An approach for treating a fluid transport conduit with ultraviolet radiation is disclosed. A light guiding unit, operatively coupled to a set of ultraviolet radiation sources, encloses the fluid transport conduit. The light guiding unit directs ultraviolet radiation emitted from the ultraviolet radiation sources to ultraviolet transparent sections on an outer surface of the fluid transport conduit. The emitted ultraviolet radiation passes through the ultraviolet transparent sections, penetrates the fluid transport conduit and irradiates the internal walls. A control unit adjusts a set of operating parameters of the ultraviolet radiation sources as a function of the removal of contaminants from the internal walls of the fluid transport conduit.

A back-blush cleaning container may have a spring-biased piston that allows the container to fill with hot water when attached to a group head of the espresso machine. When the hot water of the espresso machine is turned off, the piston due to the spring urges the hot water out and back through a 3-way valve to clean the espresso machine. The backflush cleaning container also may have a steam conduit that allows steam from a steam wand of the espresso machine to clean the group head, 3-way valve and tubes. Moreover, the container may have a window which based on the position of the piston, a particular color is shown. The colors indicate whether the container is safe to remove from the group head of the espresso machine and when the container is full of water.

Disclosed herein is a cleaning ammunition for facilitating cleaning of a projectile launching system, in accordance with some embodiments. Accordingly, the cleaning ammunition may include a casing and a cleaning projectile. Further, the casing traversable through a barrel of the projectile launching system. Further, the casing may include a proximal end and a distal end. Further, the casing may include a propellant disposed within an interior space of the casing at the proximal end. Further, the casing may include a primer disposed alongside the propellant. Further, the primer is configured to ignite the propellant based on a striking force receivable from a launching mechanism of the projectile launching system. Further, the cleaning projectile disposed within the interior space adjacent to the propellant. Further, the cleaning projectile is disposed at the distal end of the casing. Further, the cleaning projectile may be configured for performing a cleaning action on the barrel.

A system for cleaning a downspout of an eavestrough system where the downspout comprises a downwardly extending pipe with a bottom discharge portion having a mouth utilizes an air blower system which can be a leaf blower or a shop vacuum with an outlet nozzle. The system includes a connector portion in the form of a flexible sleeve having first and second open ends and a tightening system such as a strap at each end. In use the first end is tightened onto the outlet nozzle of the air blower and the second end is tightened onto the discharge portion at the mouth and the air blower system is operated to drive air through the downspout to expel any collected materials.

The invention relates to a diffusor for adding of gases into water, said diffusor comprising a perforated tube (1) and at least one supply tube (2), said the at least one supply tube (2) is at one end coupled to a source for supplying gas and at the other end in fluid communication with the perforated tube (1), the gas is supplied to the perforated tube (1) through at least one inner supply tube (4; 5; 15) extending from the supply tube (2) to the perforated tube (1). The invention is distinctive in that at the least one inner supply tube (4; 5; 15) is a non-perforating tube and has at least one outlet (4a, 5a, 15a) situated at a free end of the at least one inner supply tube (4, 5, 15), said gas is adapted to be distributed into the perforated tube (1) through the at least one outlet (4a, 5a, 15a).

A clean-in-place process may begin with a pre-rinse step in which soil (e.g., contaminants, residual product) is flushed from industrial equipment prior to circulating a cleaning agent through the equipment. To determine when the equipment has been suitably flushed, pre-rinse fluid exiting the industrial equipment and containing soil may be fluorometrically analyzed. A concentration of the soil is determined from fluorescent emissions emitted by the soil itself. Based on this information, the pre-rinse flushing process can be controlled, for example, to minimize water usage, maximize pre-rinse cleaning, or based on any other suitable metric.

A collection apparatus for collecting waste from cleaning operations performed on an aircraft turbine engine includes a frame structure, a support arm having a first end movably attached to the frame structure and an opposite second end, an actuator device adapted to enable raising and lowering the support arm, a waste storage tank, a duct having an inlet end and an opposite outlet end adapted to be removably connected to the waste storage tank, and a flexible duct portion having a flexible portion inlet end and a flexible portion outlet end. The inlet end of the duct is adjustably supported by the second end of the support arm. The flexible portion outlet end engages the inlet end of the duct in fluid communication, and is bendable both up/down and sideways and is expandable in length between the flexible portion inlet end and the flexible portion outlet end.
