Munyaya yekuchenesa mvura, kutsvaga mvura yakachena uye yakachengeteka ndiko kunonyanya kukosha. Pakati pezvishandiso zvakawanda zviripo pabasa iri,polyacrylamide(PAM), inozivikanwawo se coagulant, inoonekwa semushonga unoshanda zvakasiyana-siyana. Kushandiswa kwayo mukurapa kunovimbisa kubviswa kwetsvina nezvinhu zvinosvibisa, nokudaro zvichivandudza kunaka kwemvura yekunwa. Chinyorwa chino chinotsanangura mashandisirwo akasiyana-siyana epolyacrylamide mukurapa mvura yekunwa, zvichitsanangura basa rayo sechinhu chakakosha mukuchenesa.
1. Kubatana kweropauye Flocculation
Imwe yenzira huru inoshandiswa nepolyacrylamide mukurapa mvura yekunwa ndeyekuonda nekupwanya. Kupwanya kunosanganisira kudzikamisa zvidimbu zvecolloidal kuburikidza nekuwedzera makemikari, zvichiita kuti zviungane. Polyacrylamide inobatsira mukuita uku nekuderedza simba remagetsi pazvidimbu zvakamiswa, zvichiita kuti zviungane kuita zvidimbu zvakakura, zvinogadzikana. Zvadaro, kupwanya kunoita kuti zvidimbu zvakakura uye zvakamanikana zviumbwe, izvo zvinogona kubviswa nyore nyore kuburikidza ne sedimentation kana sefiltration processes.
2. Kubviswa Kwakawedzerwa Kwezvinhu Zvinosvibisa
Polyacrylamide inowedzera kushanda zvakanaka kwekubvisa tsvina dzakasiyana-siyana dziri mumvura yekunwa. Nekubatsira kuumbwa kweflocs hombe, inovandudza nzira dzekusefa nekunyungudutsa, zvichiita kuti zvinhu zvakasimba zvakamiswa, zvinhu zvipenyu, uye tupukanana zvibviswe zvakanaka. Pamusoro pezvo, PAM inobatsira mukubvisa simbi dzinorema, dzakadai se lead ne arsenic, nekugadzira ma complexes ane aya ma ions, nokudaro ichidzivirira kupararira kwawo mumvura yakarapwa.
3. Kuderedza Kusviba Kwemhepo
Kusviba, kunokonzerwa nezvidimbu zvakasungirirwa mumvura, hakungokanganisi runako rwemvura yekunwa chete asiwo kunoshanda sechiratidzo chehunhu hwemvura. Polyacrylamide inoderedza kusviba zvinobudirira nekukurudzira kuunganidzwa kwezvidimbu zvidiki kuita maflocs makuru, ayo anogadzikana nekukurumidza. Izvi zvinoguma nemvura yekunwa yakajeka uye inoyevedza, ichisangana nezvinodiwa nemutemo uye zvinotarisirwa nevatengi.
Mukupedzisa, polyacrylamide (PAM) inoita basa guru mukurapa mvura yekunwa, ichipa mabhenefiti akawanda maererano neKubatana kweropa, kubvisa tsvina, kuderedza kusviba kwemvura, kubvisa algae, uye kugadzirisa pH. Hunhu hwayo hunoshandiswa zvakasiyana-siyana uye kushanda kwayo kunoita kuti ive chishandiso chakakosha kumafekitori ekurapa mvura ari kuedza kupa mvura yakachena, yakachengeteka, uye inoyevedza kune vatengi. Sezvo kufambira mberi muhunyanzvi hwekurapa mvura kuri kuramba kuchichinja, polyacrylamide yakagadzirira kuramba iri chinhu chakakosha mukutsvaga kwekutarisira mvura kwenguva refu uye kuchengetedzwa kwehutano hweveruzhinji.
