Maganin ruwan sharar gida: zaɓi tsakanin polyaluminum chloride da aluminum sulfate

A fannin maganin ruwan sharar gida, duka polyaluminum chloride (PAC) da aluminum sulfate ana amfani da su sosai kamar yadda ake amfani da su a fannin maganin sharar gida.masu haɗin gwiwaAkwai bambance-bambance a cikin tsarin sinadarai na waɗannan wakilai guda biyu, wanda ya haifar da aiki da aikace-aikacensu. A cikin 'yan shekarun nan, an fifita PAC a hankali saboda ingancinsa da saurinsa na magani. A cikin wannan labarin, za mu tattauna bambance-bambancen da ke tsakanin PAC da aluminum sulfate a cikin maganin sharar gida don taimaka muku yin zaɓi mai zurfi.

Da farko, bari mu koyi game da polyaluminum chloride (PAC). A matsayinsa na wani abu mai kama da polymer coagulant, PAC yana da kyakkyawan narkewa kuma yana iya samar da flocs cikin sauri. Yana taka rawar coagulation ta hanyar hana lantarki da tarko, kuma ana amfani da shi tare da flocculant PAM don cire datti a cikin ruwan shara yadda ya kamata. Idan aka kwatanta da aluminum sulfate, PAC yana da ƙarfin sarrafawa da ingancin ruwa mafi kyau bayan tsarkakewa. A halin yanzu, farashin tsarkake ruwa na PAC ya fi ƙasa da aluminum sulfate 15-30%. Dangane da shan alkalinity a cikin ruwa, PAC yana da ƙarancin amfani kuma yana iya rage ko soke allurar alkaline.

Na gaba shine aluminum sulfate. A matsayin wani abu na coagulant na gargajiya, aluminum sulfate yana sha kuma yana taruwa da gurɓatattun abubuwa ta hanyar colloids na aluminum hydroxide da hydrolysis ke samarwa. Yawan narkewar sa ba shi da kyau, amma ya dace da maganin ruwan shara tare da pH na 6.0-7.5. Idan aka kwatanta da PAC, aluminum sulfate yana da ƙarancin ƙarfin magani da ingancin ruwa mai tsafta, kuma farashin tsarkake ruwa yana da yawa.

Dangane da girman aiki, PAC da aluminum sulfate suna da ɗan bambanci kaɗan; PAC gabaɗaya yana da sauƙin sarrafawa kuma yana samar da flocs cikin sauri, wanda ke inganta ingancin magani. A gefe guda kuma, aluminum sulfate yana jinkirin narkewa kuma yana iya ɗaukar lokaci mai tsawo kafin ya taru.

Aluminum sulfatezai rage pH da alkalinity na ruwan da aka yi wa magani, don haka ana buƙatar soda ko lemun tsami don rage tasirin. Maganin PAC yana kusa da tsaka tsaki kuma babu buƙatar wani abu mai hana ruwa shiga (soda ko lemun tsami).

Dangane da ajiya, PAC da aluminum sulfate yawanci suna da karko kuma suna da sauƙin adanawa da jigilar su. Yayin da ya kamata a rufe PAC don hana sha danshi da kuma fuskantar hasken rana.

Bugu da ƙari, daga mahangar lalata, aluminum sulfate yana da sauƙin amfani amma ya fi lalata. Lokacin zabar coagulants, ya kamata a yi la'akari da tasirin duka biyun akan kayan aikin magani.

A takaice,Polyaluminum Chloride(PAC) da aluminum sulfate suna da nasu fa'idodi da rashin amfani a fannin tsaftace najasa. Gabaɗaya, PAC a hankali tana zama babban coagulant saboda ingantaccen aiki, iyawarta ta sarrafa ruwan shara cikin sauri da kuma fa'idar daidaita pH. Duk da haka, aluminum sulfate har yanzu yana da fa'idodi marasa maye gurbinsu a wasu yanayi. Saboda haka, lokacin zabar coagulant, ya kamata a yi la'akari da abubuwa kamar ainihin buƙata, tasirin magani da farashi. Zaɓi coagulant mai dacewa zai taimaka wajen inganta ingancin maganin shara.
