Features of Nanoflotation Technique – A Review

Abstract

ABSTRACT
Flotation method is majorly availed in two sectors: mining industry (for separation of metal 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.

Keywords: flotation, industrial waste water, municipal waste water, nanoflotation, treatment
