Kuyerera kwemvurainzira inoshandiswa mumaindasitiri akasiyana-siyana, kunyanya mukurapa mvura uye kurapwa kwemvura yakasviba, kuunganidza zvidimbu zvakamiswa uye colloids kuita zvidimbu zvakakura zve floc. Izvi zvinoita kuti zvibviswe kuburikidza nekusefa kana kupfapfaidza. Mishonga inoshandiswa pakupfapfaidza inozivikanwa se flocculants. Imwe yeflocculants inonyanya kushandiswa uye inoshandiswa zvakanyanya i polyacrylamide.
Polyacrylamideipolymer yakagadzirwa kubva kuacrylamide monomers. Inowanikwa mumhando dzakasiyana-siyana, kusanganisira anionic, cationic, uye non-ionic, imwe neimwe ine mashandisirwo chaiwo. Sarudzo yemhando yepolyacrylamide inoenderana nemhando yezvidimbu zviri mumvura uye mhedzisiro inodiwa ye flocculation process.
Anionic polyacrylamide ine chaji isina kunaka uye inowanzoshandiswa mukurapa mvura yakasviba ine zvidimbu zvakatsvairwa zvakanaka zvakaita sevhu ne organic matter. Cationic polyacrylamide, kune rumwe rutivi, ine chaji yakanaka uye inoshanda pakurapa mvura nezvidimbu zvakatsvairwa zvisina kunaka zvakaita se suspended solids ne sludge. Non-ionic polyacrylamide haina chaji uye yakakodzera kutenderera kwezvikamu zvakasiyana-siyana.
Maflocculant ePolacrylamide anoshanda nekunamira pamusoro pezvikamu, zvichigadzira mabhiriji pakati pazvo, uye kugadzira maaggregates makuru. Mafloc anobuda ari nyore kugadzika kana kusefa kubva mumvura. Polyacrylamide inofarirwa nekuda kwehuremu hwayo hwakawanda hwemamorekuru, izvo zvinowedzera kugona kwayo kudzikamisa nekudzikamisa.
Kunze kwepolyacrylamide, mamwe makemikari anoshandiswawo pakusanganisa makemikari, zvichienderana nezvinodiwa nemaitiro ekurapa.Aruminiyamu Sulfate(alum) uye ferric chloride, zvinowanzo shandiswa pakuchenesa mvura. Makemikari aya anoumba simbi hydroxide flocs kana ikaiswa mumvura, zvichibatsira kubvisa zvidimbu zvakasungirirwa.
Alum, kunyanya, yave ichishandiswa zvakanyanya pakucheneswa kwemvura kwemakore mazhinji. Kana ikaiswa mumvura, alum inonyungudika, ichigadzira aruminiyamu hydroxide flocs inosunga tsvina. Maflocs anogona kugadzikana, uye mvura yakacheneswa inogona kuparadzaniswa netsvina.
Kugadzira mvura inoyerera (flocculant) idanho rakakosha mukugadzirisa mvura, zvichiita kuti tsvina ibviswe uye mvura yakachena ibudiswe. Kusarudzwa kwemuchina wekuchenesa mvura kunoenderana nezvinhu zvakaita sehunhu hwemvura inofanira kurapwa, rudzi rwezvidimbu zviripo, uye mhedzisiro yekurapa inodiwa. Polyacrylamide nezvimwe zvinhu zvinofambisa mvura zvinotamba basa rakakosha mukusimudzira kushanda zvakanaka kwemvura uye nzira dzekuchenesa mvura yakasviba, zvichibatsira mukupa mvura yakachengeteka uye inonwiwa kune zvinangwa zvakasiyana-siyana.
