Yiziphi izinhlobo ezivamile ze-cationic flocculants?

Ukwelashwa kwamanzi kuyisici esibalulekile sokuphathwa kwemvelo, okuqinisekisa ukuthi amanzi aphephile ukusetshenziswa kanye nokusetshenziswa kwezimboni. Esinye sezici ezibalulekile kule nqubo ukusetshenziswa kwama-flocculant—amakhemikhali akhuthaza ukuhlanganiswa kwezinhlayiya ezilengisiwe zibe amaqoqo amakhulu, noma ama-floc, angasuswa kalula emanzini. Phakathi kwezinhlobo ezahlukene zama-flocculant, ama-cationic flocculant asebenza kahle kakhulu ngenxa yokushaja kwawo okuhle, okuthintana kakhulu nezinhlayiya ezishajwe kabi ezivame ukutholakala emanzini angcolile. Lesi sihloko sihlola ama-cationic flocculant avame ukusetshenziswa ekwelapheni amanzi kanye nokusetshenziswa kwawo.

Ama-Polyacrylamides e-Cationic(CPAM)

Ama-Cationic Polyacrylamides, aphakathi kwama-flocculant asetshenziswa kakhulu embonini yokwelapha amanzi. Kubasebenzisi abaningi, i-CPAM iyindlela engcono kakhulu abakhetha ngayo. Lawa ma-polymer aqukethe ama-subunit e-acrylamide, angenziwa ngendlela yokuthi afake amaqembu asebenzayo e-cationic. Ukuguquguquka kwama-Cationic polyacrylamides kusesisindo sawo sama-molecule esilungisekayo kanye nobuningi bamashaja, okuvumela ukuthi enziwe ngokwezifiso zezinhlelo ezithile. Ama-C-PAM asebenza kahle kakhulu ekwelapheni amanzi angcolile ezimbonini kanye nokususwa kwamanzi ngenxa yokusebenza kwawo okuphezulu kwe-flocculation kanye nezidingo zomthamo eziphansi.

I-Poly (i-diallyldimethylammonium chloride) (I-PolyDADMAC)

I-PolyDADMAC iyi-flocculant ye-cationic esetshenziswa kabanzi eyaziwa ngokushaja kwayo okuphezulu kanye nokusebenza kahle kwezinqubo zokwelashwa kwamanzi. Le polymer isebenza kahle kakhulu ezinqubweni zokubopha kanye nokubopha, okwenza kube ukukhetha okuthandwayo kokwelapha amanzi okuphuza, amanzi angcolile, kanye nokungcola kwezimboni. I-PolyDADMAC isebenza kahle ngokubambisana nezinye izinto zokubopha kanye nezimbotshana, ithuthukisa inqubo yokwelapha iyonke ngokunikeza indlela eqinile yokuhlanganisa nokususa izinhlayiya.

Ama-Polyamine(PA)

Ama-polyamines angenye indlela yama-flocculant e-cationic asetshenziswa kakhulu ekwelapheni amanzi. Lawa ma-compound, afaka phakathi i-poly (dimethylamine-co-epichlorohydrin) kanye nezakhiwo ezifanayo, abonisa ukuminyana okukhulu kwe-cationic charge, okwenza asebenze kahle kakhulu ekuqedeni izinhlayiya ezishajelwe kabi. Ama-polyamines awusizo kakhulu ekucaciseni amanzi angavuthiwe, ekususeni izinto eziphilayo, kanye nasekuphatheni ukungcola okuhlukahlukene kwezimboni. Amandla awo okwakha ama-floc aminyene aholela ezikhathini zokuzinza okusheshayo kanye nokucaca okuthuthukisiwe kwamanzi aphathwe.

Izicelo kanye nezinzuzo

Ama-flocculant e-cationic adlala indima ebalulekile ezinhlobonhlobo zezicelo zokwelashwa kwamanzi, kusukela emanzini angcolile kamasipala kanye nokuhlanzwa kwamanzi okuphuza kuya ekuphathweni kokungcola kwezimboni. Inzuzo yawo eyinhloko isekhonweni lawo lokuqeda ngempumelelo izinhlayiya ezishajelwe kabi, okuholela ekwakhekeni kwe-floc okusheshayo nokusebenzayo. Lokhu kuphumela ekucaceni okuthuthukisiwe, ukwehla kokungcoliswa kwamanzi, kanye nekhwalithi yamanzi ethuthukisiwe. Ngaphezu kwalokho, ama-flocculant e-cationic avame ukusetshenziswa ngokuhlanganiswa namanye amakhemikhali okwelapha, njenge-coagulants, ukuze kuthuthukiswe inqubo yokwelapha futhi kufezwe amazinga ekhwalithi yamanzi afunwayo.

Ukusetshenziswa kwama-flocculant e-cationic kubalulekile ezinqubweni zanamuhla zokwelashwa kwamanzi, okunikeza izixazululo ezisebenzayo nezithembekile zokuhlanganisa nokususa izinhlayiya. Ama-Polyacrylamides, ama-polyamine, ama-PolyDAMAC amelela amanye ama-flocculant e-cationic avame kakhulu futhi asebenzayo atholakala namuhla. Ukuguquguquka kwawo, ukusebenza kahle, kanye nokuzivumelanisa nezimo kwenza kube amathuluzi abalulekile ekuqinisekiseni ukutholakala kwamanzi ahlanzekile naphephile okusetshenziswa okuhlukahlukene.

Vele, ukukhetha i-flocculant kuncike emikhubeni yokusebenzisa yomsebenzisi, ukwakheka kwezinto, indawo ezungezile, njll. Umhlahlandlela wokusebenzisa umkhiqizo kufanele ulandelwe.
