Dissolved-air flotation in water treatment (a review of foreign literature)

Summary

A review of foreign literature on one of the perspective water treatment technologies, i. e. dissolved-air flotation, is presented. The process of dissolved-air flotation provides for decreasing water turbidity, eliminating algae, Giardia cysts and Cryptosporidium oocysts; whereby, the treatment efficiency is higher compared to sedimentation. The technology ensures efficient removal of low turbidity levels. Overseas, beyond controversy, the tendency of using dissolved-air flotation units for purification of water and wastewater of different origin is increasing.

Key words
