Cov tshuaj tseem ceeb siv rau coagulation yog aluminium sulphate ( alum ), polyaluminium chloride (tseem hu ua PAC lossis kua alum ), alum potash, thiab hlau ntsev (ferric sulfate los yog ferric chloride ).
Ua li no, tshuaj coagulation yog dab tsi?
Kev kho cov dej hauv dej…a tshuaj txheej txheem hu ua coagulation . Tshuaj (coagulants) tau ntxiv rau hauv dej kom coj cov khoom tsis sib haum xeeb ua ke rau hauv qhov loj dua, hnyav dua ntawm cov khoom hu ua floc. Aluminium sulfate (alum) yog feem ntau coagulant siv rau purification dej.
Kuj Paub, ob yam tshuaj twg yog siv los ua dej coagulants? Tshuaj coagulants siv hauv kev kho dej
- Aluminium Sulfate (Alum) - Ib qho ntawm cov tshuaj kho dej feem ntau siv hauv ntiaj teb.
- Aluminium Chloride - Ib qho kev xaiv thib ob rau Alum vim nws kim dua, muaj kev phom sij thiab corrosive.
- Polyaluminium Chloride (PAC) & Aluminium Chlorohydrate (ACH)
Tsis tas li ntawd, cov tshuaj twg siv rau flocculation?
Cov aluminium coagulants suav nrog aluminium sulfate, aluminium chloride thiab sodium aluminate. Cov hlau coagulants muaj xws li ferric sulfate, ferrous sulfate, ferric chloride thiab ferric chloride sulfate. Lwm yam tshuaj siv ua coagulants suav nrog hydrated txiv qaub thiab magnesium carbonate.
Dab tsi yog coagulant ua los ntawm?
Tshuaj coagulants muaj xws li txhuas sulfate (alum), ferric chloride, txiv qaub, thiab polymers. Tsawg molecular hnyav cationic polymers thiab inorganic txhuas thiab hlau ntsev (xws li alum thiab ferric sulphate) yog cov feem ntau siv zoo them nqi coagulants.

Hom tshuaj twg pom nyob rau hauv cov khoom ntawm cov tshuaj tiv thaiv decomposition?
Cov tshuaj tiv thaiv decomposition tshwm sim thaum ib qho reactant tawg mus rau hauv ob lossis ntau yam khoom. Qhov no tuaj yeem sawv cev los ntawm kev sib npaug dav: AB → A + B. Cov piv txwv ntawm cov tshuaj tiv thaiv decomposition muaj xws li kev tawg ntawm hydrogen peroxide rau dej thiab oxygen, thiab kev tawg ntawm cov dej mus rau hydrogen thiab oxygen
Cov tshuaj twg yog siv rau hauv cov khoom kub thiab txias?
Instant Kub thiab Cold Packs Raws li cov ntsev disassociates, tshav kub yog tso tawm nyob rau hauv ib qho exothermic cov tshuaj tiv thaiv los yog absorbed nyob rau hauv ib tug endothermic cov tshuaj tiv thaiv. Cov khoom lag luam tam sim no feem ntau siv ammonium nitrate lossis urea ua lawv cov ntsev tivthaiv; Cov pob kub feem ntau siv magnesium sulfate lossis calcium chloride
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Cov khoom twg yog cov piv txwv ntawm cov khoom siv tshuaj xyuas txhua yam uas siv?
Piv txwv ntawm cov khoom siv tshuaj muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion. Hlau, piv txwv li, ua ke nrog oxygen nyob rau hauv lub xub ntiag ntawm dej los ua xeb; chromium tsis oxidize (Daim duab 2)
Vim li cas thiaj siv cov tshuaj tua kab mob hauv cov tshuaj distillation?
Lub hom phiaj ntawm kev sib tsoo granules Saib Lawv nres, uas qhov tshwm sim tam sim ntawd ntawm vapor npuas nyob rau hauv cov kua kub ua rau upwards splashing. Theanti-bumping granules ua raws li lub hom phiaj rau theformation ntawm vapor cia du boiling
