Zosefera zokhala ndi laminated, mapepala owonda amtundu wina wa pulasitiki wokhala ndi ma grooves amtundu wina wa micron wokhazikika mbali zonse.Mulu wapatani womwewo umakanikizidwa motsutsana ndi chingwe chopangidwa mwapadera.Mukapanikizidwa ndi kasupe ndi kuthamanga kwamadzimadzi, ma groove pakati pa mapepala amawoloka kuti apange gawo lakuya la fyuluta ndi njira yapadera ya fyuluta.Sefayi imayikidwa mu silinda yamphamvu yaukadaulo yaukadaulo ya pulasitiki kuti ipange fyulutayo.Mukasefa, mulu wa fyuluta umakanizidwa ndi kuthamanga kwa masika ndi madzimadzi, kusiyana kwakukulu kwa kuthamanga, mphamvu yopondereza imakhala yamphamvu.Onetsetsani kuti mukudzikhoma kusefera koyenera.Madziwo amayenda kuchokera m'mphepete mwa kunja kwa laminate kupita m'mphepete mwa mkati mwa laminate kupyolera mu poyambira, ndipo amadutsa 18 ~ 32 filtration point, motero amapanga kusefa kwapadera kwapadera.Fyulutayo ikatha, kuyeretsa pamanja kapena kuchapa mmbuyo kutha kutheka mwa kumasula pakati pa mapepala pamanja kapena pamadzi.
