Yeyiphi imichiza esetyenziselwa i-Flocculation?

I-Flocculationyinkqubo esetyenziswa kumashishini ahlukeneyo, ngakumbi kunyango lwamanzi kunye nokucocwa kwamanzi amdaka, ukudibanisa amasuntswana amisiweyo kunye ne-colloids ibe ngamasuntswana efloc amakhulu. Oku kuququzelela ukususwa kwazo ngokusebenzisa intlenga okanye ukuhluzwa. Ii-agent zekhemikhali ezisetyenziselwa ukuhluma zaziwa ngokuba zii-flocculants. Enye yezona flocculants zixhaphakileyo kwaye zisetyenziswa ngokubanzi yi-polyacrylamide.

Polyacrylamideyipolymer eyenziwe kwi-acrylamide monomers. Ikhona kwiifom ezahlukeneyo, kubandakanywa i-anionic, i-cationic, kunye ne-non-ionic, nganye inezicelo ezithile. Ukukhethwa kohlobo lwepolyacrylamide kuxhomekeke kubume bamasuntswana emanzini kunye nesiphumo esinqwenelekayo senkqubo ye-flocculation.

I-Anionic polyacrylamide ihlawuliswa kakubi kwaye isetyenziswa rhoqo kunyango lwamanzi amdaka aqukethe amasuntswana ahlawulweyo afana nodongwe kunye nezinto eziphilayo. I-Cationic polyacrylamide, kwelinye icala, ihlawuliswa kakuhle kwaye iyasebenza ekuphatheni amanzi ngamasuntswana ahlawuliswa kakubi njengezinto eziqinileyo kunye nodaka. I-polyacrylamide engekho i-ionic ayinayo intlawulo kwaye ifanelekile kwi-flocculation yoluhlu olubanzi lwamasuntswana.

Iiflocculants zePolyacrylamide zisebenza ngokubhengeza kumphezulu wamasuntswana, zenza iibhulorho phakathi kwazo, kwaye zenze iiaggregates ezinkulu. Iiflokhi ezibangelwayo kulula ukuzinza okanye ukuhluza ngaphandle kwamanzi. I-Polyacrylamide ikhethwa ngenxa yobunzima bayo obuphezulu bemolekyuli, ephucula ubuchule bayo bokuhamba kunye nokuhamba.

Ngaphandle kwe-polyacrylamide, ezinye iikhemikhali zikwasetyenziselwa i-flocculation, kuxhomekeke kwiimfuno ezithile zenkqubo yonyango. flocculants Inorganic, ezifanaI-aluminium Sulfate(i-alum) kunye ne-ferric chloride, zidla ngokusetyenziswa kunyango lwamanzi. Ezi khemikhali zenza i-metal hydroxide flocs xa zongezwa emanzini, zinceda ekukhutshweni kweengqungquthela ezimisiwe.

I-alum, ngokukodwa, isetyenziswe ngokubanzi ukucaciswa kwamanzi iminyaka emininzi. Xa ifakwe emanzini, i-alum ingena kwi-hydrolysis, yenze i-aluminium hydroxide flocs ebamba ukungcola. Iiflocs ziyakwazi ukuhlala, kwaye amanzi acacisiweyo anokwahlulwa kwintlenga.

I-Flocculation yinyathelo elibalulekileyo kwiinkqubo zokunyanga amanzi, ukuqinisekisa ukukhutshwa kokungcola kunye nokuvelisa amanzi acocekileyo. Ukukhethwa kwe-flocculant kuxhomekeke kwizinto ezifana neempawu zamanzi eziza kunyangwa, uhlobo lwamaqhekeza akhoyo, kunye nesiphumo sonyango esifunwayo. I-Polyacrylamide kunye nezinye iiflocculants zidlala indima ebalulekileyo ekwandiseni ukusebenza kakuhle kwamanzi kunye neenkqubo zokucocwa kwamanzi amdaka, negalelo ekuboneleleni ngamanzi akhuselekileyo kunye nokusela ngeenjongo ezahlukeneyo.
