Kalmomin Mahimmanci: Aluminum Sulfate, Ferrous Sulfate, Polyaluminum Chloride (PAC), Polyacrylamide (PAM)
Aluminum sulfate wani sinadari ne da ba shi da sinadarai wanda aka saba amfani da shi wanda ke da dabarar sinadarai ta Al₂(SO₄)₃, nauyin kwayoyin halitta na 342.15, da kuma farin siffa ta lu'ulu'u. A matsayinsa na wani muhimmin sinadari a fannin maganin ruwa, aikinsa na asali ya ta'allaka ne kan samar da barbashi masu dauke da sinadarin colloidal ta hanyar sinadaran hydrolysis; wadannan barbashi suna shakewa da kuma fitar da daskararru, colloids, da wasu datti da aka narkar a cikin ruwa, ta haka ne ake samun tsarkake ruwa. Yanayin amfani da shi ya shafi fannoni daban-daban, ciki har da maganin ruwan sha, maganin sharar gida na masana'antu, shirya masu auna rosin a masana'antar yin takarda, da kuma canza launin man fetur.
I. Ka'idojin Fasaha da Ayyukan Musamman:
Idan aluminum sulfate ya narke a cikin ruwa, ions na aluminum (Al³⁺) suna haɗuwa da ƙwayoyin ruwa don samar da ions na aluminum masu ruwa, waɗanda daga baya za a ƙara yin hydrolysis don samar da colloids na aluminum hydroxide. Saman waɗannan colloids suna ɗauke da caji mai kyau, wanda ke ba su damar kawar da cajin mara kyau akan barbashi da aka dakatar a cikin ruwa. Wannan hanawa yana kawo cikas ga kwanciyar hankalin barbashi, yana haɓaka taruwar su zuwa manyan flocs (clumps), waɗanda a ƙarshe aka raba su ta hanyar sedimentation ko tacewa. Wannan duka tsari ana kiransa da "coagulation-sedimentation" kuma yana ɗaukar muhimmin mataki a cikin maganin ruwa. Bugu da ƙari, aluminum sulfate na iya amsawa tare da wasu ions na ƙarfe masu nauyi da ke cikin ruwa (kamar ƙarfe da manganese) don samar da abubuwan da ba sa narkewa, ta haka yana taimakawa wajen kawar da gurɓatattun abubuwa da suka narke.
Kamfanin Aojin Chemical yana bayar da nau'ikan kayayyakin tace ruwa iri-iri, wadanda suka hada da aluminum sulfate, ferrous sulfate,Polyaluminum Chloride (PAC), kuma Polyacrylamide (PAM)Ana ƙarfafa abokan ciniki su zaɓi samfura gwargwadon buƙatunsu. Muna maraba da duk wanda ke buƙatar samfuran tace ruwa ya tuntuɓi Aojin Chemical!
II. Yanayin Aikace-aikace da La'akari da Aiki:
A cikin maganin ruwan sha, yawanci ana amfani da aluminum sulfate tare da kayan taimako na coagulant - kamar carbon mai aiki ko polyacrylamide - don kawar da turbidity, algae, da kwayoyin halitta yadda ya kamata. A cikin maganin sharar gida na masana'antu, dole ne a daidaita yawan aluminum sulfate bisa ga ƙimar pH na ruwan: a ƙarƙashin yanayin acidic, hydrolysis na aluminum ions yana ci gaba yadda ya kamata; duk da haka, yawan shan ƙwayoyi na iya haifar da ragowar matakan aluminum a cikin ruwan da aka yi wa magani wanda ya wuce iyakokin ƙa'idodi. Akasin haka, a cikin yanayin alkaline, ya zama dole a ƙara wakilai masu daidaita pH (kamar lemun tsami) don inganta ingancin flocculation. A cikin masana'antar yin takarda, aluminum sulfate yana aiki a matsayin wakili mai girma don girman rosin; yana amsawa da rosin acid don samar da sabulun aluminum mara narkewa, don haka yana haɓaka juriyar ruwa na takarda. A fannin canza launin mai, ana amfani da kaddarorin adsorptive na mahaɗin don cire danko da asfaltenes daga samfuran mai. III. Fa'idodin Fasaha da Aiki Mai Amfani:
Idan aka kwatanta da sauran flocculants (kamar gishirin ƙarfe), aluminum sulfate yana da halaye masu zuwa: Na farko, colloidal aluminum hydroxide da ake samarwa yayin hydrolysis yana da girman barbashi iri ɗaya da ingantaccen flocculation mai yawa, don haka yana rage yawan sinadarin da ake buƙata na sinadarin. Na biyu, yana da tasiri a cikin kewayon pH mai faɗi (5.5–8.5), yana kawar da buƙatar daidaita acidity ko alkalinity na ruwan. Na uku, ana iya ƙara cire ions na aluminum da suka rage ta hanyar hanyoyin magani na gaba (kamar tace yashi ko kunna carbon adsorption), ta haka yana rage haɗarin gurɓatawa na biyu. Bayanan gwaji sun nuna cewa lokacin da ake magance ruwan kogi mai yawan turbidity, adadin aluminum sulfate na 30–50 mg/L zai iya cimma ƙimar cire turbidity fiye da 90%, yana tabbatar da cewa ruwan da aka yi wa magani ya cika ƙa'idodin tsafta don ruwan sha na gida.
IV. Jagororin Tsaro da Ajiya:
Yana da mahimmanci a guji adanawa tare da tushe mai ƙarfi ko kuma sinadaran oxidizing masu ƙarfi don hana tasirin iskar oxygen daga waje. Dole ne a kiyaye yanayin ajiya a bushe kuma a kiyaye shi a zafin da bai wuce 50°C ba don hana samfurin shan danshi da cake. A lokacin mu'amala, ya kamata a sa safar hannu da gilashin kariya don hana shaƙar ƙura ko taɓa fata. Idan aka yi kuskure a ido, nan da nan a wanke da ruwa mai tsafta kuma a nemi taimakon likita. A lokacin jigilar kaya, dole ne a ɗauki matakan kariya don kare samfurin daga danshi da lalacewar jiki, don tabbatar da ingancin marufin.
