  • Patent number: 10851004
    Abstract: Provided is a method and device for a waste water treatment process. In one exemplary embodiment influent waste water and a defined portion of treated effluent water are combined during a first time interval to produce pretreated water. The pretreated water is dosed with selective chemical additives formulated to cause separation of solid and liquid media during a second time interval, producing separated water. Remaining solid media is removed from the separated water with a sludge filter to produce treated effluent water.
