An apparatus for cleaning HVAC cooling coils comprises a supply and collection assembly having a housing defining an interior space for containing a quantity of cleaning solution. A pump has a pump inlet positioned to be in fluid communication with the cleaning solution and is operative to deliver the cleaning solution to a supply outlet of the supply and collection assembly. A vacuum source has a vacuum inlet positioned to be in fluid communication with an ullage space above the quantity of cleaning solution such that the vacuum source creates negative pressure in the ullage space during operation. A collection inlet is in fluid communication with the ullage space such that the cleaning solution is returned to the interior space through the collection inlet during operation of the vacuum source. A nozzle device is in fluid communication with the supply outlet via outlet piping so as to deliver the cleaning solution to a surface of an HVAC coil unit. A fluid return tool is in fluid communication with the collection inlet via return piping so as to collect used cleaning solution from the HVAC coil unit.

Effluent containment devices are made of flame-resistant material having a Flame Spread Index of greater than zero and less than 30. The material may also have anti-static properties, such as being formed of a dissipative material or one that resists flow electrification.

The present invention relates to a substrate treatment apparatus including: a substrate support assembly having a spin head adapted to seat a substrate thereonto; fluid supply unit for supplying fluid to the substrate; a bowl assembly having a plurality of bowls overlaid another outwardly in a radial direction thereof and surrounding the substrate support assembly; an ascending and descending unit for moving up and down the bowl assembly; and a chamber for accommodating the substrate support assembly, the fluid supply unit, the bowl assembly, and the ascending and descending unit, wherein the chamber is configured to have a plurality of process exhaust parts for performing exhaust from the inside of the bowl assembly and an environment exhaust part for performing exhaust from the outside of the bowl assembly.

A containment basin system includes a basin and a lifting brace configured to be secured to and stabilize the basin for lifting and emptying operations. The basin includes a bottom wall, three or more side walls, and a lip extending around a top of all of the side walls. The bottom wall includes two transverse recesses. The lifting brace includes a base, two guide rails extending perpendicularly from the base, and two receptacles extending perpendicularly from the base. The two receptacles of the lifting brace are configured to engage the two transverse recesses of the basin. Each of the receptacles includes a central space dimensioned to receive a fork of a fork lift. The two guide rails each includes an upper guide and a lower guide configured to receive the lip of the basin therebetween.

This disclosure relates to a system and method for handling effluent during a hydroblasting operation of a vessel. The system includes a bag assembly comprising a containment bag and a drain. A throat opening is configured to interface with an end of a vessel. The sidewall extends approximately longitudinally from the throat opening. The sleeve is located substantially circumferentially around the containment bag near the throat opening and is formed of a resilient, anti-static material.

A liquid cleaning and watering 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.

Provided is an apparatus for processing a substrate. The apparatus for processing a substrate includes a base portion configured to provide a rotational force in a circumferential direction; a holding module located on the base portion and configured to hold the substrate; a nozzle module located above the base portion and configured to jet a chemical liquid onto the substrate on the holding module; and a scattering prevention module located on the base portion at a peripheral portion of the holding module and configured to, when the chemical liquid is scattered after being jetted onto the substrate, guide the scattered chemical liquid to be discharged, wherein the scattering prevention module guides the scattered chemical liquid with a variable movement caused by the rotational force.

A portable pump and fuel containment system includes a portable base assembly including a lower support and wheels, a container on the lower support including an interior volume and inlet and outlet ports in fluid communication with the interior volume, and a liquid transfer assembly coupled to the portable base assembly. The liquid transfer assembly includes a pump, a three-way control valve, a flexible transfer line having a first transfer line segment coupled to a first inlet of the three-way control valve and a second transfer line segment extending from the outlet port to a second inlet of the three-way control valve, and a flexible return line having a first end coupled to the outlet of the pump and a second end detachably coupled to the inlet port of the container. An outlet of the three-way control valve is connected to an inlet of the pump.

Contained fluid application systems may be used to wash and disinfect large vehicles and equipment in extreme temperatures and remote locations. One system has a base having a platform, a washing station positioned on the base, an enclosure having an internal chamber, a conduit system connecting a fluid container to spray members, and a heating device that provides heat to the internal chamber and a duct system in the base. The system may recapture fluid and prevent freezing of fluid on the surface of the base while being able to apply washing and disinfecting fluid around the entire perimeter of a large vehicle or equipment in the washing station. The system is a unit that can be deployed rapidly and transported easily due to the unitary base and minimal amount of post-deployment assembly needed.

A cleaning device for removing contamination on a substrate holder used with an electroplating cell includes an arm, a cleaning agent supplier, a nozzle and a receiver. The cleaning agent supplier is coupled to the arm and configured to supply a cleaning agent. The nozzle is coupled to the cleaning agent supplier and configured to spray the cleaning agent onto the substrate holder to remove the contamination. The receiver is coupled to the arm and configured to receive the cleaning agent after the cleaning agent is sprayed onto the substrate holder.
