A spillage containment system is provided. The spillage containment system is designed to receive heavy equipment, e.g., for stowage, and to catch and contain any liquid or other debris that the heavy equipment may leak (e.g., oil or other environmentally harmful chemicals). The system includes a base large enough to receive the heavy equipment, and left, right, and back side walls. The system also includes a front drive-over device including an upward ramp opposing a downward ramp. The heavy equipment may drive over the drive-over device to be placed on the base. The drive-over device, and the left, right, and back sidewalls define a sealed inner volume within which the heavy equipment may be stowed.

A grout cleaning device is disclosed herein. The device comprises a cover, a connector configured on an operative top surface of the for facilitating secure connection of a pressurized water dispenser thereon. There is also an adaptor attachable to the connector for being in fluid communication with the pressurized water dispenser. The adaptor is configured for directing a jet of water from the pressurized water dispenser on a grout slit requiring cleaning. Additionally, there is a suction attachment disposed within an interior space defined by the cover for sucking a slurry of dirt and water resulting from the cleaning of the grout slit.

A system for and method of removing residues, deposits, and debris from a substrate that has been marked by a chemical etching process is disclosed. The system includes one or more upper sprayers that deposit a cleaning solution to a top surface of the product as it passes beneath the one or more upper sprayers. The system further includes at least one upper brush that operates to scrub the top surface of the product after the cleaning solution has been applied thereto. The system optionally includes one or more lower sprayers and lower brushes to clean a bottom surface of the product as it is conveyed through the system. The system further includes an air knife system that assists with drying the product prior to exiting the system. The system further includes a controller that is operable to adjust various system parameters.

A wash hood for a baffle-type grease filter and a pollution control system for cleaning baffle-type grease filters outside or inside without contaminating the environment or soaking the operator with cleaning solution. The hood includes ridges on the inside for supporting the filters at an angle to a rear wall. A channel around the ridges guides the effluent towards a drain hole. A separator box with a filter connected to the drain hole separates the grease from the water such that the water may be discharged into a mop sink connected to a sanitary sewer system.

A liquid cleaning system for living plants rests on a surface covered by a non-porous material. A plate layer covering the non-porous layer has two or more layers, each layer having runners arranged in a grid. The grid of each successive layer is offset at an angle with respect to the grid of a previous layer. An upper layer covers the plate layer and has a plurality of holes for the passage of liquids into the liquid cleaning system. As the living plants are watered or cleaned, excess liquids containing water and oils that were excreted by the living plants enter the liquid cleaning system through the holes, the liquid traverses the grid layers, flowing towards a drain. Contaminants within the liquid collect within the grid of the layers of the plate layer for later disposal.

A wastewater collection system of a water wash system includes a collection duct configured to attach to a gas turbine engine for receiving a mixture of air and wash liquid from the gas turbine engine during washing. The wastewater collection system additionally includes a separation assembly, the separation assembly including a shaft, one or more impellers mounted to the shaft, and a casing. The casing at least partially encloses the shaft and encloses the one or more impellers. The casing defines an inlet for fluidly connecting with the collection duct, an air outlet, and a liquid outlet. The air outlet is disposed opposite the one or more impellers from the inlet and the liquid outlet.

Contamination of a bottom surface of a substrate caused by a processing liquid used for cleaning a top surface of the substrate can be suppressed. After performing a liquid processing on the top surface of the substrate and a liquid processing on the bottom surface of the substrate in parallel while rotating the substrate by a substrate holding/rotating unit, when stopping the liquid processing on the top surface of the substrate and the liquid processing on the bottom surface of the substrate, a control unit 18 stops a supply of the processing liquid onto the top surface of the substrate by a first processing liquid supply device 73, and then, stops a supply of the processing liquid onto the bottom surface of the substrate by a second processing liquid supply device 71.

A containment apparatus, kit and method for containing liquid waste when cleaning a kitchen ventilation system wherein the containment apparatus includes a funnel that is removably attachable to an attachment device on a kitchen ventilation hood.

Vehicle washing apparatus has a platform for supporting a vehicle and a filtering grid covering the platform. A hopper under the grid receives a combination of water after its use in washing the vehicle and waste removed from the vehicle surface by the washing. Larger solid matter is retained on the grid. The fluid combination is pumped from the bottom of the hopper to a clarifier having another hopper. Another pump is used to pump bottom-lying residue from the other hopper into a separator bag formed of mesh material permitting drainage of water from the separator bag into the clarifier while maintaining solids within the separator bag.

An apparatus includes a wafer stage and a particle removing assembly. The wafer stage includes a cup adjacent to a wafer chuck. The particle removing assembly is configured to remove contaminant particles from the cup. In some embodiments, the particle removing assembly comprises a flexible ejecting member that includes one or more elongated tubes, a front tip, and a cleaning tip adapter configured to attach the front tip to each of the one or more elongated tubes. The front tip includes front openings and lateral openings from which pressurized cleaning material are introduced onto an unreachable area of the cup to remove the contaminant particles from the cup.
