The influence of several parameters on removal of various impurities during vacuum flotation clarification of mixed juice has been investigated, and possible ways of dealing with the secondary precipitate obtained in this clarification process have been examined. Dispersed a~ir flotation clarification is described and the experience gained with this separation technique is recorded. Introductio...

We report on the mechanisms and application of dextran-graft-polyacrylamide star-like polymers as efficient flocculation aids. Demonstrated in this paper is that these form complexes with three common radionuclide contaminants: uranium, strontium, cesium. Application flocculant aids together inexpensive kaolinite-like materials allows fast purification water. The methods presented here can be e...

Liquid livestock waste can be managed by separating liquid and solid fractions then treating each separately by applying best available technology, such as anaerobic digestion for the solid fraction. There is an increasing use of polyacrylamide (PAM) as a flocculant agent to improve solid-liquid separation. In the present work, the anaerobic toxicity of PAM residues and the optimal range of tot...
