I-Polydadmac, egama ligcwele i-polydimedldelldellium phermide, yi-ciolic polmer polymer esetyenziswe ngokubanzi kwicandelo lonyango lwamanzi. Ngenxa yoxinzelelo lwayo olukhethekileyo kunye nomhlaba ophakamileyo wamanzi, u-Soliday oPhezulu, iPolydadmac yindawo efanelekileyo yokususa i-turbidity, umbala kunye nezinye izinto zokungcola emanzini. Nangona kunjalo, kwizicelo ezisebenzayo, zihlala zisetyenziswa njengeiflocculantNgokudibeneyo nabanye abamameli ukuba baphathe amanzi amdaka.
Iimpawu kunye nendlela yesenzo se-polydadmadmadmadmad
I-Polydadmac ngokukhawuleza i-adfebs kwaye ixhase amasuntswana angabizi kakhulu coloidal amasuntswana kunye nezinyibilikisi ezinqunyanyisiweyo emanzini ngenxa yokuxinana okuphezulu. Indlela yayo yesenzo isekwe ikakhulu ekutsaleleni kwe-elektrostatic
I-Sydadmation ye-Polydadmac
Ukusetyenziswa kwelinye lamanyathelo kwinkqubo yokuhlasela. Ibhekisa kwinkqubo apho
"Iintyatyambo ezincinci ze-Alimam" zenziwa ngexesha lenkqubo yenkqubo ye-COARS enamachaphaza amakhulu e-adsorvor, ukungathathi cala kumbane, ibridmating kunye ne-blovrhor.
Kwicandelo lonyango lwamanzi, i-adsorption kunye nokungathathi cala kwezombane kuqhutywa njengokuhlanjwa, ngelixa ibridbang kunye ne-in-vansermang kunye ne-information icetyiswa njengeziqholo. Iichemicals ezihambelana nazo zibizwa ngokuba yi-dagulants kunye neendlela eziphilayo ngokwahlukeneyo.
Kuyakholelwa ngokubanzi ukuba i-polydadmac ineendlela ezintathu zesenzo: i-adsorption, ukungathathi cala kombane kunye nebhulorho. Ezona zimbini zokuqala zezona ziphambili. Yiyo loo nto i-polydadmac ihlelwe njengabameli. Nangona kunjalo, uninzi lwabantu luthathela ingqalelo ukudityaniswa kunye nokusetyenziswa njengenkqubo efanayo, ke ipolydadmac nayo yabizwa ngokuba yi-offcugunt.
Kwiinkqubo zonyango lwamanzi, i-polydadmac ikakhulu isetyenziswa njengeyintyatyambo ukuphucula umgangatho wamanzi. Ngokukodwa, iqela letyuwa le-Ammonium eliQineweyo lePolydadmac linokuvelisa umtsalane we-elektrostatic kunye namasuntswana anqunyanyisiweyo okanye amasuntswana asemanzini asemanzini, enze i-flucs yamasuntswana kwaye azinza. Ezi flocs zihlolwe ngexesha le-sedimetion okanye inkqubo yokuqhelisela ukucoca umgangatho wamanzi.
Izibonelelo zePolydadmadmadmadmac
Xa kuthelekiswa ne-placcungs yemveli (i-Alum, i-PAC, njl.), IPolydadmac inazo ezi zinto zilandelayo:
Goaldadmac inokukhawuleza ukususa ukungcola emanzini kunye nokuphucula umgangatho wamanzi.
Kulula ukusebenza: Ukusetyenziswa kwayo kuyinto elula, yongeza phantsi phantsi kweemeko ezifanelekileyo.
Ukuzinza: I-Polydadmac inozinzo oluhle kwaye ayiphumi lula njengePolyacyriade.
Isiphumo sobuchule esiqinileyo: Iqela letyuwa le-Ammoniium ye-Ammonium linika amandla e-pdmdaac enamandla, ngaloo ndlela ukuphatha ngeempawu ezahlukeneyo zamanzi;
Ukunganyangeki kwetyuwa, i-AID no-Alkali ilungele iimeko ezinzima zomgangatho wamanzi, kwaye isanengxaki yokusebenza kwezinto eziphantsi kwetyuwa, i-acidic okanye iimeko ze-acidic okanye i-abkaline
Ixabiso eliphantsi: I-Polydadmac inomgangatho ophezulu wokusebenza kunye nedosi ephantsi, enokunciphisa iindleko zonyango lwamanzi.
I-sludge esezantsi: i-polydadmac ivelisa i-sludgic encinci kunabantu abaziinqambisi kunye ne-placcunts kwaye bagcina iindleko zokungena emva.
I-Polydadmac Dosage kunye nezilumkiso
Xa usebenzisa iPolydadmac, iinkqubo zokusebenza kufuneka zilandelwe ngokungqongqo ukuqinisekisa iziphumo zonyango ezifanelekileyo kwaye kuthintele iziphumo ebezingalindelekanga. Ngokwesiqhelo, emva kongeza ii-placcunts ezinje nge-polloriaum chloride, i-polydadmac yongezwa ukuze ifezekise eyona nto iphambili. Ukongeza, idosi kufuneka ilungiswe ngokufanelekileyo ngokomgangatho wamanzi kunye neemfuno zonyango. Idosi efanelekileyo inokugqitywa ngovavanyo lwe-jar.
Konke kwinto enye,I-Polydadmadmacidlala indima ebalulekileyo kwicandelo lonyango lwamanzi. Ukuqonda okunzulu kweepropathi zayo kunye nezicelo kuya kunceda ukusebenzisa ngokupheleleyo le mveliso ukuphucula umgangatho wamanzi kunye nokukhusela indalo.
