Study on Sodium Acetate Carbon Source's Effect on Activated Sludge Settleability

Studies show that appropriate sodium acetate dosing to supplement carbon improves denitrification and promotes sludge microbial balance, helping activated sludge settle; overdose or uneven dosing may cause local sludge bulking.

Operation should dose evenly, control total amount, and monitor SVI. Reasonable sodium acetate dosing is one basis for stable sludge settlement and compliance.
