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.
Claims11
A waste water treatment process, comprising:
- withdrawing a defined quantity of treated effluent water from a pretreatment additive holding tank;
- combining influent waste water and the defined quantity of treated effluent water in a first treatment tank during a first time interval to produce pretreated water;
- producing separated water by dosing the pretreated water with selective chemical additives formulated to cause separation of solid and liquid media in a second treatment tank during a second time interval;
- substantially removing solid media contained in the separated water with a filter to produce treated effluent water;
- collecting floating sludge from one of the second or a third treatment tank;
- and
- extracting treated effluent water from the floating sludge, wherein a portion of the treated effluent water combined with influent waste water in the first treatment tank is treated effluent water extracted from the floating sludge.
