Sodium acetate dareere ah
1. Tilmaamayaasha ugu muhiimsan:
Waxa ku jira: ≥20%, ≥25%, ≥30%
Muuqashada: dareere cad oo hufan, ma laha ur cuncun leh.
Walxaha biyaha aan la milmi karin: ≤0.006%
2. Ujeedada ugu weyn:
Si loo daweeyo bulaacada magaalada, baro saamaynta da'da dhoobada (SRT) iyo isha kaarboonka ee dibadda (sodium acetate solution) ee nidaamka denitrification iyo ka saarista fosfooraska. Sodium acetate waxa loo isticmaalaa il kaarboon ah oo dheeri ah si loo demiyo dhoobada denitrification, ka dibna la isticmaalo xal kaydinta si loo xakameeyo korodhka pH inta lagu jiro habka denitrification gudahooda inta u dhaxaysa 0.5. Bakteeriyada diida waxay u adkeysan kartaa CH3COONa si xad dhaaf ah, sidaa darteed marka CH3COONa loo isticmaalo ilo kaarboon dibadda ah oo loogu talagalay denitrification, qiimaha COD ee wasakhaysan sidoo kale waxaa lagu ilaalin karaa heer hoose. Waqtigan xaadirka ah, daaweynta bulaacada ee dhammaan magaalooyinka iyo gobollada waxay u baahan yihiin inay ku daraan sodium acetate sida il kaarboon si ay ula kulmaan heerarka qiiqa heerka koowaad.
