Monitoring deviation timely reminding technology of reverse osmosis nanofiltration system

Abstract

The invention relates to a monitoring deviation timely reminding technology of a reverse osmosis nanofiltration system. The technology comprises an electric conductivity meter, the reverse osmosis nanofiltration system, a water producing electric conductivity meter, a water inlet flow rate meter, a concentrated water electric conductivity meter and a concentrated water flow rate meter. Through theaddition of the concentrated water electric conductivity meter, the Y2 correction recovery rate can be obtained. Through the comparison between the Y1 system recovery rate and the Y2 correction recovery rate, the system P deviation value is obtained. By setting the system P deviation value, the reminding is timely performed when the condition that any one parameter value of the system exceeds therange is judged. By setting the system P deviation value, the reminding is timely performed when the condition that any one parameter value of the system exceeds the range is judged. The system Y2 correction recovery rate is obtained by using the electric conductivity parameter but not limited to the electric conductivity parameter; the system Y2 correction recovery rate can also be obtained by using parameters of a certain substance, such as chloride ions, sodium ions and potassium ions in the system or the TDS value.

Description

technical field [0001] The patent of the invention belongs to the technical field of water treatment, especially in the technical field of reverse osmosis nanofiltration membrane system application. Background technique [0002] After the development of reverse osmosis nanofiltration technology in recent years, the technology is becoming more and more mature, but the reverse osmosis nanofiltration membrane system often has instrument detection deviation, inaccurate monitoring, untimely calibration and many other problems in engineering examples, which may affect the system operation status. Misjudgment, often misevaluating the system by misjudging people and misleading people. [0003] At present, almost all monitoring instruments of reverse osmosis nanofiltration systems include feed water conductivity meters, product water conductivity meters, product water flow meters, and concentrated water flow meters. + Concentrated water flow meter value) * 100%" to get the recovery ...

AI Technical Summary

Problems solved by technology

[0004] At present, the values ​​monitored by many conductivity meters and flow meters on the market after a period of time often have a certain deviation from the actual values, and the meters need to be calibrated regularly. If the calibration is not timely, it will often lead to misjudgments and errors by system operators or managers. guide
