Yiziphi ama-cationic flocculants ajwayelekile?

Ukwelashwa kwamanzi kuyisici esibalulekile sokuphathwa kwemvelo, ukuqinisekisa ukuthi amanzi aphephile ukusetshenziswa kanye nokusetshenziswa kwezimboni. Esinye sezici eziyinhloko kule nqubo ukusetshenziswa kwama-flocculant—amakhemikhali akhuthaza ukuqoqwa kwezinhlayiya ezilengisiwe zibe amaqoqo amakhulu, noma ama-floc, angase akhishwe kalula kakhudlwana emanzini. Phakathi kwezinhlobo ezihlukahlukene zama-flocculants, ama-cationic flocculants asebenza kahle kakhulu ngenxa yokushaja kwawo okuhle, okusebenzisana kakhulu nezinhlayiya ezikhokhiswa kabi ezivame ukutholakala emanzini angcolile. Lesi sihloko sihlola ama-cationic flocculants avame kakhulu asetshenziswa ekwelapheni amanzi kanye nezicelo zawo.

I-Cationic Polyacrylamides(CPAM)

I-Cationic Polyacrylamides, iphakathi kwama-flocculants asetshenziswa kakhulu embonini yokuhlanza amanzi. Kubasebenzisi abaningi, i-CPAM iyisinqumo sabo esingcono. Lawa ma-polymers aqukethe ama-subunits e-acrylamide, angalungiswa ukuze afake amaqembu asebenzayo we-cationic. Ukuguquguquka kwe-Cationic polyacrylamides kulele esisindweni samangqamuzana aguquguqukayo kanye nokuminyana kweshaji, okuwavumela ukuthi enziwe ngokwezifiso izinhlelo zokusebenza ezithile. Ama-C-PAM asebenza kahle kakhulu ekwelapheni amanzi angcolile ezimbonini kanye nokususa amanzi ngodaka ngenxa yokusebenza kahle kwawo okuphakeme kanye nezidingo zomthamo ophansi uma kuqhathaniswa.

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

I-PolyDADMAC iyi-cationic flocculant esetshenziswa kabanzi eyaziwa ngokuxineka kwayo okuphezulu nokusebenza kahle ezinqubweni zokwelashwa kwamanzi. Le polymer isebenza kahle kakhulu ezinqubweni ze-coagulation kanye ne-flocculation, ikwenze kube ukukhetha okudumile ukwelapha amanzi okuphuza, amanzi angcolile, nokungcola kwezimboni. I-PolyDADMAC isebenza kahle ngokuhlangana namanye ama-flocculants nama-coagulant, ithuthukisa inqubo yokwelapha iyonke ngokunikeza indlela eqinile yokuhlanganisa izinhlayiyana nokususwa.

Ama-Polyamines(PA)

I-Polyamines ingesinye isigaba se-cationic flocculants evame ukusetshenziswa ekwelashweni kwamanzi. Lezi zinhlanganisela, ezihlanganisa i-poly(dimethylamine-co-epichlorohydrin) kanye nezakhiwo ezifanayo, zibonisa ukuminyana kweshaje ye-cationic eqinile, okuzenza ziphumelele kakhulu ekunciphiseni izinhlayiya ezishajwa kabi. Ama-Polyamine awusizo ikakhulukazi ekucaciseni amanzi aluhlaza, ukususwa kwezinto eziphilayo, kanye nokwelapha ukungcola okuhlukahlukene kwezimboni. Ikhono labo lokwenza ama-flocs aminyene liholela ezikhathini zokuzinza ngokushesha kanye nokucaca okuthuthukisiwe kwamanzi ahlanzekile.

Izicelo kanye Nezinzuzo

Ama-Cationic flocculants adlala indima ebalulekile ezinhlobonhlobo zezicelo zokuhlanza amanzi, kusukela ekuhlanzeni amanzi angcolile kamasipala kanye nokuhlanza amanzi okuphuza kuya ekulawuleni ukungcola kwezimboni. Inzuzo yabo eyinhloko isemandleni abo okunciphisa ngokuphumelelayo izinhlayiya ezikhokhiswa kabi, okuholela ekwakhekeni kwe-floc ngokushesha nangempumelelo. Lokhu kuphumela ekucaceni okuthuthukisiwe, ukuncipha kokuthuthumela, kanye nekhwalithi yamanzi ethuthukisiwe. Ukwengeza, ama-cationic flocculants avame ukusetshenziswa ngokuhlanganiswa namanye amakhemikhali okwelapha, njengama-coagulants, ukuze kuthuthukiswe inqubo yokwelapha futhi kuzuzwe amazinga afiswayo ekhwalithi yamanzi.

Ukusetshenziswa kwama-cationic flocculants kuyingxenye yezinqubo zesimanje zokwelashwa kwamanzi, okunikeza izixazululo ezisebenza kahle nezithembekile zokuhlanganisa nokususwa kwezinhlayiyana. I-Polyacrylamides, i-polyamines, i-PolyDADMAC imelela amanye ama-cationic flocculants ajwayelekile futhi asebenzayo atholakalayo namuhla. Ukuguquguquka kwazo, ukusebenza kahle, nokuvumelana nezimo kuzenza zibe amathuluzi abalulekile ekuqinisekiseni ukutholakala kwamanzi ahlanzekile naphephile ukuze asetshenziswe ngezindlela ezihlukahlukene.

Yebo, ukukhetha kwe-flocculant nakho kuncike emikhubeni yokusebenzisa yomsebenzisi, ukwakheka kwezinto ezibonakalayo, indawo ezungezile, njll. Umhlahlandlela wokusetshenziswa komkhiqizo kufanele ulandelwe.
