Abstract: A method and a ventilation system includes ventilation ducts, a control system and at least one spray nozzle. The at least one spray nozzle is configured to spray a liquid mist onto at least one portion of an inner surface of the ventilation system. The liquid mist contains a culture of microorganisms adapted for biologically treating fat, oil and grease present on at least one portion of the inner surface of the ventilation system, thereby providing for partial biodegradation of the fat, oil and grease present on the at least one portion of the inner surfaces of the ventilation system.

Abstract: A method, a system and an apparatus for wastewater treatment using a combination of separation of fat, oil and grease (FOG) and biological treatment for reducing the amount of fat, oil and grease (FOG) in wastewater with the aid of a liquid culture of microorganisms is provided. In particular, the technology disclosed relates to a method and process for the separation and treatment of FOG, as well as a container tank and an outlet pipe construction adapted for improving the gravimetric FOG separation process and the breaking down of FOG using microorganisms.

Abstract: A method, a system, and a wastewater treatment system includes a biological treatment zone for biologically treating fat, oil and grease by adding a culture of microorganisms for partial biodegradation of the fat, oil and grease and/or breaking down the fat, oil and grease. The wastewater system includes a control system, an air injection and distribution system for improving and controlling the biological treatment process and at least one sensor. The at least one sensor may be configured to obtain sensor data, audio data and/or image data, and the control system may be configured to determine the thickness of a layer of fat, oil and grease on the surface of the biological treatment zone.
