Chii chinoitika kana aluminium sulphate ikasangana nemvura?

Aluminium sulfate, kemikari inomiririrwa seAl2 (SO4) 3, ichena crystalline yakasimba iyo inowanzoshandiswa mukugadzirisa mvura.Kana aruminiyamu sulfate ikasangana nemvura, inopinda muhydrolysis, kemikari inoitika umo mamorekuru emvura anotsemura komboni kuita maion ayo.Kuita uku kunobata basa rakakosha mumashandisirwo akasiyana siyana, kunyanya mukuchenesa mvura.

Chigadzirwa chekutanga chekuita uku ialuminium hydroxyl yakaoma.Iyi yakaoma yakakosha mukurapa kwemvura, sezvo inobatsira mukubvisa tsvina kubva mumvura.Aluminium hydroxyl complex ine high charge density, uye kana ikaumbwa, inoita zvekuteya nekubatanidza zvimedu zvakamiswa, zvakaita sevhu, silt, uye organic matter.Nekuda kweizvozvo, tutsvina tudiki twunokura uye hunorema, zvichiita kuti zvive nyore kuti dzigare kunze kwemvura.

Iyo sulfuric acid inogadzirwa mukuita inoramba iri mumhinduro uye inobatsira kune yakazara acidity yehurongwa.Iyo acidity inogona kugadziriswa sezvinodiwa, zvichienderana nezvinodiwa chaizvo zvekugadzirisa mvura.Kudzora iyo pH kwakakosha pakugadzirisa kushanda kweiyo coagulation uye flocculation maitiro.Inoderedzawo alkalinity yemvura.Kana iyo alkalinity yemvura yedziva pachayo yakaderera, ipapo NaHCO3 inoda kuwedzerwa kuwedzera alkalinity yemvura.

Kuita pakati pealuminium sulfate nemvura kunowanzo shandiswa mukubatanidza uye flocculation nhanho dzemvura yekurapa zvidyarwa.Coagulation inosanganisira kudzikisira kwezvimedu zvakamiswa, nepo flocculation inosimudzira kuunganidzwa kwezvimedu izvi muhombe, nyore kugadzika flocs.Maitiro ese ari maviri akakosha pakubviswa kwetsvina uye kujekeswa kwemvura.

Zvakakosha kuziva kuti kushandiswa kwealuminiyamu sulfate mukurapwa kwemvura kwakasimudza kushushikana kwezvakatipoteredza nekuda kwekugona kuunganidzwa kwealuminium muzvisikwa zvemumvura.Kuti uderedze zvinonetsa izvi, chaiyo dosing uye yekutarisa kwakakosha kuti ive nechokwadi chekuti maaruminiyamu ekumisikidza mumvura yakacheneswa anosangana nemirairo.

Mukupedzisa, kana aluminium sulfate ikasangana nemvura, inopinda hydrolysis, ichigadzira aluminium hydroxide uye sulfuric acid.Iyi kemikari inopindirana yakakosha kune nzira dzekugadzirisa mvura, apo aluminium hydroxide inoshanda se coagulant kubvisa tsvina yakamiswa kubva mumvura.Kudzora kwakaringana nekutarisisa kwakakosha kuti uve nechokwadi chekucheneswa kwemvura uku uchideredza kukanganisa kwezvakatipoteredza.
