Abstract (en)
[origin: WO2022078868A1] The invention relates to a method for treating waste water, in particular in a vehicle washing system, wherein the treatment takes place along a main waste water flow, and wherein the method comprises at least the following steps: settling the waste water by means of a primary gravitational sedimentation without using a sludge trap in the main waste water flow; and discharging waste water with sedimented sludge from the primary gravitational sedimentation to a secondary gravitational sedimentation with a sludge trip outside the main waste water flow. The invention further relates to a treatment system for waste water in a vehicle washing system, wherein the treatment system has the following: a device for primary gravitational sedimentation, which is disposed within an active region of a main flow of waste water and has no sludge trap in the active region of the main waste water flow; and a device for secondary gravitational sedimentation, which is disposed outside the active region of the main flow of waste water and has a sludge trap.
