Disclosed is systems and methods for cleaning devices holding fluid such as heat exchanges. The cleaning is performed by using a system such as a transducer assembly including a mechanical wave generator and a waveguide including a cavity. The system is capable of operating at its fundamental resonance frequency even when connected to an outer surface of the device to be cleaned.

The firearm barrel cleaning system selectively cycles a stream of ultrasonic cleaning fluid through the barrel of a firearm, and further selectively ultrasonically induces cavitation within the cleaning fluid in the barrel for ultrasonic cleaning. The firearm barrel cleaning system includes a receiver assembly having a first end adapted for receiving the stream of cleaning fluid and a second end is adapted for insertion into the firearm receiver and sealing against a first end of the barrel to eject the stream of cleaning fluid into the barrel. A cap structure, having an outlet hose connector is clamped over the muzzle end of the barrel of the firearm. A pump selectively circulates the cleaning fluid through the receiver assembly, the barrel and out through the cap structure. An ultrasonic transducer is mounted on the receiver assembly for selectively inducing cavitation in the cleaning fluid.

Various automated cleaning systems for internal cavities of pressure instruments are disclosed. The systems comprise a computer controlled fluid flow system that enables the use of various cleaning fluids for cleaning internal cavities of pressure instruments to high cleanliness levels. Various pressure instruments, including complex shapes such as Bourdon tube gauges, are accommodated. The system can include a computerized cleaning cycle selection and a multi-fluid combination of cleaners for efficient and low cost cleaning solution. A servo controlled agitation system can allow for filling, evacuation, and drying of aqueous solutions as well as high performance solvents for Oxygen Clean service.

A method is provided for non-intrusively determining deposits of a fluidic channel. The method includes creating a pressure pulse in a fluidic channel. The method also includes sensing, by one or more sensors, reflections of the pressure pulse; and obtaining, from the one or more sensors, a measured pressure profile based on the sensed reflections of the pressure pulse. A processor then can determine one or more properties of the deposit in the fluidic channel based on the measured pressure profile.

Pulse dosing is used to administer a cleaning formulation into a fluid process stream flowing through structural components of a processing facility. The fluid process stream may contain corn, corn-derived products, or a combination thereof, or the fluid process stream may contain a process condensate, a rinse fluid, a cleaning fluid or any combination thereof. The processing facility may be an ethanol processing plant, a protein processing plant, a corn oil processing plant, an ethanol and corn oil processing plant, an ethanol and protein processing plant, or an ethanol, corn oil and protein processing plant. Pulse dosing may include administering the cleaning formulation into the fluid process stream for a period of x seconds every y minutes, with no administration of the cleaning formulation between the periods of x seconds.

A method of cleaning a contaminated surface, such as cleaning the elongate interior lumen of an endo scope contaminated with flesh, bone, blood, mucous, faeces or biofilm, said method comprising the steps of: providing a suspension of solid particles in a liquid to said contaminated surface, and flowing said suspension along said surface thereby to remove contaminant from the surface. The suspension is preferably a paste, where the solid material may be e.g. crystals of a salt, silicon oxide or organic material. The paste preferably has a solid fraction between 5 and 55%. A rheology modifier may be present.

A method for cleaning firearm suppressors comprising: providing a used suppressor having an internal cavity with a fouling material deposited on a surface of the internal cavity; providing a cleaning solution; providing an ultra-sonic probe; introducing the cleaning solution into the internal cavity of the used suppressor; contacting at least part of the ultra-sonic probe with the cleaning solution that is introduced inside the internal cavity of the used suppressor; operating the ultra-sonic probe; removing at least part of the fouling material from the surface of the internal cavity of the used suppressor; and, draining the cleaning solution from the used suppressor.
