Polydimethyl diallyl ammonium chloride (PDMDAAC) mushonga wekuchenesa mvura usingadhuri uye unoshanda zvakasiyana-siyana unogona kutsiva mishonga yakawanda yechinyakare mumamiriro akasiyana-siyana, zvichipa zvakanakira zvikuru zvakaita sekuvandudzwa kwemhando, kuderedzwa kwemitengo, uye kuwedzera kushanda zvakanaka. Inogona kutsiva mishonga inobvisa ruvara senge polyferric sulfate nepolyaluminum chloride, pamwe ne activated carbon, ine dose ye1/3 chete yemishonga yechinyakare, zvichikonzera kuderedzwa kwemavara uye kuderedzwa kwehafu yekugadzirwa kwetsvina. Inogona kurapa mhando dzakasiyana dzemvura inoraswa nedhayi, zvichideredza zvakanyanya mari yekurasa tsvina.
Panguva imwe chete, inogona kutsiva PAM yetsika yecationic, ichipa mitengo yakaderera, kunyunguduka kuri nani, uye kushanda kuri nyore panguva imwe chete yecationionic. Kushandiswa pamwe chete kunogona kuderedza mitengo yemushonga ne30%, uye kunogona kutsiva zvachose mamiriro ekunze ekubviswa kwemvura. Uyezve, inogona kutsiva macoagulants emunyu wealuminium akadai sealum nepolyaluminum sulfate, asingakanganisike nekupisa kwemvura, achigadzira maflocs akaomarara, anokurumidza kugadzikana, achibvisa matambudziko ealuminium residue, uye achigadzirisa hunhu hwetsvina.
Inogonawo kusanganiswa neupfu hwesimbi kuti itsive lime inogadzirisa tsvina, pasina kuwedzera huwandu hwetsvina, kusasiya tsvina, uye kurerutsa kurapwa kwemvura. Kunyangwe tsvina yakaoma ichida zvinhu zvinosanganisa mvura, kushanda kwayo kwese kunodarika kwemishonga yechinyakare. Munguva ino yekudzora mitengo zvakanyanya uye kutsvaga tsvina yakagadzikana, PDMDAAC, ine mabhenefiti ayo akawanda emuyero wakaderera, kugadzirwa kwetsvina kwakaderera, mhedzisiro yakagadzikana, uye nyore kushanda, yave sarudzo inosarudzwa yekuvandudza nzvimbo huru dzekuchenesa mvura yakasviba nemvura kuti dzitsive zvinhu zvechinyakare, zvichiita kuti zvive nyore kugadzirisa hunhu hwekuchenesa mvura uye kuderedza mitengo.
