Mukuita kwekugadziriswa kwemvura yetsvina, inoda kuenda kuburikidza neakateedzana matanho ekushanda, uye mushure mekuedzwa kuti isangane neyakajairwa chiyero, inoburitswa.Mune ino nhevedzano yemaitiro, iyo flocculant inoita basa rakakosha.TheFlocculantinogona flocculate yakaturikwa nyaya maduku mamorekuru mumvura.Kugadzirisa, zvichiita kuti zvive nyore kusefa.Mhando dze flocculants zvakare dzakapfuma kwazvo.Maitiro ekusarudza iyo flocculant inokodzera iwe zvakare yakakosha uye yakakosha.Nezve kusarudzwa kwemaflocculants, PAM nePAC vagadziri vane anotevera mazano:
Nzira yekusarudza flocculant mukurapwa kwemvura yakasviba inofanira kusarudzwa maererano nemaitiro emvura yakasvibiswa mune imwe indasitiri.Panguva imwecheteyo, zvinoenderanawo nekuti iyo flocculant inowedzerwa kupi uye kuti inoshandiswa chii.Kazhinji, pakusarudza inorganic flocculant, kuumbwa kwemvura yakasviba kunofanirwa kutariswa, uye wozosarudza yakakodzera (simbi yemunyu, aluminium munyu kana iron-aluminium munyu, silicon-aluminium munyu, silicon-ferric munyu, nezvimwewo);inorganic polymer flocculants inosanganisira:polyaluminum chloride (PAC), polyaluminium sulfate (PAS), polyaluminium sulfochloride (PACS) uyepolyferric sulfate (PFS), etc. Pakati pavo, iyo yakawanda inomiririra PAC nePAS vane maitiro ekugadzirisa kwakanaka kune kuchinja kwehutano hwemvura inobatwa nemishonga yekurapa mvura yakasvibirira, yakanaka coagulation uye kuchenesa migumisiro, uye mutengo wakaderera wemakemikari.
Paunosarudza organic flocculant (yakadai se:polyacrylamide PAM), zvinonyanya zvinoenderana nekuti anionic polyacrylamide, cationic polyacrylamide kana nonionic polyacrylamide inoshandiswa.Anionic polyacrylamides yakavakirwa pachiyero che hydrolysis.Kusarudzwa kwema cations kunowanzo shandiswa mukubvisa sludge.Kusarudzwa kwe cationic polyacrylamide kwakakosha zvikuru.Zvidyarwa zvemadhorobha ekuchenesa tsvina zvinowanzo shandisa yepakati-yakasimba cationic polyacrylamide.Magetsi asina kusimba anowanzo shandiswa kuchenesa mvura mukugadzira mapepa uye kudhinda nekudhaya zvidyarwa, uye mvura yetsvina yemishonga inowanzoshandiswa.Sarudza cations yakasimba uye zvichingodaro.Mhando imwe neimwe yemvura yakasviba ine maitiro ayo.Non-ionic polyacrylamide inonyanya kushandiswa pasi pemamiriro asina simba ane acidic, uye isiri-ionic PAM inonyanya kushandiswa mukudhinda nekudhaya mafekitori.
Vatengesi vemvura yekuchenesa mvurakurudzira kuti kusarudzwa kwezvose izvi flocculants kunofanirwa kutariswa maererano nebvunzo.Muyedzo, tarisa huwandu hwedosing, tarisa flocculation uye sedimentation kumhanya, kuverenga mutengo wekurapa, uye sarudza inodhura uye inoshanda flocculation agent.
