▁water ▁with ▁air . ▁The ▁air - s atur ated ▁water ▁stream ▁is ▁rec yc led ▁to ▁the ▁front ▁of ▁the ▁Micro fl ot ation ▁cell ▁and ▁flows ▁through ▁a ▁pressure ▁release ▁val ve ▁just ▁as ▁it ▁enters ▁the ▁front ▁of ▁the ▁float ▁tank , ▁which ▁results ▁in ▁the ▁air ▁being ▁released ▁in ▁the ▁form ▁of ▁tiny ▁b ub bles . ▁B ub bles ▁form ▁at ▁nucle ation ▁sites ▁on ▁the ▁surface ▁of ▁the ▁susp ended ▁particles , ▁ad her ing ▁to ▁the ▁particles . ▁As ▁more ▁b ub bles ▁form , ▁the ▁lift ▁from ▁the ▁b ub bles ▁eventually ▁over comes ▁the ▁force ▁of ▁gravity . ▁This ▁causes ▁the ▁susp ended ▁matter ▁to ▁float ▁to ▁the ▁surface ▁where ▁it ▁forms ▁a ▁fro th ▁layer ▁which ▁is ▁then ▁removed ▁by ▁a ▁sk immer . ▁The ▁fro th - free ▁water ▁ex its ▁the ▁float ▁tank ▁as ▁the ▁clar ified ▁eff lu ent ▁from ▁the ▁Micro fl ot ation ▁unit . ▁A ▁particular ▁circular ▁D AF ▁system ▁is ▁called ▁" Zero ▁speed ", ▁allowing ▁quite ▁water ▁status ▁then ▁highest ▁performances ; ▁a ▁typical ▁example ▁is ▁an ▁E asy float ▁ 2 K ▁D AF ▁system . ▁ ▁Adv antages ▁ ▁Micro fl ot ation ▁is ▁an ▁en hanced ▁method ▁to ▁float ▁particles ▁to ▁the ▁surface ▁with ▁the ▁aid ▁of ▁ad her ent ▁air ▁b ub bles . ▁ ▁The ▁ad her ence ▁of ▁susp ended ▁sol ids ▁to ▁b ub bles ▁is ▁easier ▁and ▁more ▁int ensive , ▁the ▁smaller ▁the ▁b ub bles
