Abstract
In this study it is shown that the shear occurring in a sludge cake during dewatering can create an increase in polymer demand. Comparisons between a laboratory mixing unit and a pilot filter press indicate that polymer requirements for mechanical dewatering equipment can be predicted using laboratory procedures.Keywords
