초록 ▼

A fluid purification system has cells whose purifying capability can be regenerated. Some of the cells are arranged in series to reach a high level of purification. An automatic valve network is controlled to cycle the cells in a way that levels the loads on each, thereby maximizing the service interval for replacing expired cells, enabling all of the cells to be replaced at the same time after having each contributing approximately equally to the purification load, and operated such that at any one time, at least one cell is regenerated so as to enable continuous up-time.

대표청구항 ▼

1. A method of purifying water, comprising: flowing water from a source along a flow path defined by automatic valves through a plurality of electronic deionization cells in a series, each of the cells having an inlet that receives input water and an outlet that outputs filtered water when flow through the cell is in a forward direction, a first cell encountered by the water in the series having a lowest rank in the series, the rank increasing along the series, and a last cell encountered by the water in the series having a highest rank in the series; andperiodically changing a configuration of the flow path by controlling the automatic valves by a controller, whereina first portion of the water that has passed through all cells except the cell having the highest rank is collected as purified water,a second portion of said water that has passed through all cells except the cell having the highest rank flows through the cell having the highest rank in a reverse direction, opposite of the forward direction, to regenerate said cell having the highest rank, andsaid periodically changing the configuration of the flow path includes switching the automatic valves such that in a changed flow path configuration the cell having the lowest rank becomes the cell having the highest rank that receives water in the reverse direction and a rank of each other cell decrements to a next lower rank, respectively. 2. The method of claim 1, further comprising: repeating the periodically changing the configuration. 3. The method of claim 1, further comprising: repeating the flowing the water from the source and the periodically changing the configuration of the flow path multiple times so that each cell takes more than one turn at each rank and is regenerated substantially an equal number of times. 4. The method of claim 3, wherein each cell contains more than one water purification module arranged in series or in parallel. 5. A method of purifying fluid, comprising: using a controller and a fluid management system, directing the fluid serially through a plurality of cells, each cell of the plurality of cells having a single flow path through which said fluid flows and trapping impurities present in the fluid flowing along said single flow path to purify the fluid in multiple stages while regenerating at least one cell of the plurality of cells such that fluid is purified continuously by cells other than said one cell of the plurality of cells without interruption for the regenerating; andusing the controller and fluid management system, changing flow paths of the fluid management system so that the directing and regenerating are effective to subject each cell of the plurality of cells to an equal filtering load so that each cell is exhausted at the same time, after being subjected to multiple instances of said regenerating, wherein the fluid is water and the cells are electronic deionization cells. 6. The method of claim 5, wherein the changing of the flow paths includes flowing fluid in a reverse direction through a respective cell during said regenerating and flowing fluid in a forward direction through respective cells during said directing.
