Ho kopana ha mahlakorele ho phaphamala ha metsi ke motheo wa kalafo ya metsi ha ho batlwa metsi a hlwekileng. Tshebetso ena e matla e tataiswa ke thepa e phahameng ya aluminium sulfate, e fetolang metsi a silafetseng, a nang le mafome hore e be mohlodi o hlakileng wa kristale.
Aluminium sulfate, eo hangata e bitsoang alum, ke mohale ea sa rorisoang oa phekolo ea metsi. Ke letsoai le nang le foromo ea limolek'hule ea Al2(SO4)3. E qhibiliha ka metsing 'me e sebelisoa haholo-holo e le coagulant ho hloekiseng metsi a nooang le lifemeng tsa phekolo ea metsi a litšila, hammoho le ho etseng pampiri.
Alum e sebetsa joang letamong la ho sesa
Sulfate ea aluminium e hydrolyzes ho theha mefuta e rarahaneng e nang le tjhaja e matla ka metsing, mme di-particle matter ka hara tharollo di tjhaja hampe. Nakong ya dihora tse mmalwa, mofuta wa alum o hohela dikarolwana tse emisitsweng mme o fokotsa bongata ba tjhaja ya dikarolwana tse emisitsweng, ka hona, dikarolwana tsena di ka kopana ho ba floc e kgolo le e boima ho fihlela e teba butle tlase ho letamo. E sebetsa hantle ka mocheso o leka-lekaneng wa metsi a letamo le metsi wa bonyane di-degrees centigrade tse 70.
Mokhoa oa ho sebelisa alum e le sesebelisoa sa ho lokisaCoagulant ka matamong a ho sesa
1. Ho tlosa litšila tse ngata, ho hloekisa le ho ntsha borashe ho tlosa lithōle tse kholo.
2. Leka-lekanya pH ea letamo, alkalinity, thatafalo ea calcium, maemo a mahala a chlorine le asiti ea cyanuric ka mela ea rona ea liteko tsa letamo la ho sesa.
3. Tekanyo e tloaelehileng ea aluminium sulfate e sebelisoang e le flocculant matamong a ho sesa ke 20-50 mg/L. Kamora ho noa, letamo le lokela ho lula le potoloha lihora tse 2-8, ebe pompo e lokela ho tima 'me e tloheloe hore e eme lihora tse 12-24. Haeba phello e sa fihlelloe, pheta ts'ebetso.
4. Kenya valve e nang le masoba ka hare ho potoloho ea mali, sebelisa pompo lihora tse 2 ebe u hloekisa letamo.
5. Kwala pompo ka dihora tse 12-24 ho fihlela metsi a qhibilihile tlase ho letamo.
6. Beha valve ea orifice holim'a lintho tse litšila ebe u kenya alum e kenelletseng ka vacuum holim'a lintho tse litšila.
Aluminium sulfate e ka boela ea sebelisoa libakeng tse ling tse ngata, 'me re tla hlalosa ka bokhutšoanyane ka tlase.
Masela a dailoeng
E 'ngoe ea tšebeliso ea aluminium sulfate ke ho daea le ho hatisa lesela. Ha e qhibiliha ka bongata ba metsi ka pH e sa nke lehlakore kapa e nang le alkaline e nyane, motsoako ona o hlahisa slime e tsejoang e le aluminium hydroxide. Mucilage ena e thusa dae ho khomarela likhoele tsa lesela ka ho se qhibilihe ha dae ka metsi. Ka hona aluminium sulfate e sebetsa e le "fixative" ea dae, ho bolelang hore e tlamahane le sebopeho sa limolek'hule tsa dae le lesela e le hore dae e se ke ea matha ha lesela le le metsi.
Pampiri
Aluminium sulfate e sebediswa ho etsa pampiri. Aluminium sulfate e thusa ho lekanya pampiri. Mokgweng ona, e kopana le sesepa sa rosin ho fetola ho monyeha ha pampiri, mme ka hona e monya enke. Aluminium sulfate e hlahisa maemo a asiti, ha di-synthetic size agents di hlahisa pampiri e se nang asiti e sa boleng habonolo.
Likopo tsa Bongaka
Aluminium sulfate e na le ditšebeliso tse mmalwa tse sebetsang lefapheng la bongaka. E sebediswa haholoholo e le coagulant bakeng sa maqeba a manyane le maqeba le e le deodorant (ka lebaka la thepa ya yona ya ho lwantsha dikokwana-hloko). Motswako ona o boetse o monya le ho thibela di-antigen tsa protheine ka hara tharollo, mme ho potlaka ho hlahang ho ntlafatsa matla a ho itshireletsa mafung ka ho thusa ho lokolla di-antigen butle-butle ho tswa dibakeng tsa ho enta tse bopilweng sebakeng seo ho kentsweng ente ho sona. Ho phaella moo, ditharollo tse nang le 5% ho isa ho 10% di sebedisitswe e le ditshebediso tsa letlalo bakeng sa diso le ho thibela maro a nkgang hampe a tswang hodima matheba a mucous. Aluminium sulfate e teng dinthong tse sebediswang indastering ya meriana. Mohlala, e sebediswa ho lokiseng marothodi a tsebe a aluminium acetate.
