Comment on "experimental analysis of centrifugal dewatering process of polyelectrolyte flocculated waste activated sludge".
In summary, after supernatant liquid was exhausted in the author's experiments, menisci formed, and shrinkage, not pore evacuation and drying, was the mechanism causing removal of water thereafter. Results of centrifugal filtration experiments cannot be applied to solid bowl centrifugation because solid compression conditions are quite different in the two types of machines.
