Abstract

See full text

A method and apparatus of minimizing the loss of liquid in a dissolved air flotation desludging process, is disclosed. The method and apparatus creates an ambient airflow over the top of the dissolved air flotation tank directed towards a weir at one end of the dissolved air flotation tank whereby sludge floating on top of the liquid is accelerated over the weir at a higher rate than the liquid, thereby conserving the amount of liquid lost over the weir.
