Optimization of Flocculation in Connection with Various Solid-Liquid Separation Processeser treatment have postulated sedimentation and/or filtration as the typical accompanying separation processes. Therefore, much data is available on optimal coagulation and flocculation conditions defined on the basis of the above stream. Very often “good floe” was defined according to a conventional

Colloid Destabilization in the Treatment of Surface Waters Containing Colloid-Stabilizing Pollutantsf surface waters. Hydrolysis causes the aforementioned metal salts to transform into metal hydroxides, the particles of which aggregate into floes accessible to sedimentation and filtration, i.e., to simple solid-liquid phase separation operations. The solid particles present as colloidal and quasi-

Floc Strength in Bridging Flocculationew approaches for attaining the maximum stable floc size in turbulent flow have been derived taking into account both the influence of hydrodynamics and particle adhesion within the floc. Modeling is based on the assumption that fluid eddies of the scale of aggregate size are responsible for the des
