ores) and in wastewater treatment process (both for municipal and industrial wastewaters)
for separation of suspended solids, emulsions, chemical sludge or excess sludge. Traditional
flotation relies on floating of solids (mainly suspended solids) on the top of the liquid by air
bubbles (in conventional process they have and average diameter of 100–300 μm). Better
separation effect is obtained when air bubbles are very small (micro and nano). Special
dispersing pumps are able to create air–water mixture of nanobubbles and process is termed as micro- and nanoflotation.
