Unyango lwamanzi amdaka: Ukukhetha phakathi kwePolloluminum chloride kunye ne-aluminium Sulfate

Kwicandelo lonyango lwamanzi amdaka, zombini i-polloriam chloride (i-PAC) kunye ne-Alweuminium isetyenziswe ngokubanzi njengeI-Coaglants. Kukho umahluko kwisakhiwo sekhemikhali sala maxhasi zimbini, okukhokelela kwintsebenzo kunye nesicelo. Kwiminyaka yakutshanje, i-PAC ithathelwe ingqalelo ngokuthe ngcembe ngenxa yokusebenza kwawo kunye nesantya. Kweli nqaku, siza kuxubusha umahluko phakathi kwe-PAC kunye ne-Aluminium I-Sulfate kwiNkqubo yokuNikeza ukuze ikuncede wenze ukhetho olunolwazi ngakumbi.

Okokuqala, masifunde malunga ne-polloriam chloride (PAC). Njenge-Inorgan Polymer Cougulant, i-PAC inee-solity ezigqwesileyo kwaye inokukhawulezisa i-flocs. Idlala indima yokungathathi cala kunye nokuhamba kombane, kwaye isetyenziswa ngokudibeneyo ne-plocculant pam ukususa izinto ezingcolileyo kumanzi amdaka. Xa kuthelekiswa ne-Aluminium ye-Aluminium, i-PAC inamandla ombane kunye nomgangatho wamanzi ongcono emva kokucocwa. Ngeli xesha, iindleko zokucocwa kwamanzi ze-PAC yi-15% -30% isezantsi kune-aluminium sulfate. Ngokwe-alkalinity ye-alkalinity emanzini, i-PAC isebenzisa ukusetyenziswa kwezantsi kwaye inokunciphisa okanye kurhoxise inaliti yearhente yeAlkaline.

Okulandelayo yi-aluminium sulfate. Njenge-Cougurve yemveli, i-aluminium ye-adsorbs kwaye ivuselela ukungcola nge-Aluminium hydroxide eveliswe yi-hydrolysis. Ireyithi yayo yokuchithwa ihlwempuzekile, kodwa ilungele unyango lwamanzi amdaka nge-6.0-7.5. Xa kuthelekiswa ne-PAC, i-Aluminium ye-Aluminium inomthamo ophantsi wonyango kunye nomgangatho wamanzi acocekileyo, kwaye iindleko zokucocwa kwamanzi ziphezulu.

Ngokuphathelele kwimilinganiselo yokusebenza, i-PAC kunye ne-Aluminium Ine-Ilfate inezicelo ezahlukeneyo; I-PAC ilula ukuphatha kwaye ineefom zeflow ngokukhawuleza, ephucula ukusebenza ngonyango. I-Aluminium Sulfate, kwelinye icala, icotha i-hydrolyze kwaye inokuthatha ixesha elide ukuba ihlangane.

I-Aluminium SulfateUya kunciphisa i-pH kwaye i-alkanity yamanzi aphathwayo, ke isoda okanye i-lime iyafuneka ukuba ichaphazele isiphumo. Isisombululo se-PAC sisondele ekungathathi hlangothi kwaye akukho mfuneko yearhente engathathi hlangothi (isoda okanye i-lime).

Ngokubhekisele kugcino, i-PAC kunye ne-Aluminium I-Ilfate ihlala izinzile kwaye kulula ukuyigcina kunye nokuhambisa. Ngelixa i-PAC kufuneka itywinwe ukuthintela ukufunxa komswakama kunye nokuvezwa kwelanga.

Ukongeza, ukusuka kwinqanaba lokujonga i-corrosity, i-aluminium ye-Aluminium kulula ukuyisebenzisa kodwa ingakumbi. Xa ukhetha abameli, ifuthe elinokubakho kokubini kwizixhobo zonyango kufuneka lithathelwe ingqalelo ngokupheleleyo.

Isishwankathelo,I-polloluminum chloride. Lilonke, i-PAC ihamba kancinci iba ngummeli ophambili ngenxa yokusebenza okuphezulu, amanzi aphezulu okuhamba kwamanzi amdaka, kunye ne-chied firsied the the theite. Nangona kunjalo, i-allinum ye-aluminium isaziphethe iinyosi ezingenakufikelelwa phantsi kweemeko ezithile. Ke ngoko, xa ukhetha i-cougint, kwizinto ezinje ngemfuno, iziphumo zonyango kunye neendleko kufuneka ziqwalaselwe. Ukukhetha i-cougulant elungileyo kuya kunceda ukuphucula ukusebenza kakuhle konyango lwamanzi amdaka.
