<p>A process for the treatment of wastewater comprising aerating wastewater containing bacteria until the BOD level of the wastewater is substantially reduced, the food-to- microorganism ratio (F/M) of the wastewater being greater than one, introducing the aerated wastewater under pressure to a dissolved air flotation cell to separate suspended solids, recycling said suspended solids and bacteria to said aeration step in an amount sufficient to maintain said F/M ratio and removing and disposing of the remaining reduced BOD level wastewater. <IMAGE></p> |
