Aluminium chlorohydrate (ACH) nepolyaluminum chloride (PAC) zvinoita semakemikari maviri akasiyana anoshandiswa seflocculants mukurapa nemvuraKutaura zvazviri, ACH ndiyo inonyanya kuumbwa mumhuri yePAC, ichipa huwandu hwepamusoro hwealumina uye hunogona kuwanikwa mumhando dzakasimba kana mafomu emhinduro dzakagadzikana. Ava vaviri vane mashandiro akasiyana zvishoma, asi nzvimbo dzavanoshandisa dzakasiyana zvikuru. Chinyorwa chino chichakupa kunzwisisa kwakadzama kweACH nePAC kuitira kuti ugone kusarudza chigadzirwa chakakodzera.
Polyaluminum chloride (PAC) ipolymer ine mamorekuru akawanda ine fomura yemakemikari [Al2(OH)nCl6-n]m. Nekuda kwehunhu hwayo hwemakemikari hwakasiyana, ine mashandisirwo akasiyana-siyana muminda yakasiyana-siyana. Polyaluminum chloride (PAC) inoita basa rakakosha mukurapa mvura, ichibvisa zvinobudirira zvinhu zvakasimba zvakamiswa, zvinhu zvecolloidal, uye zvinhu zvisinganyunguduke kuburikidza nemaitiro ekuomesesa. Nekubvisa zvidimbu, PAC inokurudzira kuungana, zvichiita kuti zvibviswe mumvura. PAC, inowanzoshandiswa pamwe chete nemamwe makemikari akaita sePAM, inowedzera kunaka kwemvura, inoderedza kusviba, uye inosangana nezvinodiwa zveindasitiri.
Muchikamu chekugadzira mapepa, PAC inoshanda senzira yekuderedza kusvibiswa kwemvura uye inokonzeresa kusvibiswa kwetsvina uye inovandudza kukura kwetsvina uye saizi yerosin-neutral. Inowedzera kukura kwemasero, ichidzivirira kusvibiswa kwemachira nehurongwa hwezvinhu.
Mashandisirwo ePAC anoshandawo muindasitiri yemigodhi, zvichibatsira mukusuka matombo esimbi uye kupatsanura zvicherwa. Inoparadzanisa mvura kubva kugangue, zvichiita kuti ishandiswezve, uye inobvisa mvura mumarara.
Mukubvisa nekuchenesa peturu, PAC inobvisa tsvina, zvinhu zvisinganyungudike, uye simbi kubva mumvura yakasviba. Inobvisa madonhwe emafuta, ichidzikamisa matsime emvura uye inodzivirira kukuvara kwekuumbwa kwemafuta panguva yekuchera mafuta.
Kudhinda nekudhaya machira kunobatsirwa nekugona kwePAC kurapa mvura yakasviba yakawanda uye ine zvinhu zvakawanda zvinosvibisa zvisikwa. PAC inokurudzira kugadzikana kwakasimba uye nekukurumidza kwemaruva ealum, zvichiita kuti pave nemigumisiro inoshamisa pakurapa.
ACH, Aluminium Chlorohydrate, ine fomura yemorekuru Al2(OH)5Cl·2H2O, ipolymer compound isina kugadzirwa ine alkali yakakwira zvichienzaniswa nepolyaluminum chloride uye inoteverwa nealuminium hydroxide chete. Inopfuura nepakati pemabridge polymerization kuburikidza nemapoka ehydroxyl, zvichikonzera kuti molekyuru ive nenhamba yepamusoro yemapoka ehydroxyl.
Inowanikwa mumhando dzekuchenesa mvura uye dzemakemikari ezuva nezuva (giredhi rezvekushongedza), ACH inouya mumhando dzeupfu (yakasimba) uye yemvura (mhinduro), ine yakasimba iri upfu chena uye mhinduro iri mvura isina ruvara inoonekera.
Zvinhu zvisinganyunguduki uye huwandu hweFe hwakaderera, saka zvinogona kushandiswa muminda yemakemikari yezuva nezuva.
ACH inoshandisa nzira dzakasiyana siyana. Inoshanda sezvinhu zvemishonga nezvizoro zvemhando yepamusoro, kunyanya sechinhu chikuru chinodzivirira kubuda kwemhepo chinozivikanwa nekushanda kwayo, kusakurumidza kushatirwa, uye kuchengetedzeka. Pamusoro pezvo, ACH inodhura uye saka haiwanzo shandiswa semushonga wemvura inoyerera mumvura yekunwa uye mushonga wemvura yakasviba mumaindasitiri. ACH inoratidzawo kunyorova kunoshanda pamusoro pe pH spectrum yakafara kupfuura simbi yemazuva ano uye polyaluminum chloride dzine low-basin.
