Abstract

The present invention provides a remote monitoring system for monitoring the operation of a fluid treatment system and/or the qualities, characteristics, properties, etc., of the fluid being processed or treated by the fluid treatment system. The system includes a remote computer that may be associated with a database that accesses data transmitted from the fluid treatment system with the data collected, acquired, etc., from one or more sensors placed in the fluid treatment system for measuring fluid quality and/or equipment operation in a fluid treatment system. The remote computer may then analyze or manipulate the data to generate an analysis result or analysis report that may be sent or communicated along with the data and/or any historical or expected information or data to a remote viewing device for viewing by a user. A method is further provided for the operation of the remote monitoring system of the present invention.

Claims

1. An apparatus for monitoring a status and operation of a fluid treatment core facility, the apparatus comprising:

one or more sensors positioned within the fluid treatment core facility;

the one or more sensors being configured to gather data relating to;

fluid conditions within the fluid treatment core facility,

operating parameters of the fluid treatment core facility, and

performance of a reverse osmosis membrane positioned within the fluid treatment core facility;

the one or more sensor being further configured to transmit the gathered data;

an analyzer configured to;

receive the gathered data from the one or more sensors,

evaluate the gathered data, and

generate a report based on the evaluated data;

a computer processing device disposed outside of the fluid treatment core facility and configured to;

monitor the fluid treatment core facility, and

transmit a result of the monitoring to a recipient;

the computer processing device including a processor and a software program stored in a memory of the computer processing device, the computer processing device including a plurality of instruction interpretable by the processor such that the software program causes the computer processing device to perform the monitoring and to transmit the result of the monitoring; and

a viewing device including a display, the viewing device positioned outside the fluid treatment core facility and configured to receive the result of the monitoring and display the result of the monitoring,

wherein the monitoring includes;

receiving at the analyzer the gathered data from the one or more sensors; and

analyzing the data received from the one or more sensors using the analyzer,

wherein the transmitting and displaying of the result of monitoring includes;

transmitting the report generated by the analyzer to the viewing device positioned outside the fluid treatment core facility using a communication device; and

displaying, at the display of the viewing device, the report in a color-coded format that allows the recipient to visually evaluate the status and operation of the fluid treatment core facility,

the color coded display including a display of information indicating;

the fluid conditions in the fluid treatment core facility, the fluid conditions including information regarding the quality of the fluid within the fluid treatment core facility,

an alarm condition indicating potential harmful fluid conditions in the fluid treatment core facility,

a condition of the reverse osmosis membrane,

a regulatory compliance requirement, and

a predicted maintenance requirement;

the predicted maintenance requirement being determined by the analyzer based on a current state of the fluid treatment core facility and a historical record of a previous state of the fluid treatment core facility,

wherein the analyzer is in communication with or is located on the computer processing device.

2. The apparatus of claim 1, wherein the computer processing device comprises at least one of the following:

a computer, a cell phone, a handheld device, an Internet or web server, a database, or an ftp server.

3. The apparatus of claim 1, wherein the one or more sensors are configured to detect or measure at least one of the following:

fluid temperature, chemical composition including total organic carbon (TOC), fluid quantity, flow rate, waste products, contaminants, conductivity, pH, pressure, turbidity, permeate flow, chlorine concentration, fluorine concentration, tank levels, equipment status, and equipment operation.

4. The apparatus of claim 1, wherein the analyzer comprises source code or a software program.

5. The apparatus of claim 1, wherein the analyzer is configured to generate the report based on expected data.

6. The apparatus of claim 1, wherein the analyzer is configured to manipulate the gathered data in at least one of the following ways:

continuously, in real time, at periodic intervals, at selected intervals, on condition, and on demand by a user.

7. The apparatus of claim 1, wherein the report includes an alarm.

8. The apparatus of claim 1, wherein the viewing device is at least one of the following:

personal computer, personal terminal, web server, Internet server, file transfer protocol (ftp) server, cell phone, pager, and handheld device.

9. The apparatus of claim 1, wherein the report is sent or uploaded to the viewing device in at least one of the following ways:

continuously, in real time, at periodic intervals, at selected intervals, on condition, and on demand by a user.

10. The apparatus of claim 1, wherein the communication device is at least one of the following:

Internet, facsimile, file transfer protocol (ftp), voice messaging, text messaging, text to voice messages, electronic mail, pager, human voice calling, SMS messages, instant messaging, groupware protocols, public switched telephone network, cellular network, wireless communication, satellite communication, and radio communication.

11. The apparatus of claim 1, further comprising a database for storing the data received from the one or more sensors, wherein the database is part of the computer processing device or is in communication with the computer processing device.

12. The apparatus of claim 1, wherein the report comprises an analysis result.

13. The apparatus of claim 1, wherein the report is sent or uploaded to the viewing device continuously.

14. The apparatus of claim 1, wherein the report is sent or uploaded to the viewing device in real time.

15. The apparatus of claim 1, wherein the color-coded graph includes a pie chart.

16. The apparatus of claim 1, wherein the color-coded graph includes a bar graph.

17. The apparatus of claim 1, wherein the color-coded graph includes an indication by color of normal or abnormal operations.

18. The apparatus of claim 1, wherein the display further includes displaying the evaluated data in geographical layout in order to pinpoint the origin or cause of a problem within the fluid treatment core facility.
