Raw shredded FVWs were analyzed
more than ten times, and the initial total solids (TS) concentration
and volatile solids (VS) were approximately 100 g/kg and 87 g/kg,
respectively. The total COD (tCOD), soluble COD (sCOD) and
NH4
+
-N were 137.1, 79.3 and 0.07 g/kg, respectively, and the pH
was 4.5–4.8.
