A system and method for cleaning, rinsing, and sanitizing a container is disclosed. The system has a sanitizing agent chamber for storing a sanitizing agent, the one or more solution chambers in fluid communication with the container, a pump in fluid commination with the sanitizing agent, wherein the pump is in communication with a gas, and at least one spray nozzle fluidly connected to the at least one solution chamber via a conduit positioned within the container, wherein the spray nozzle comprises a housing inside which the sanitizing agent is mixed at pressure with the gas to disperse the sanitizing agent and gas mixture into the container for sanitizing the container.

A retractable cleaning nozzle for spray cleaning an interior surface of a pipe or a tank includes a nozzle housing configured to be stationary mounted in a hole of the side wall of the pipe or tank and having a front side arranged to face towards the interior of the pipe or tank and a rear side arranged to face away from the interior of the pipe or tank, an inlet port configured for receiving a cleaning fluid, and a cylindrical interior bore with a central axis defining an axial direction, wherein the interior bore is open towards the front side of the nozzle housing. The cleaning nozzle includes a first plug movably arranged in the axial direction within the bore of the nozzle housing between a retracted position and a protruding position, wherein the first plug has a sleeve-shaped body with a front wall closing a front portion of the sleeve-shaped body, wherein the front wall of the sleeve-shaped body includes a first set of spray holes configured to eject cleaning fluid substantially in the axial direction, wherein the sleeve-shaped body of the first plug includes a second set of spray holes configured to eject cleaning fluid substantially in a radial direction perpendicular to the axial direction, wherein a front surface of the first plug is substantially flush with a front surface of the nozzle housing in the retracted position of the first plug, and wherein a front portion of the first plug, including the first and second set of spay holes, protrudes beyond the front surface of the nozzle housing in the protruding position of the first plug for enabling spray cleaning of the interior surface of the pipe or tank. The cleaning nozzle includes a second plug arranged within a space defined by the sleeve-shaped body of the first plug and configured for closing a flow path from the inlet port to the first set of holes of the first plug when the first plug is located in the retracted position.

A method of cleaning a submerged surface covered by a liquid medium includes injecting a cleaning liquid with a submerged fluid jet through the liquid medium at the submerged surface. The method may also include introducing at least one of a non-reactive gas and a reactive gas with the cleaning liquid through the submerged fluid jet.

This invention provides a method and a system for cleaning a container for storing wafers or masks. A contained with lid is washed directly after the container is loaded with lid opened in the cleaning system. Gas exchange rate in the washing station can be increased such that particles or AMC inside the container or attached to the lid can be carried out more easily. Then, contamination-free gas is purged to the container as well as lid in a high temperature environment. A vacuum station can be optionally adapted between the washing station and the contamination-free gas purging station to enhance the cleanliness of the container.

A method of cleaning a concrete bowl is provided including the steps of a) introducing water into at least one concrete bowl; b) collecting the water from the bowl after it has been used; and c) cleaning a concrete bowl by introducing at least some of the collected water into the bowl under pressure.
