Mumunda wekurapwa kwemarara, zvese polandauminum chloride (pac) uye aluminium sulfate inoshandiswa zvakanyanya seCoagulants. Pane misiyano mune yemakemikari chimiro chevamiriri vaviri ava, zvichikonzera kuita kwavo kuita uye kushandisa. Mumakore achangopfuura, Pac akafarirwa zvishoma nezvishoma nezvekurapwa kwayo kukurukurirana uye nekumhanya. Munyaya ino, isu tichakurukura nezve misiyano pakati pePac uye aluminium sulfate kurapwa kwemarara kukubatsira kuti uite sarudzo yakaziviswa.
Chekutanga, ngatidzidze nezvePolandauminum chloride (pac). Semunhu inormacanic polymer coaguulant, pac ine yakanakisa salubility uye inogona kukurumidza kuumba flocs. Iyo inotora chikamu chekubatana kuburikidza nekusarerekera uye mambure trapping, uye inoshandiswa mukubatana neye floculant pam kuti ubvise zvisingabatsiri mumarara. Kuenzaniswa neAluminium Sulfate, Pac ine simba rakasimba rekugadzirisa uye zviri nani mvura yemvura mushure mekunatswa. Zvichakadaro, mutengo wekucheneswa kwemvura kwePac ndeye 15% -30% yakaderera pane aluminium sulfate. Panyaya yekuparadza alkalinity mumvura, pac ine kuderera kwekushandisa uye inogona kuderedza kana kudzima jekiseni reAlkaline mumiririri.
Inotevera is aluminium sulfate. Semunhu echinyakare, aluminium sulfate adsorbs uye anobatanidza pllutants kuburikidza aluminium hydroxide colloids yakagadzirwa ne hydrolysis. Chiyero charo chinyungudika chakaringana, asi chakakodzera kurapwa kwemarara nePH ye6.0-7.5. Kuenzaniswa nePac, Aluminium Sulfate ine hunhu hwakacheneswa uye hwakacheneswa mvura, uye mutengo wekunatswa kwemvura zvakakwirira.
Panyaya yekuita zviyero, pac uye aluminium sulfate ine zvishoma zvinoshandiswa zvinoshandiswa; Pac kazhinji iri nyore kubata uye maficha flocs nekukurumidza, iyo inovandudza kushanda kwekurapa. Aluminium Sulfate, kune rumwe rutivi, inononoka kuHydrolyze uye inogona kutora nguva yakareba kuti ibate.
Aluminium SulfateNdichaderedza iyo pH uye alinboility yemvura yakabatwa, saka soda kana lime inodiwa kuti tisaradzire mhedzisiro. Pac Solution iri padyo neasina kwayakarerekera uye pasina chinodiwa kune chero kusarerekera mumiriri (soda kana lime).
Panyaya yekuchengetedza, pac uye aluminium sulfate inowanzogadzikana uye nyore kuchengeta nekutakura. Nepo pac ichifanira kusimbiswa kuti vadzivise kunyorova uye kuratidzwa kwezuva.
Mukuwedzera, kubva pane maonero ekunyora, aluminium sulfate zviri nyore kushandisa asi zvimwe zvinokatyamadza. Kana uchisarudza kabhuku, maitiro anogona kuita zvese pamidziyo yekurapa inofanirwa kunyatsofungidzirwa zvizere.
Mukupfupikisa,Polandauminum chloride. Kupfuura, Pac kuri kuita zvishoma nezvishoma kuwirirana kukuru nekuda kwekunyanyisa kugona, kukurumidza marara kurapwa kwekurapa kugona uye yakafara pH. Nekudaro, aluminium sulfate ichine zvisinga tsanangurike zvakanakira pasi pemamwe mamiriro. Naizvozvo, kana uchisarudza kanokona, zvinhu zvakadai sekuda chaiko, maitiro ekurapa uye mutengo unofanirwa kutariswa. Kusarudza kanokwana kurudyi kuchabatsira kuvandudza kushanda kwekurapa kwemarara.
