Bambanci tsakanin sulfate na ƙarfe da sulfate na polyferric

Babban bambance-bambance tsakanin ferrous sulfate da polymeric ferric sulfate ana nuna su a cikin kaddarorin sinadarai, tasirin magani, yanayin aikace-aikace da daidaitawar muhalli, kamar haka:

I. Halayen sinadarai da tsari

1. Tsarin sinadarai da yanayin ion na ƙarfe

● Iron sulfate: tsarin sinadaran shine FeSO₄·7H₂O, ƙarfe yana da divalent (Fe²⁺), yana cikin ƙananan ƙwayoyin halitta marasa kwayoyin halitta. Yana da kaddarorin ragewa kuma yana iya amsawa tare da chromium hexavalent da sauran gurɓatattun abubuwa ta hanyar amsawar REDOX.
● Polyferric sulfate: Tsarin sinadarai shine [Fe₂(OH)ₙ(SO₄)₃-ₙ/₂]ₘ, tare da ƙarfe a cikin yanayin trivalent (Fe³⁺), yana cikin polymers marasa tsari. Bayan hydrolysis, yana samar da hadaddun makaman nukiliya da yawa (kamar [Fe₂(OH)₄]²⁺), waɗanda ke cire gurɓatattun abubuwa ta hanyar shaƙa da kuma rarraba wutar lantarki.

2. kadarar jiki

● Iron sulfate: kore mai haske ko rawaya mai haske mai ƙarfi, mai sauƙin cirewa, ruwan yana da haske kore; yana buƙatar kasancewa cikin yanayi mai ɗan alkaline (pH 8-10) don cimma mafi kyawun sakamako.
● Polyferric sulfate: foda/ruwa mai launin ruwan kasa mai launin rawaya ko ja, ƙarancin narkewa, amma pH mai faɗi iri-iri (4-11), musamman ya dace da ƙarancin zafin jiki, ingancin ruwa mai tururi.

II. Fagen aikace-aikace da tasirin sarrafawa

1.ferrisulfas

● Halayen aiki:
● Yana da kaddarorin ragewa (kamar rage hexavalent chromium zuwa trivalent chromium), halayen coagulation da kuma halayen cire launi.
     ● Tasirin canza launin yana da ƙarfi, kuma ruwan sharar rini mai amsawa na iya zama kusan babu launi bayan an yi masa magani.
● babban aikace-aikace:
● Ruwan sharar gida mai haske (an yi masa magani da ƙarfe masu nauyi kamar chromium da jan ƙarfe).
● Noma (ƙarin ƙarfe), magungunan kashe ƙwayoyin cuta na masana'antu.

2.Polyferric sulfate

● Halayen aiki:
● Yawan cire COD da BOD ya kasance kashi 80% da 93% bi da bi ta hanyar shaye-shaye da kama tarin hadaddun makaman nukiliya da yawa.
● Tasirin canza launi ya ɗan yi rauni kaɗan fiye da na ferrous sulfate (94%-98% idan aka kwatanta da kusan babu launi), amma ya fi inganci wajen cire COD.
● babban aikace-aikace:
● Tsaftace ruwa, Ruwan sharar masana'antu (rini, yin takarda, yin amfani da wutar lantarki, da sauransu), cire ruwa daga laka.
● Ƙananan zafin jiki ko yawan danshi Maganin Ruwa.

Farashi da tasirin muhalli

● Iron sulfate: ƙarancin farashi, amma yana da sauƙin oxidize kuma yana lalacewa. Yin amfani da shi fiye da kima zai haifar da ragowar ions na ƙarfe a cikin ruwa, wanda zai iya haifar da gurɓataccen abu na biyu.
● Polyferric sulfate: yawan maganin shine kashi 20%-50% na ferrous sulfate, ƙarancin laka kuma yana da sauƙin bushewa, babu ragowar aluminum da chlorine, ingantaccen kariya ga muhalli.

taƙaitawa

Ferrous sulfate ya dace da maganin rage gurɓatattun abubuwa (kamar hexavalent chromium) da kuma yanayin da ba shi da tsada, yayin da polymeric ferric sulfate ya fi inganci kuma yana da kyau ga muhalli, ya dace da tsaftace ruwa mai rikitarwa. Ya kamata a haɗa ainihin zaɓin tare da nau'in gurɓatattun abubuwa, buƙatun magani da kasafin kuɗi.
