Aluminium Sulfate, Chemically sawv cev raws li Al2 (so4) 3, yog ib qho dawb crystalline cov khoom uas siv tau hauv cov txheej txheem dej kho. Thaum aluminium sulfate reacts nrog dej, nws undergoes hydrolysis, tshuaj lom neeg nyob rau hauv uas cov dej lwg uas tawg rau hauv nws lub chaw ua ke. Qhov tshuaj tiv thaiv no ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv, tshwj xeeb hauv dej huv huv.
Thawj cov khoom ntawm cov tshuaj tiv thaiv no yog txhuas hydoxhoyl complex. Qhov nyuaj no yog qhov tseem ceeb heev nyob rau hauv kev kho dej dej, raws li nws pab tau hauv kev tshem tawm ntawm impurities los ntawm dej. Aluminium Hydroxyl Complex muaj tsub nqi zog, thiab thaum tsim, nws yog coaguling txwv li, xws li av nplaum, sit, thiab cov organic. Raws li qhov tshwm sim, cov me me impurities ua loj dua thiab hnyav dua cov lus, ua rau nws yooj yim rau lawv los khom ntawm cov dej.
Cov sulfuric acid tsim nyob rau hauv cov kev tshuaj tiv thaiv tseem nyob hauv kev daws teeb meem thiab ua rau muaj peev xwm tshaj tawm ntawm cov kab ke. Cov acidity tuaj yeem hloov kho raws li xav tau, nyob ntawm cov kev cai tshwj xeeb ntawm cov txheej txheem kev kho dej. Tswj cov pH yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm kev ua kom muaj kev ua tau zoo ntawm kev sib cav thiab cov txheej txheem flocculation. Nws tseem yuav txo cov alkalinity ntawm dej. Yog hais tias tus Alkalinity ntawm pas dej dej nws tus kheej yog tsawg, ces Nahco3 xav tau ntxiv kom ntxiv rau lub alkalinity ntawm dej.
Cov tshuaj tiv thaiv ntawm Aluminium Sulfate thiab dej feem ntau ua haujlwm hauv kev cog ntoo thiab flocculation ntawm cov dej kho cov nroj tsuag. Coagulation koom nrog txoj kev ua kom tiav ntawm cov ntawv raug tshem tawm, thaum lub sij hawm flocculation txhawb nqa kev sib sau ua ke ntawm cov khoom loj, yooj yim tau flatable flocs. Ob qho tib si txheej txheem tseem ceeb heev rau kev tshem tawm ntawm impurities thiab kev qhia meej ntawm cov dej.
Nws yog ib qho tseem ceeb kom nco ntsoov tias kev siv cov txhuas sulfate tau tsa kev txhawj xeeb ib puag ncig vim yog cov peev xwm tsub zuj zuj ntawm etatic ecosystems. Txhawm rau txo cov kev txhawj xeeb no, kev qhia meej thiab saib xyuas yog qhov tseem ceeb kom ntseeg tau tias txhuas cov kev ua kom pom cov qauv dej.
Hauv kev xaus, thaum txhuas sulfate reacts nrog dej, nws undergoes hydrolysis, tsim ua txhuas hydroxide thiab sulfuric acid. Cov tshuaj lom neeg siv tshuaj no yog qhov tseem ceeb rau cov txheej txheem kev kho dej, qhov twg cov txhuas hydroxide ua rau tshem tawm cov dej tsis txaus los ntawm dej. Kev tswj kom zoo thiab saib xyuas yog qhov tsim nyog los xyuas kom meej cov dej huv thaum muaj kev cuam tshuam ib puag ncig ib puag ncig.
