Filter media hi filtration system "thinlung" a ni a, a performance hian direct takin filtration efficiency leh operating cost a tichiang a ni. Material leh purpose ang zelin chi thum-ah then theih a ni a, chungte chu:
1. Granular Filter Media: quartz sand (particle size 0.5-1.2mm), anthracite (density 1.4-1.8g/cm3), tui thianghlimna atana suspended solids interception atana tha
2. Porous filter media: activated carbon (saper area bik 1000m2/g aia tam emaw, a tlukpui emaw), organic matter adsorption leh decolorization atana hman thin
3. Fiber Filter Media: polyester fiber (porosity 90% aia tam emaw, a tlukpui emaw), high-precision air filtration atan a tha.
Professional Research (Journal of Environmental Engineering 2022) chuan filter media thlan hian interception capacity (quartz sand filter bed-a interception capacity chu 15kg/m3 a thlen theih ang chi) leh backwash regeneration performance (backwash intensity hi 10-15L/(m2·s) a ni tlangpui) chu a dah pawimawh ber tur a ni tih a tarlang.
