Zida zolekanitsa zolimba-zamadzimadzi
Zida zolekanitsa zolimba-zamadzimadzi zimagwiritsidwa ntchito kulekanitsa zolimba ndi zakumwa kuchokera kusakaniza.Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza kuyeretsa madzi oyipa, ulimi, ndi kukonza chakudya.Zida zitha kugawidwa m'mitundu ingapo kutengera njira yolekanitsa yomwe imagwiritsidwa ntchito, kuphatikiza:
1.Zipangizo za sedimentation: Zida zamtundu uwu zimagwiritsa ntchito mphamvu yokoka kuti zilekanitse zolimba ndi zamadzimadzi.Kusakaniza kumaloledwa kukhazikika, ndipo zolimba zimakhazikika pansi pa thanki pamene madzi amachotsedwa pamwamba.
2.Zida zosefera: Zida zamtundu uwu zimagwiritsa ntchito porous medium, monga nsalu ya fyuluta kapena chophimba, kuti alekanitse zolimba ndi zakumwa.Madziwo amadutsa pakati, ndikusiya zolimba kumbuyo.
Zida za 3.Centrifugal: Zida zamtundu uwu zimagwiritsa ntchito mphamvu ya centrifugal kuti ilekanitse zolimba ndi zakumwa.Chosakanizacho chimapota mofulumira, ndipo mphamvu ya centrifugal imapangitsa kuti zolimba zisunthike kumphepete kwakunja pamene madzi amakhalabe pakati.
Zida za 4.Membrane: Zida zamtunduwu zimagwiritsa ntchito nembanemba kuti zilekanitse zolimba ndi zakumwa.Nembanembayo imatha kukhala porous kapena yopanda porous, ndipo imalola madziwo kudutsa ndikusunga zolimba.
Zitsanzo za zida zolekanitsa zolimba zamadzimadzi zimaphatikizapo akasinja otayira, zowunikira, zosefera, ma centrifuges, ndi ma membrane.Kusankha zida zimadalira makhalidwe a osakaniza, monga tinthu kukula, kachulukidwe, ndi mamasukidwe akayendedwe, komanso mlingo chofunika kulekana Mwachangu.
