Patent ID: 8920140

Claim:
A system for purification of water, the system comprising: a pump unit configured to generate sufficient pressure to process fluid through a reverse osmosis unit at a desired rate; the pump unit comprising: a pump; a shroud extending over at least a portion of an outside circumferential edge of the pump, wherein the shroud comprises channels configured for through-flow of a process fluid; wherein the pump is configured for through-flow of the process fluid to cool the pump; and a pump controller configured to receive power from at least one solar panel, the pump controller further configured to control the pump by regulating power from the at least one solar panel to the pump, wherein the pump controller is thermally connected to a pump controller radiator, the pump controller radiator comprising channels configured for through-flow of the process fluid, wherein the pump controller radiator transfers heat from the pump controller to the process fluid; wherein the shroud and the pump controller radiator are configured to heat the process fluid in order to decrease the pressure differential required to move the process fluid across a reverse osmosis membrane of the reverse osmosis unit to purify the process fluid.
