Chii chinoita PAC mukuchenesa mvura?

Polyaluminium chloride (PAC) inoita basa rakakosha mumagadzirirwo emvura, ichishanda seanoshanda coagulant uye flocculant. Munzvimbo yekucheneswa kwemvura, PAC inoshandiswa zvakanyanya nekuda kwekuenderana kwayo uye kugona mukubvisa tsvina kubva mumatsime emvura. Ichi chemikemikari chikamu chinotamba chakakosha mumatanho ekubatanidza uye flocculation, zvichibatsira kusimudzira kugona kwese kwezvidyarwa zvekuchenesa mvura.

Coagulation ndiyo nhanho yekutanga mukurapa kwemvura, uko PAC inowedzerwa kumvura mbishi. Iwo aruminiyamu anochajiswa zvakanaka maion ari muPAC anoderedza michaji isina kunaka pazvikamu zvakaturikwa mumvura, zvichiita kuti zvibatane. Izvi zvimedu zvakabatana zvinoumba akakura uye anorema aggregates, zvichiita kuti zvive nyore kwavari kugadzikana kunze kwemvura panguva dzinotevera. Iyo coagulation process yakakosha pakubvisa colloidal uye yakamiswa tsvina iyo inogona kunge isiri nyore kusefa.

Flocculation inotevera coagulation uye inosanganisira kubvongodza zvinyoronyoro kana kusanganiswa kwemvura kukurudzira kuumbwa kwezvimedu zvakakura kubva muzvikamu zvakabatana. PAC inobatsira mune ino nhanho nekupa mamwe machaji akanaka, kusimudzira kudhumhana uye kuunganidzwa kwezvimedu kuti zvigadzire zvakakura uye denser flocs. Aya ma flocs anogara zvakanyanya panguva yekunyungudika, zvichiita kuti pave nemvura yakachena.

Imwe yeakanakisa mabhenefiti ePAC mukurapwa kwemvura kuchinjika kwayo kune yakafaranuka yemhando yemvura mamiriro. Inoita zvakanaka munzvimbo dzose dzine acidic uye alkaline, zvichiita kuti ive yakakodzera kurapa kwakasiyana siyana kwemvura. Pamusoro pezvo, PAC inoshanda mukugadzirisa kushanduka kwemvura uye inogona kushandiswa mumashandisirwo akasiyana-siyana ekurapa mvura, kusanganisira kurapwa kwemvura yekunwa, kurapwa kwemvura mumaindasitiri, uye kuchenesa mvura.

PAC inoita basa rakakosha mukugadzirisa kwemvura, kufambisa kubatana uye kuyerera kubvisa tsvina kubva kuzvitubu zvemvura. Kuchinja-chinja kwayo, kushandisa mari, uye mabhenefiti ezvakatipoteredza zvinoita kuti ive chishandiso chakakosha mukutsvaga mvura yakachena uye isina njodzi. Kunzwisisa kukosha kwePAC mukuchenesa mvura kunosimbisa kukosha kwayo mukugadzirisa matambudziko emhando yemvura pasi rose.
