WitrynaThe atomic ratio of H/C versus O/C for organic sludge and derived hydrochar were shown in the Van Krevelen Diagram (Figure 2). The Van Krevelen Diagram was used to investigate the coalition effect of hydrothermal carbonization. The initial ratios of H/C and O/C in organic sludge were 2.08 and 0.58 respectively.
Witryna5.3.2.4 Sludge loading or organic loading rate. The SL or ratio of feed to microorganism (F/M) is an important design parameter in the MBR process. Generally, the MBR process can operate at higher F/M ratios compared with an activated sludge plant ( Robinsion, 2003 ). It is defined as kilograms of COD divided by kilograms of MLSS times days.
