Sludge Processing: sludge composition
organic acids activated to protein pct primary
Sludge processing design parameters — chemical composition and solids concentrations of primary and activated sludge, heavy metals in municipal sludge, sludge quantities by treatment process, gravity thickener loadings, anaerobic and aerobic digestion design criteria, VS loading factors, and cogeneration system efficiency ranges for biogas utilization; from Metcalf & Eddy 5th Ed. Chapter 13
