A method of using an ultrasonic system includes positioning at least one component to a ultrasonic system, the ultrasonic system including: an ultrasonic device, comprising a plurality of ultrasonic transducers coupled to a flexible body; a power supply coupled to the ultrasonic device; a fluid vessel configured to supply fluid to the at least one component; and a waste vessel configured to collect the fluid supplied to the ultrasonic device from the fluid vessel. The method includes applying, via the power supply, a current to a plurality of ultrasonic transducers to dislodge a plurality of contaminants from the at least one component. The method includes flushing, via fluid from the fluid vessel, the plurality of contaminants dislodged from the at least one component.

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.

A household appliance includes an outer casing, a water tank and an ice maker. The water tank may be attached to the outer casing. The ice maker is disposed within the outer casing. The ice maker is in fluid communication with the water tank. The household appliance may further include a pump disposed within the outer casing, at least one drain tube attached to the outer casing and a controller. The pump may be in fluid communication with the water tank and the ice maker to flow water from the water tank to the ice maker. The at least one drain tube may define an exit point, the exit point located vertically below the ice mater. The controller may initiate a cleaning cycle that includes pumping a volume of cleaning solution through the ice maker and directing the volume of cleaning solution through the at least one drain tube.
