing the flow and this flushes to waste the accumulated sediment and also regrades the filter media layers.Operation and maintenance is extremely simple. After initial set-up, the system is virtually self sustaining. With the Performa Head, back-flushing and clearing of trapped contaminates occurs automatically. Filtration taking place through the filtration bed of pressure filters [known as fine filtration] removes especially turbidity, colloid substances, undesirable colour or odour, microbiological contamination, ammonia ions, iron, manganese from water and it reduces water acidity as well  For the purpose of a proper removal of these substances from water and to obtain the requested quality of output water it is necessary to propose a suitable filtration process. The actual filtration through pressure filters is complemented with aeration, clarification, coagulation, static mixers, disinfection The kind of the filtration medium used is very important as well.  Most frequently used filtration fillings:Fine gravel: 1-20mmSilica sand of various roughness: 0.4-2.5mmActive charcoal: is used for absorption of chlorine and other mineral substancesAnthracite: is used in two-layer or multi-layer filtration of drinking water in connection with sand - the addition of anthracite guarantees a longer filter lifetime, it facilitates a larger filtration through-flow and reduces sand contaminationCatalytic mediums are used to remove iron and manganese from drinking waterSemi-burnt Dolomite limestone: is used to reduce water acidityFAQ: 01.  What is the capacity(m3/h or gpm)do you require?02.  How dirty the water is?03.  How the water will be used once it is filtered,04.  And the source of backwash water needed to clean the filters.Specifications:modelFilter diameterHeightinlet-outletFiltration areacapacitymmmmmmm²m³/hourYL-SF-500500816400.26~10YL-SF-600600874400.288~14YL-SF-700700900400.3812~19YL-SF-800800960DN500.5015-25YL-SF-100010001200DN500.7923-39YL-SF-120012001400DN801.1333-55YL-SF-140014001600DN1001.5445-75YL-SF-160016001800DN1002.0160-100YL-SF-180018001950DN1502.5475-125YL-SF-200020002150DN1503.1495-155YL-SF-220022002250DN1503.80115-190YL-SF-240024002100DN1504.52130-210YL-SF-260026002400DN1505.30145-225YL-SF-280028002500DN2006.15155-240YL-SF-300030002600DN2007.00170-255YL-SF-320032002800DN2508.15270-320Package:Our services:We provide 24 hours online customer service.Any inquiry about water treatment system, please feel free to contact me for further details!Contact information:Mobile phone: +86 13585066069Website: http://yldwater.en.made-in-china.comOfficial website: yldwater.en.made-in-china.comGuarantee period:1 yearAfter-sale service:800-827-87-226  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
