Flocculation hamwe na flucculation

GUKURIKIRA
Mu rwego rwa chimie, flocculation ninzira itandukanya uduce duto twa colloidal duva mu mvura igwa mu bwoko bwa flocculent cyangwa flake bivuye mu guhagarikwa haba ku bushake cyangwa hiyongereyeho ibisobanuro. Ubu buryo butandukanye n’imvura kubera ko colloid ihagarikwa gusa mumazi nkikwirakwizwa rihamye mbere ya flocculation kandi ntabwo iseswa mubisubizo.
Coagulation na flocculation ninzira zingenzi mugutunganya amazi. Igikorwa cya coagulation nuguhungabanya no kwegeranya uduce duto hakoreshejwe imikoreshereze yimiti hagati ya coagulant na colloid, hanyuma igahindura kandi ikagusha ibice bitajegajega mukuyihuza na flocculation.

BISOBANURO
Nk’uko IUPAC ibivuga, flocculation ni “inzira yo guhuza no gufatana hamwe aho uduce duto two gutatanya tugize ihuriro rinini”.
Ahanini, flocculation ninzira yo kongeramo flocculant kugirango ihungabanye uduce duto twashizwemo. Mugihe kimwe, flocculation nubuhanga bwo kuvanga butera agglomeration kandi bigira uruhare mugutuza ibice. Coagulant isanzwe ni Al2 (SO4) 3 • 14H2O.

Umwanya wo gusaba

IKORANABUHANGA RY'AMAZI
Flocculation n'imvura bikoreshwa cyane mugusukura amazi yo kunywa no gutunganya imyanda, amazi yimvura n’amazi mabi y’inganda. Uburyo busanzwe bwo kuvura burimo ibinezeza, coagulation, flocculation, imvura, kuyungurura uduce no kwanduza.
CHEMISTRY YITONDE
Muri chimie ya colloidal, flocculation ninzira itondekanya uduce duto duto. Floc irashobora noneho kureremba hejuru yamazi (opalescent), gutura munsi yamazi (precipitate) cyangwa kuyungurura byoroshye mumazi. Imyitwarire ya flocculation yubutaka colloid ifitanye isano rya hafi nubwiza bwamazi meza. Ikwirakwizwa ryinshi ryubutaka bwa colloid ntabwo ritera gusa guhungabana kw’amazi akikije, ahubwo binatera eutrophasiya kubera kwinjiza intungamubiri mu nzuzi, ibiyaga ndetse no mu mazi.

CHIMISTRY YUMUBIRI
Kuri emulisiyo, flocculation isobanura kwegeranya ibitonyanga bitatanye kugirango ibitonyanga byabantu bitatakaza imitungo yabo. Rero, flocculation nintambwe yambere (droplet coalescence no gutandukanya icyiciro cya nyuma) biganisha ku gusaza kwa emulsiyo. Flocculants ikoreshwa mugutunganya amabuye y'agaciro, ariko irashobora no gukoreshwa mugushushanya ibintu bifatika byibiribwa nibiyobyabwenge.

SHAKA

Guhindura flokculasiyo bihabanye rwose na flocculation kandi rimwe na rimwe byitwa gelling. Sodium silikatike (Na2SiO3) ni urugero rusanzwe. Ibice bya colloidal mubisanzwe bikwirakwizwa murwego rwo hejuru rwa pH, usibye imbaraga nke za ionic zumuti hamwe niganjemo ibyuma bya monovalent. Inyongeramusaruro zibuza colloid gukora flocculent yitwa antiflocculants. Kuri flocculation ihindagurika binyuze kuri bariyeri ya electrostatike, ingaruka za flocculant zinyuranye zishobora gupimwa nubushobozi bwa zeta. Nk’uko inkoranyamagambo ya Encyclopedia ya Polymers ibivuga, antiflocculation ni “leta cyangwa imiterere yo gukwirakwiza ikintu gikomeye mu mazi aho buri kintu gikomeye kiguma cyigenga kandi kidafitanye isano n’abaturanyi (cyane nka emulifiseri). Ihagarikwa ridahindagurika rifite zeru cyangwa umusaruro muke cyane ".
Guhindura flocculation birashobora kuba ikibazo mubihingwa bitunganya imyanda kuko akenshi biganisha kumyanda ikemura ibibazo no kwangirika kwamazi meza.
