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.

Apparatus for treating a surface of a wind turbine blade (14), comprising an expandable structure (22) that is deployable from a collapsed state into an expanded state in which the structure defines an elongated treatment zone (32) into which a blade (14) is receivable in use. The apparatus includes treating means (52) arranged to apply a treatment in the treatment zone. Also provided is a method for treating a wind turbine blade (14) including: positioning a wind turbine blade in a substantially vertical orientation; locating an expandable structure (22) adjacent the wind turbine blade; deploying the expandable structure (22) about the blade (14) such that the expandable structure (22) defines an elongated treatment zone (32) which receives at least part of the blade (14); and applying surface treatment to the surface of the blade (14) using the expandable structure (22).

The substrate processing apparatus includes common piping which guides a processing liquid to a branching portion, supply piping which guides the processing liquid from the branching portion to a chemical liquid nozzle, return piping which guides the processing liquid from the branching portion, and a discharge valve which changes a flow rate of the processing liquid supplied from the common piping to the branching portion. The discharge valve makes a valve element stationary at a plurality of positions including a discharge execution position at which the processing liquid is supplied from the common piping to the branching portion at a flow rate larger than a maximum value of a suction flow rate and a discharge stop position at which the processing liquid is supplied from the common piping to the branching portion at a flow rate smaller than the maximum value of the suction flow rate.

A system and method of cleaning an aircraft APU entails positioning an elevated platform beneath the APU compartment, suspending a curtain from the doors of the APU compartment, positioning a basin beneath the curtain, attaching the curtain to the basin and pressure washing the APU or a portion thereof with steam and/or hot water. Runoff collected in the basin is transferred to a storage container for industrial wastewater treatment.

A method and system for monitoring goods placed in compartments of an inventory apparatus and communicating monitored data to user-computing device via a communication network. The method includes storing information pertaining to goods into a database. The method further includes integrating weighing scales at the bottom of each of the one or more compartment. Further, the method includes determining the weight of the one or more goods in each of the one or more compartment through the weighing scales and transmitting the weighed information to the database via the communication network. The method further includes the monitoring the quantitative value and inventory level of one or more goods placed in the one or more compartments through one or more sensors. Furthermore, the method includes the displaying the weighed information and monitored information over the user-computing device communicated through the communication network.

A cleaning device arranged in a table which is driven. The cleaning device includes one or more cleaning through holes provided in the table and opened at positions facing a workpiece or a jig, a container unit provided in the table and including a storage space which receives cleaning fluid; a movable member that is arranged in the container unit, that defines the storage space, and that is supported movably in a direction intersecting a horizontal axis line; and a cleaning piping component connecting the storage space and the cleaning through holes.

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.

A container for receiving and transporting residual washout concrete or cement from concrete handling apparatus comprising a rectangular top frame member including two lateral top frame members and two transverse top frame members, the top frame members affixed at their distal ends thereby forming the rectangular top frame member, and a rectangular bottom frame member including two lateral bottom frame members and two transverse bottom frame members, the bottom frame members affixed at their distal ends thereby forming the rectangular bottom frame member, wherein the top and bottom frame members are oriented in substantial parallel planes, and including rigid side frame members affixed to both the top frame member and the bottom frame member, thereby maintaining the substantial parallel relationship between the top and bottom frame members, further including side plate members affixed to the side frame members, and a bottom plate member affixed to the bottom frame members, the side and bottom plate members together with the top, bottom, and side frame members forming a concrete or cement tight container.

A system for recovering antifreeze from a dust prevention system of a mineral material processing plant, wherein the system includes an antifreeze tank, a pump configured to circulate water and/or antifreeze, a first valve configured to connect to a water inlet and/or antifreeze tank to the pump, a nozzle manifold connected to the pump, a second valve configured to connect the nozzle manifold to the antifreeze tank and/or a third valve, and a control system. The control system is configured to operate the system according to a method including the steps of sucking water using a pump from a water inlet via a first valve, displacing the antifreeze via a nozzle manifold into an antifreeze tank until the water reaches a second valve, and connecting the second valve to a third valve to allow circulation of water in the system.
