1. Udindo wa zosefera media
Zosefera zosefera zimatanthawuza zinthu zomwe zimagwiritsidwa ntchito kusefa, kulekanitsa ndi kuyeretsa zinthu, ndipo zimagwiritsidwa ntchito kwambiri poyeretsa madzi, kukonza mpweya, makampani opanga mankhwala ndi zina. Zosefera zosefera zimatha kuchita nawo sefa, kulekanitsa, kutsatsa, ndi zina zambiri, ndipo zimatha kuchotsa bwino zinthu zomwe zaimitsidwa, chromaticity, zonyansa, fungo, zomera za bakiteriya ndi zinthu zina zovulaza m'madzi kuti zitsimikizire chitetezo chamadzi; nthawi yomweyo, imathanso kuchotsa zowononga mumlengalenga ndikuwongolera mpweya wabwino.
Pochiza madzi, zosefera zosefera zimagwiritsidwa ntchito kwambiri kusefa kwambiri, kuyeretsa madzi komanso kuyeretsa zimbudzi. Pochiza mpweya, zosefera zitha kugwiritsidwa ntchito kusefera mpweya, kuchotsa fumbi ndi zina. Kuphatikiza apo, zosefera zosefera zimagwiritsidwanso ntchito kwambiri m'mafakitale, mankhwala, chakudya ndi mafakitale ena, ndipo ntchito zawo zimaphatikizapo kulekanitsa, kuyeretsa, kutsatsa, kubwezeretsanso, ndi zina zambiri.
2. Mitundu ndi zochitika zogwiritsira ntchito zosefera
A. Mchenga zosefera media
Zosefera za mchenga ndizoyenera kuyeretsa madzi apampopi, kutsuka zimbudzi, kuyeretsa zinyalala, kuyeretsa dziwe ndi zina. Ntchito yake ndikugwiritsa ntchito kukula kwa pore kwa magawo angapo a zosefera kuti alekanitse zonyansa ndi zinthu zina m'madzi kuti madziwo amveke bwino.
B. Zida zosefera mpweya
Activated carbon filter material ndi organic adsorption zinthu zomwe zimagwiritsidwa ntchito poyeretsa madzi akumwa, kuyeretsa madzi oyipa, kuyeretsa mpweya ndi zina. Ntchito yake ndikuchotsa zowononga monga fungo, mtundu, organic zinthu m'madzi, komanso fungo ndi mpweya woipa mumlengalenga.
C. Zida zosefera CHIKWANGWANI
Fiber filter material ndi-zosefera bwino kwambiri zomwe zimagwiritsidwa ntchito popanga mankhwala, mankhwala, chakudya ndi zina. Ntchito yake ndikusefa tinthu ting'onoting'ono tamadzimadzi ndikuchotsa tizilombo toyambitsa matenda monga mabakiteriya ndi ma virus.
