Aruminiyamu sulfate, inomiririrwa nemakemikari seAl2(SO4)3, isimbi chena yekristaro inowanzoshandiswa mukurapa mvura. Kana aruminiyamu sulfate ikapindirana nemvura, inonyungudika, iyo makemikari anoita kuti mamorekuru emvura apatsanure chinhu ichi kuita maion ayo. Iyi makemikari inoita basa rakakosha mukushandiswa kwakasiyana-siyana, kunyanya mukuchenesa mvura.
Chinhu chikuru chinobuda mukuita uku ialuminium hydroxyl complex. Iyi complex inokosha pakugadzirisa mvura, sezvo ichibatsira kubvisa tsvina mumvura. Aluminum hydroxyl complex ine simba rakawanda, uye kana yagadzirwa, inokwanisa kubata nekusunga zvidimbu zvakasungirirwa, zvakaita sevhu, silt, nezvimwe zvinhu zvipenyu. Nekuda kweizvozvo, tsvina iyi diki inova huru uye inorema, zvichiita kuti zvive nyore kuti igare mumvura.
Sulfuric acid inogadzirwa mu reaction inoramba iri mumusanganiswa uye inobatsira mukuwedzera acidity yesystem. Acid inogona kugadziriswa sezvinodiwa, zvichienderana nezvinodiwa zvekugadzirisa mvura. Kudzora pH kwakakosha pakugadzirisa kushanda zvakanaka kwe coagulation uye flocculation processes. Zvinoderedzawo alkalinity yemvura. Kana alkalinity yemvura yedziva pachayo yakaderera, saka NaHCO3 inofanira kuwedzerwa kuti iwedzere alkalinity yemvura.
Kubatana pakati pealuminium sulfate nemvura kunowanzo shandiswa mumatanho ekuomesera uye ekupwanya kwemvura mumafekitori ekuchenesa mvura. Kupwanya kunosanganisira kusagadzikana kwezvikamu zvakamiswa, ukuwo kupwanya kuchiita kuti zvikamu izvi zviunganidzwe kuita zvikamu zvikuru, zvinogadziriswa nyore nyore. Maitiro ese ari maviri akakosha pakubvisa tsvina uye kujekesa mvura.
Zvakakosha kuziva kuti kushandiswa kwealuminium sulfate mukuchenesa mvura kwakakonzera matambudziko ezvakatipoteredza nekuda kwekuwanda kwealuminium mumvura. Kuti kuderedze matambudziko aya, kuongororwa kwakanyatsojeka uye kuongororwa kwakakosha kuitira kuti huwandu hwealuminium mumvura yakarapwa huenderane nezvinodiwa nemutemo.
Mukupedzisa, kana aruminiyamu sulfate ikapindirana nemvura, inonyungudika, ichigadzira aruminiyamu hydroxide uye sulfuric acid. Kusangana uku kwemakemikari kwakakosha pakugadzirisa mvura, apo aruminiyamu hydroxide inoshanda se coagulant yekubvisa tsvina yakamiswa mumvura. Kudzora nekutarisa kwakakodzera kunodiwa kuti mvura icheneswe zvakanaka uku ichideredza kukanganiswa kwezvakatipoteredza.
