Nheyo yekushanda yebhegi sefa
Nheyo yekushanda yebhegi sefa
1. Kudyisa: Mvura inopinda mugoko rebhegi sefa kuburikidza nepombi inopinza.
2. Filtration: Kana mvura ichipfuura nepakati pesefa bhegi, tsvina, zvimedu, uye zvimwe zvinhu zvinopepetwa kunze nemapores ari pabhegi resefa, nokudaro zvichizadzisa chinangwa chekuchenesa mvura. Mabhegi emasefa emabhegi mafirita anowanzo kugadzirwa nezvinhu zvakadai sepolyester, polypropylene, nylon, polytetrafluoroethylene, etc. Zvinhu zvakasiyana-siyana zvemabhegi emasefa zvine kurongeka kwakasiyana-siyana uye kusagadzikana kwekuora.
3. Kuburitsa: Mvura yakasefa nebhegi resefa inoyerera ichibuda mupombi yekubuda nayo yesefa yebhegi, ichizadzisa chinangwa chekuchenesa.
4. Kuchenesa: Kana tsvina, zvimedu, uye zvimwe zvinhu zvakaungana kusvika pamwero wakati pabhegi resefa, zvinodikanwa kuchenesa kana kutsiva bhegi resefa. Masefa ebhegi anowanzo shandisa nzira dzakaita sekufuridza kumashure, kugeza mvura, uye kuchenesa mabhegi kuchenesa mabhegi.
Zvakanakira mabhegi mafirita zvakanaka kusefa kunyatsoita, kushanda kuri nyore, uye kugadzirisa kuri nyore. Bag mafirita akakodzera maindasitiri akadai semakemikari, mishonga, chikafu, chinwiwa, zvemagetsi, semiconductor, machira, papermaking, metallurgy, petroleum, gasi rechisikigo, etc. Izvo zvinoshandiswa zvakanyanya pakusefa uye kucheneswa kwezvinwiwa nemagasi.
