When dilute liquid overfloxv is acceptable because high wash water ratios are used for high temperature operation, when anticipate changes in feed materials and if the filtration rate is 140 g/s rtf. 

Wash ratio 2-2.2 water to 1 solids. Wash ratio and the number of stages are selected for expected recovery. 

Add one more thickening stage to account for inefficiencies in mixing.
