Two-stage microflotation with particle aggregation

Appendix lOL Two-Stage Microflotation with Particle Aggregation 

Two schemes of combined effects in waste water through introduction of microbubbles and aggregation are known in the literature. Two-stage process flow is characteristic of the first scheme. Aggregation of particles is arranged first and bubble capture follows. 

These examples are presented not only to demonstrate the wide-spread application of microflotation in water purification. It is apparent that optimal technical design (selection of microflotation version and process parameters, such as volume fraction and size of bubbles, hydrodynamic conditions in flotation aggregates, etc.) strongly depends on properties of water which vary over a wide range depending on the plant contaminating the water. Even for one and the same plant waste water varies because of changing conditions of the production
