Abstract

A vacuum collection tank (12) having apparatus for dissipating foam is disclosed. The vacuum collection tank (12) is connected to a vacuum generator (16) to create a vacuum level in the tank. A transport pipe (20) is also connected to the tank to allow flow of waste water into the tank (12). A drain (22,24) is provide at a bottom of the tank (12) for discharging the contents of the tank. A foam detector (32) is provided for sensing foam inside the (12) tank and triggering a discharge operation, thereby to remove the foam from the tank. Alternatively, an anti-foam assembly may be provided for discharging an anti-foam agent into the tank, wherein the anti-foam agent is discharged in response to a foam signal from the foam detector.
