Section: claims

1. A system for reducing contaminant deposition on a surface immersed in a fluid, the system comprising:a fluid source including a pump configured to draw the fluid from a cavity in which the apparatus is immersed; andan apparatus configured to discharge a fluid from the fluid source against a surface while immersed in the fluid, wherein the apparatus includes the pump such that the pump is immersed in the fluid. 2. The system of claim 1, wherein the fluid is a coolant water, and wherein the apparatus is further configured to discharge the coolant water to create a flow speed of the coolant water immediately on the surface of at least 2 meters per second. 3. The system of claim 1, further comprising:a filter within at least one of the fluid source and the apparatus, wherein the filter is configured to remove contaminants from the fluid prior to discharge from the apparatus, wherein the filter includes at least one stage of resins to remove dissolved contaminants in the fluid. 4. The system of claim 3, wherein the fluid source includes,a heat exchanger to cool the fluid prior to discharge from the apparatus below a temperature of the fluid in which the surface is immersed; anda chemical injector configured to modify a chemistry of the fluid prior to discharge from the apparatus. 5. The system of claim 1, wherein,the fluid source includes a base having the pump, a first filter, and piping together configured to draw the fluid from the cavity in which the apparatus is immersed in the fluid,the apparatus is a mobile assembly including an induction pump connected to the fluid source, andthe mobile assembly is moveable within the fluid to discharge the fluid on several different positions on the surface. 6. The system of claim 5, wherein,the fluid source further includes a heat exchanger and a chemical injector,the mobile assembly includes an intake and a second filter together configured to draw the fluid from the cavity in which the mobile assembly is immersed in the fluid, andthe mobile assembly is moveable by force from the induction pump discharging the fluid within the cavity. 7. The system of claim 6, wherein the intake and the second filter are connected to the induction pump so that the fluid is actively drawn through the intake and the second filter is entrained with fluid from the fluid source to create the discharged fluid. 8. A mobile apparatus to reduce contaminant depositions by inducing flows in a space flooded with a liquid, the mobile apparatus comprising:a flow intake receiving the liquid from the space; anda multi-stage filter configured to filter particulate and dissolved contaminants from the liquid; andan outlet directing the liquid toward a surface so as to create a flow of the liquid having speed of at least 2 meters per second of the liquid contacting the surface, wherein the flow moves the mobile apparatus within the space. 9. The mobile apparatus of claim 8, further comprising:a pump connected to the flow intake, wherein the pump is configured to create the flow while the mobile apparatus is completely immersed in the liquid in the space. 10. The mobile apparatus of claim 9, further comprising:a liquid connection configured to receive liquid from a source, wherein the pump is an induction pump that drives the liquid from the source and the liquid from the intake together to create the flow. 11. The mobile apparatus of claim 10, wherein the liquid from the source has a different temperature, a different pH, and a different oxidizer content from the liquid from the intake. 12. The mobile apparatus of claim 8, wherein the multi-stage filter includes,a coarse reservoir stage,a fibrous filter stage,a charged bed stage,a metallic filtering bed stage, anda resin bed stage secured between two screens. 13. The mobile apparatus of claim 12, wherein each of the stages are in separate sections of the multi-stage filter, and wherein the separate sections are removably attached to each other through flanges on ends of each of the sections. 14. The mobile apparatus of claim 12, wherein the resin bed includes a resin configured to filter metallic solutes from the liquid that are removed from depositing on the surface. 15. A method of removing contaminant depositions on open-system surfaces immersed in a water bearing contaminants, the method comprising:flowing the water at a speed of about 2 meters per second where the water meets the surface, wherein the water includes an oxidizer and a weak acid when flowed at the surface, wherein the flowing is produced by a mobile assembly completely submerged in the water, wherein the mobile assembly includes an induction pump causing the flowing the water; andfiltering the water for contaminants dissolved in the water as a result of the flowing.
