Amagama angundoqo kwinqaku: I-Aluminium Sulfate, iFerrous Sulfate, iPolyaluminum Chloride (PAC), iPolyacrylamide (PAM)
I-aluminium sulfate yi-compound eqhelekileyo ye-inorganic enefomyula yekhemikhali i-Al₂(SO₄)₃, ubunzima be-molecular obuyi-342.15, kunye nembonakalo emhlophe yekristale. Njenge-arhente ebalulekileyo yekhemikhali kwicandelo lokunyanga amanzi, umsebenzi wayo ophambili kukuvelisa amasuntswana e-colloidal ngokusebenzisa ii-hydrolysis reactions; la masuntswana afunxa kwaye anciphise izinto eziqinileyo ezixhonyiweyo, ii-colloids, kunye nokungcola okuthile okunyibilikisiweyo okukhoyo emanzini, ngaloo ndlela kufezekiswa ukucocwa kwamanzi. Iimeko zokusetyenziswa kwayo ziquka iinkalo ezahlukeneyo, kubandakanya unyango lwamanzi okusela, unyango lwamanzi amdaka kwimizi-mveliso, ukulungiswa kwee-arhente zokulinganisa i-rosin kwishishini lokwenza iphepha, kunye nokususwa kombala kwi-petroleum.
I. Imigaqo yoBugcisa kunye nemisebenzi ephambili:
Xa i-aluminium sulfate inyibilika emanzini, ii-aluminium ion (Al³⁺) zibophana neemolekyuli zamanzi ukuze zenze ii-aluminium ion ezimanzi, ezithi emva koko zidlule kwi-hydrolysis eyongezelelweyo ukuze zenze ii-aluminium hydroxide colloids. Imiphezulu yezi colloids inetshaja entle, evumela ukuba zinciphise iitshaja ezimbi kumasuntswana axhonyiweyo emanzini. Oku kuthomalalisa kuphazamisa ukuzinza kwamasuntswana, kukhuthaza ukuhlangana kwawo abe zii-flocs ezinkulu (ii-clumps), ezithi ekugqibeleni zahlulwe nge-sedimentation okanye i-filtration. Le nkqubo yonke yaziwa ngokuba yi-"coagulation-sedimentation" kwaye yenza inyathelo elibalulekileyo ekunyangweni kwamanzi. Ngaphezu koko, i-aluminium sulfate inokusabela kwii-ion ezithile zesinyithi esinzima ezikhoyo emanzini (ezifana ne-iron kunye ne-manganese) ukuze zenze ii-precipitates ezinganyibilikiyo, ngaloo ndlela zincede ekususweni kwezinto ezingcolisayo ezinyibilikisiweyo.
I-Aojin Chemical inikezela ngeendidi zeemveliso zonyango lwamanzi ezithengiswayo, kuquka i-aluminium sulfate, i-ferrous sulfate,I-Polyaluminum Chloride (PAC)kunye I-Polyacrylamide (i-PAM)Abathengi bayakhuthazwa ukuba bakhethe iimveliso ngokweemfuno zabo ezithile. Siyamkela nabani na ofuna iimveliso zokucoca amanzi ukuba aqhagamshelane ne-Aojin Chemical!
II. Imeko zokusetyenziswa kunye nezinto eziqwalaselwayo ekusebenzeni:
Xa kucocwa amanzi okusela, i-aluminium sulfate idla ngokusetyenziswa kunye nezixhobo ze-coagulant—ezifana ne-activated carbon okanye i-polyacrylamide—ukususa ngempumelelo i-turbidity, i-algae, kunye nezinto eziphilayo. Xa kucocwa amanzi amdaka kwimizi-mveliso, umlinganiselo we-aluminium sulfate kufuneka uhlengahlengiswe ngokusekelwe kwixabiso le-pH yamanzi: phantsi kweemeko ze-asidi, i-hydrolysis yee-ion ze-aluminium iyaqhubeka ngokufanelekileyo; nangona kunjalo, umlinganiselo ogqithisileyo unokubangela amanqanaba e-aluminium aseleyo kwi-liff ephathwayo edlula imida yomthetho. Ngokwahlukileyo koko, kwiindawo ze-alkaline, kuyimfuneko ukongeza ii-arhente zokulungisa i-pH (ezifana nelayimu) ukuze kuphuculwe ukusebenza kwe-flocculation. Kwishishini lokwenza iphepha, i-aluminium sulfate isebenza njengearhente yokulinganisa ubungakanani be-rosin; isabela kunye nee-rosin acids ukwenza isepha ze-aluminium ezinganyibilikiyo, ngaloo ndlela iphucula ukumelana namanzi ephepha. Kwicandelo lokutshintsha umbala kwe-petroleum, iipropati zokufunxa zekhompawundi zisetyenziselwa ukususa iintsini kunye ne-asphaltenes kwiimveliso zeoyile. III. Iingenelo zobugcisa kunye nokusebenza okusebenzayo:
Xa kuthelekiswa nezinye ii-flocculants (ezifana neetyuwa zesinyithi), i-aluminium sulfate ineempawu ezilandelayo: Okokuqala, i-colloidal aluminium hydroxide eveliswa ngexesha le-hydrolysis inobukhulu obufanayo be-particle kunye nokusebenza kakuhle kwe-flocculation, ngaloo ndlela inciphisa idosi efunekayo ye-chemical agent. Okwesibini, isebenza kuluhlu olubanzi lwe-pH (5.5–8.5), isusa isidingo sokulungiswa okukhulu kwe-acidity okanye i-alkalinity yamanzi. Okwesithathu, ii-ion ze-aluminium ezisele zingasuswa ngakumbi ngeenkqubo zonyango ezilandelayo (ezifana nokuhluzwa kwesanti okanye ukutsalwa kwekhabhoni esebenzayo), ngaloo ndlela kunciphisa umngcipheko wongcoliseko lwesibini. Idatha yovavanyo ibonisa ukuba xa kunyangwa amanzi omlambo ane-turbidity ephezulu, idosi ye-aluminium sulfate engama-30–50 mg/L inokufikelela kwizinga lokususwa kwe-turbidity elingaphezulu kwe-90%, ukuqinisekisa ukuba ukungcola okucociweyo kuyahlangabezana nemigangatho yococeko yamanzi okusela asekhaya.
IV. Izikhokelo zoKhuseleko kunye noGcino:
Kubalulekile ukuphepha ukugcina kunye neziseko eziqinileyo okanye ii-oxidizing agents ezinamandla ukuthintela iimpembelelo ezingaphandle kobushushu. Indawo yokugcina kufuneka igcinwe yomile kwaye igcinwe kubushushu obungaphantsi kwama-50°C ukuthintela imveliso ekufunxeni umswakama kunye nokugquma. Ngexesha lokuphatha, kufuneka unxibe iiglavu zokukhusela kunye neeglasi zokhuseleko ukuthintela ukuphefumla uthuli okanye ukudibana nolusu. Kwimeko yokudibana ngengozi namehlo, hlambulula ngoko nangoko ngamanzi acocekileyo amaninzi kwaye ufune unyango. Ngexesha lokuthuthwa, kufuneka kuthathwe amanyathelo okukhusela imveliso kumswakama kunye nomonakalo womzimba, ukuqinisekisa ukuthembeka kwephakheji.
