Maganin sharar gida: zaɓi tsakanin polyaluminum chloride da aluminum sulfate

A fagen kula da ruwan sha, duka polyaluminum chloride (PAC) da aluminum sulfate ana amfani da su sosai.coagulanti. Akwai bambance-bambance a cikin tsarin sinadarai na waɗannan wakilai biyu, wanda ke haifar da aikinsu da aikace-aikacensu. A cikin 'yan shekarun nan, an sami fifikon PAC a hankali don ingantaccen ingancin magani da saurin sa. A cikin wannan labarin, za mu tattauna bambance-bambance tsakanin PAC da aluminum sulfate a cikin maganin ruwa mai tsabta don taimaka muku yin zaɓin da ya dace.

Da farko, bari mu koyi game da polyaluminum chloride (PAC). A matsayin inorganic polymer coagulant, PAC yana da kyakkyawan narkewa kuma yana iya samar da flocs cikin sauri. Yana taka rawar coagulation ta hanyar tsaka-tsakin wutar lantarki da tara tarko, kuma ana amfani da shi tare da flocculant PAM don kawar da ƙazanta a cikin ruwan datti. Idan aka kwatanta da aluminum sulfate, PAC yana da ƙarfin sarrafawa da ingantaccen ingancin ruwa bayan tsarkakewa. A halin yanzu, farashin tsarkakewar ruwa na PAC shine 15% -30% ƙasa da aluminum sulfate. Dangane da cinye alkalinity a cikin ruwa, PAC yana da ƙarancin amfani kuma yana iya rage ko soke allurar wakili na alkaline.

Na gaba shine aluminum sulfate. A matsayin coagulant na gargajiya, aluminum sulfate yana adsorbs kuma yana daidaita gurɓatacce ta hanyar aluminum hydroxide colloid da hydrolysis ke samarwa. Adadin narkar da shi ba shi da ɗanɗano kaɗan, amma ya dace da kula da ruwan sha tare da pH na 6.0-7.5. Idan aka kwatanta da PAC, aluminum sulfate yana da ƙarancin jiyya da ingancin ruwa mai tsabta, kuma farashin tsaftace ruwa yana da girma.

Dangane da girman aiki, PAC da aluminum sulfate suna da aikace-aikace daban-daban; PAC gabaɗaya yana da sauƙin ɗauka kuma yana samar da ƙungiyoyi cikin sauri, wanda ke haɓaka ingantaccen magani. Aluminum sulfate, a gefe guda, yana jinkirin yin ruwa kuma yana iya ɗaukar lokaci mai tsawo don daidaitawa.

Aluminum sulfatezai rage pH da alkanility na ruwan da aka bi da su, don haka ana buƙatar soda ko lemun tsami don kawar da tasirin. Maganin PAC yana kusa da tsaka tsaki kuma babu buƙatu don kowane wakili na tsaka tsaki (soda ko lemun tsami).

Dangane da ajiya, PAC da aluminum sulfate yawanci barga ne da sauƙin adanawa da jigilar kaya. Yayin da ya kamata a rufe PAC don hana ɗaukar danshi da fallasa hasken rana.

Bugu da ƙari, daga ra'ayi na lalata, aluminum sulfate yana da sauƙin amfani amma ya fi lalacewa. Lokacin zabar coagulant, tasirin tasirin duka biyu akan kayan aikin magani yakamata a yi la'akari sosai.

A takaice,Polyaluminum chloride(PAC) da aluminum sulfate suna da nasu fa'idodi da rashin amfani a cikin kula da najasa. Gabaɗaya, PAC sannu a hankali yana zama babban coagulant saboda babban ingancinsa, saurin maganin ruwan sharar gida da kuma faffadan daidaitawar pH. Koyaya, aluminum sulfate har yanzu yana da fa'idodin da ba za a iya maye gurbinsu ba a wasu yanayi. Sabili da haka, lokacin zabar coagulant, abubuwa kamar ainihin buƙata, tasirin magani da farashi yakamata a yi la'akari da su. Zaɓin maganin coagulant mai kyau zai taimaka inganta ingantaccen maganin ruwa.
