Ndezvipi zviratidzo zvikuru zvekutarisa kana uchitenga Polyaluminium Chloride?

PakutengaPolyaluminium Chloride(PAC), coagulant inoshandiswa zvakanyanya mumagadzirirwo emvura, akati wandei akakosha zviratidzo zvinofanirwa kuongororwa kuti ive nechokwadi chekuti chigadzirwa chinosangana nezvinodiwa uye chakakodzera kushandiswa kwacho. Pazasi pane zviratidzo zvikuru zvekutarisa pa:

1. Aluminium Content

Chinhu chekutanga chinoshanda muPAC ialuminium. Kushanda kwePAC secoagulant zvakanyanya kunoenderana nekuwanda kwealuminium. Kazhinji, iyo aluminium yemukati muPAC inoratidzwa sechikamu cheAl2O3. Yepamusoro-mhando PAC kazhinji ine pakati pe28% kusvika 30% Al2O3. Iyo aruminiyamu yemukati inofanirwa kuve yakakwana kuti ivimbise kugwinya kunoshanda pasina kushandisa zvakanyanya, izvo zvinogona kutungamira mukusashanda zvakanaka kwehupfumi uye zvinogona kukanganisa mhedzisiro pamhando yemvura.

2. Basicity

Basicity chiyero chechiyero che hydrolysis yemhando yealuminium muPAC uye inoratidzwa sechikamu. Inoratidza chiyero che hydroxide kune aluminium ions mune mhinduro. PAC ine basicity range ye 40% kusvika 90% inowanzo diwa pakuchenesa mvura. Hunhu hwepamusoro hunowanzo reva kubatana kwakanyatso shanda asi hunofanirwa kuenzana nezvinodiwa chaizvo zvemagadzirirwo emvura kudzivirira kunyanya kana kusanyanya kurapwa.

4. Kusachena Levels

Kuvepo kwetsvina senge heavy metal (semuenzaniso, lead, cadmium) kunofanirwa kuve kushoma. Izvi zvinosvibisa zvinogona kukonzera njodzi dzehutano uye kukanganisa kushanda kwePAC. High-purity PAC ichange iine mwero wakaderera zvikuru wezvinosvibisa zvakadaro. Mapepa ekutsanangurwa anopihwa nevagadziri anofanirwa kusanganisira ruzivo rwepamusoro-soro inotenderwa yezvitsvina izvi.

6. Fomu (Rakasimba kana Liquid)

PACinowanikwa mune zvese zvakasimba (hupfu kana granules) uye mafomu emvura. Sarudzo pakati pemafomu akasimba uye emvura zvinoenderana nezvinodiwa chaizvo zvechirimwa chekurapa, zvinosanganisira nzvimbo dzekuchengetera, dosing michina, uye nyore kubata. Liquid PAC inowanzo diwa kuitira nyore kushandisa uye kukurumidza kunyungudika, nepo PAC yakasimba inogona kusarudzirwa kuchengetedza kwenguva refu uye mabhenefiti ekufambisa. Nekudaro, iyo sherufu yehupenyu hwemvura ipfupi, saka hazvikurudzirwe kutenga mvura yakananga kuchengetedza. Zvinokurudzirwa kutenga zvakasimba uye kuzviita iwe pachako maererano nehuwandu.

7. Sherufu Hupenyu uye Kugadzikana

Kugadzikana kwePAC nekufamba kwenguva kunokanganisa kuita kwayo. Yepamusoro-mhando PAC inofanirwa kuve nehupenyu hwakasimba hwesherufu, ichichengetedza zvivakwa zvayo uye kushanda kwayo kwenguva yakareba. Mamiriro ekuchengetedza, akadai sekushisa uye kuratidzwa nemhepo, anogona kukanganisa kugadzikana, saka PAC inofanira kuchengetwa munzvimbo inotonhorera, yakaoma mumidziyo yakavharwa kuchengetedza kunaka kwayo.

8. Mutengo-Kubudirira

Pamusoro pemhando yechigadzirwa, inofanirwawo kufunga nezve mutengo-kubudirira kwekutenga. Enzanisa mitengo, kurongedza, zvekufambisa, uye zvimwe zvinhu zvevatengesi vakasiyana kuti uwane zvigadzirwa zvine mutengo wakakodzera.

Muchidimbu, kana uchitenga polyaluminium chloride, zvakakosha kufunga nezve aruminiyamu yemukati, basicity, pH kukosha, kusachena mazinga, kunyungudika, fomu, hupenyu hwesherufu, mutengo-unoshanda, uye kutevedzera mutemo. Aya zviratidzo pamwe chete anoona kukodzera uye kugona kwePAC kune akasiyana siyana ekuchenesa mvura.
