Принадлежит: TROJAN TECHNOLOGIES

There is described a fluid treatment system that is particularly well suited for treating ballast water on a shipping vessel. The present fluid treatment system is characterized by having two general modes of operation. A so-called ballasting mode and a so-called deballasting mode. In the ballasting mode, water is pumped from the sea or other body of water in which the shipping vessel is located to a ballast fluid inlet in the present fluid treatment system. Thereafter, it passes through the filter separation and radiation treatment sections in the fluid treatment zone of the fluid treatment system. Next, the fluid exits the fluid outlet of the fluid treatment system and it is pumped to one or more ballast tanks that are located on the shipping vessel. In the deballasting mode, water contained in the ballast tank(s) is pumped to a deballasting fluid inlet of the fluid treatment system after which it is treated in the radiation section only—i.e., in the deballasting mode, water substantially bypasses the fluid separation section of the fluid treatment system. Next, the treated fluid exits the fluid outlet of the fluid treatment system and is discharged overboard the shipping vessel. A valve system is used to switch between ballasting mode and deballasting mode. 1.

Agricultural implements are used to transport material, such as inputs in the form of fertilizer, seed, treatment, or some combination thereof, to row units that apply the material to an area of a field. Metering systems can aid in metering and providing a desired amount of material, such as on-demand, to the row units. The metering systems move the metered material to the row units, such as with pneumatics or other fluids.

The secondary container 24, inside which are the primary containers 34 holding the liquid 35, is sealed from the atmosphere by an insulating cover 32. The closed space 38, between the inner hull 14 and the secondary container 24 is also sealed from the atmosphere and may be divided into several compartments. In order to detect leakage through the insulating container wall 24, the closed space 38 (or each compartment of the closed space) is connected to the insulated space 31 through the four way valve 48 and the pump 42, which produces a pressure differential between the two spaces. Any leak in wall 24 can be detected by observation of flowmeter 54 or pressure indicator 56. With valve 48 in the position shown, space 38 would be at a greater pressure than space 31 and leakage of gas from the secondary container would be stopped. With valve 48 in another position, space 38 would be at a lower pressure than space 31, which would encourage the cold gas to escape. The position of the leak would then be found by observing the localised formation of ice on inner hull 14. As an alternative, the pump may be replaced by a source of compressed inert gas, e.g. compressed nitrogen bottles.
