Kana uchitengaPolyaluminum Chloride(PAC), chinhu chinoshandiswa zvakanyanya mukurapa mvura, zviratidzo zvakakosha zvakawanda zvinofanirwa kuongororwa kuti ive nechokwadi chekuti chigadzirwa ichi chinosangana nezvinodiwa uye chakakodzera kushandiswa kwacho. Heano zviratidzo zvikuru zvekutarisa pazviri:
1. Zviri MuAruminiyamu
Chinhu chikuru chinoshanda muPAC iaruminiyamu. Kushanda kwePAC sechinhu chinobatanidza mvura kunonyanya kuenderana nehuwandu hwearuminiyamu. Kazhinji, huwandu hwearuminiyamu muPAC hunoratidzwa sechikamu cheAl2O3. PAC yemhando yepamusoro inowanzova ne28% kusvika 30% yeAl2O3. Hunhu hwearuminiyamu hunofanira kukwana kuti ive nechokwadi chekuti kuomeswa kwemvura kunoshanda pasina kushandiswa zvakanyanya, izvo zvinogona kukonzera kusashanda zvakanaka kwemari uye migumisiro yakaipa pahunhu hwemvura.
2. Zvakakosha
Basicity chiyero chehuwandu hwehydrolysis yemhando dzearuminiyamu muPAC uye chinoratidzwa sechikamu. Chinoratidza chiyero chemaion ehydroxide kune aruminiyamu mumushonga. PAC ine basicity range ye40% kusvika 90% inowanzo shandiswa pakurapa mvura. Basicity yepamusoro inowanzo reva kuti mvura inoshanda zvakanyanya asi inofanira kuenzaniswa nezvinodiwa zvekurapa mvura kudzivirira kunyanyisa kana kusanyanya kucheneswa.
4. Matanho Ekusachena
Kuvapo kwetsvina dzakadai sesimbi dzinorema (semuenzaniso, lead, cadmium) kunofanira kunge kushoma. Tsvina idzi dzinogona kukonzera njodzi kuhutano uye kukanganisa mashandiro ePAC. PAC yakachena kwazvo ichave nemazinga akaderera etsvina yakadaro. Mapepa ekufananidzira anopiwa nevagadziri anofanira kusanganisira ruzivo pamusoro pehuwandu hwakanyanya hwetsvina idzi.
6. Chimiro (Chakaoma kana Chakaita Mvura)
PACinowanikwa mumhando dzakasimba (hupfu kana granules) uye dzemvura. Sarudzo pakati pemhando dzakasimba nedzemvura inoenderana nezvinodiwa nefekitari yekurapa, kusanganisira nzvimbo dzekuchengetera, michina yekuyedza, uye nyore kubata. PAC yemvura inowanzo sarudzwa nekuda kwekushandiswa kwayo nyore uye kunyungudika nekukurumidza, nepo PAC yakasimba inogona kusarudzwa nekuda kwekuchengetedza kwenguva refu uye mabhenefiti ekufambisa. Zvisinei, hupenyu hwesherufu yemvura hupfupi, saka hazvikurudzirwi kutenga mvura zvakananga kuti uichengete. Zvinokurudzirwa kutenga yakasimba woigadzira wega zvichienderana nehuwandu hwayo.
7. Hupenyu hweSherufu uye Kugadzikana
Kugadzikana kwePAC nekufamba kwenguva kunokanganisa mashandiro ayo. PAC yepamusoro-soro inofanira kugara kwenguva refu, ichichengetedza hunhu hwayo uye kushanda kwayo kwenguva yakareba. Mamiriro ekuchengetera, akadai sekupisa uye kusvibiswa nemhepo, anogona kukanganisa kugadzikana, saka PAC inofanira kuchengetwa munzvimbo inotonhorera, yakaoma mumidziyo yakavharwa kuti ichengetedze kunaka kwayo.
8. Kushanda Nemutengo Wakanaka
Pamusoro pemhando yezvigadzirwa, zvakakoshawo kufunga nezvekushandisa mari zvakanaka pakutenga. Enzanisa mitengo, kurongedza, kutakurwa, nezvimwe zvinhu zvevatengesi vakasiyana kuti uwane zvigadzirwa zvine kushanda zvakanaka pamutengo.
Muchidimbu, pakutenga polyaluminum chloride, zvakakosha kufunga nezvehuwandu hwearuminiyamu, kukosha kwayo, pH, mwero wekusvibiswa kwayo, kunyunguduka kwayo, chimiro chayo, nguva yayo yekushanda, kushanda kwayo, uye kutevedzera mitemo. Zviratidzo izvi pamwe chete zvinosarudza kukodzera uye kushanda kwePAC pakushandisa mvura yakasiyana-siyana.
