Polyacrylamide(PAM) ipolymer yakagadzirwa ne hydrophilic inoshandiswa zvakanyanya mukurapa mvura. Inonyanya kushandiswa se flocculant uye coagulant, kemikari inokonzera kuti zvidimbu zvakasungirirwa mumvura zviungane kuita flocs hombe, nokudaro zvichibatsira kubviswa kwadzo kuburikidza nekucheneswa kana kusefa. Zvichienderana nemhando yemvura yakasviba, shandisa cationic, anionic, kana non-ionic PAM. Polyacrylamide ine mabhenefiti akati wandei mukurapa mvura, kusanganisira kushanda kwayo pamusoro pemhando dzakasiyana dze pH, tembiricha, uye turbidity. Mhedzisiro yekuomesesa inogona kuyedzwa uchishandisa Jar tests kana turbidity measurement.
Polyacrylamide inogona kushandiswa zvakanyanya mukuchenesa mvura mumaindasitiri, kugadzirisa tsvina, kugadzirisa mvura yakasviba, nezvimwewo. Mumafekitori ekuchenesa mvura, polyacrylamide inoshandiswa mumabasa akasiyana-siyana, anosanganisira kujekesa kwekutanga nekwechipiri, kusefa, uye kuuraya utachiona. Munguva yekujekesa kwekutanga, inowedzerwa mumvura isina kucheneswa kuti isimudzire kugadzika kwemvura yakaomeswa, iyo inozobviswa nekusefa kana kudonha. Mukuchenesa kwechipiri, polyacrylamide inoshandiswa kujekesa mvura yakaomeswa nekubvisa yakasara yakaomeswa uye zvinhu zvakasikwa zvakanyungudutswa.
Nheyo yekushanda kwepolyacrylamide flocculantndeichi: mushure mekuwedzera mushonga wePAM, PAM inonamira pazvidimbu, ichigadzira mabhiriji pakati pazvo. Mudziva rekutanga, rinonamira kuti rigadzire mafloc akakura, uye mvura inova nematope panguva iyi. Mushure mekunge huwandu hwakawanda hwemafloc hwakura uye hwakora, hunotama uye hunonyura zvishoma nezvishoma nekufamba kwenguva, uye chikamu chepamusoro chemvura isina kucheneswa chichava chakajeka. Maitiro aya ekuunganidza anovandudza hunhu hwemafloc, zvichiita kuti zvive nyore kubvisa panguva yekucheneswa kana kusefa. Polyacrylamide inowanzo shandiswa pamwe chete nedzimwe coagulants neflocculants kuti iwane kujeka kwakanyanya uye kushanda zvakanaka kwekusefa.
Polyacrylamide ine basa rakakosha mukusefa mvura. Inowanzo shandiswa sefa yekutanga mumafirita kana dzimwe nzira dzekusefa panyama kubvisa zvinhu zvakaoma zvakasungirirwa uye matope. Nekuvandudza kubviswa kwezvidimbu izvi, polyacrylamide inobatsira kuve nechokwadi chekuti filtrate yakajeka uye yakachena.
Polyacrylamide ipolymer yakasimba uye isina chepfu inoputsika kuburikidza nemaitiro echisikigo kana nzira dzekurapa dzezvipenyu. Zvinofanira kucherechedzwa kuti mvura yakadururwa ichaita kuti pasi ritsvedze zvakanyanya, izvo zvinogona kukonzera kudonha.
Zvisinei, huwandu hwePAM hunoshandiswa hunoenderana nerudzi rwemvura yakasviba uye huwandu hwezvinhu zvakasungirirwa, pamwe nekuvapo kwemamwe makemikari, maasidhi, uye zvinosvibisa mumvura. Zvinhu izvi zvinogona kukanganisa kuvharika kwePAM, saka kugadzirisa kwakakodzera kunofanirwa kuitwa panguva yekushandiswa. Zvigadzirwa zvePAM zvine huremu hwakasiyana hwemamorekuru, madhigirii eionic, uye madosi zvinofanirwa kusarudzwa nokungwarira kune marudzi akasiyana emvura yakasviba.
