Configuration of monitoring apparatus for small and medium-sized water treatment of the present invention Configuration of a water treatment system using a monitoring device for small and medium-sized water treatment of the present invention

  FIG. 2 shows a configuration of a water treatment system using a monitoring device for small and medium-sized water treatment of the present invention.

During normal operation, the raw water obtained from the water source 3 such as a well is supplied from the chemical tank 2 through the chemical feed pipe 21 when the raw water obtained from the water source 3 such as a well is fed through the raw water feed pipe 31 according to the command of the water treatment command device 6. To the water treatment unit 4 having filtration and catalytic functions. Finished water treated with chemicals and catalyst and filtered is stored in the finished water tank 5 through the finished water feed pipe 7 and supplied to the intended use.
The finished water is supplied to the monitoring device 1 by the finished water supply pipe 7 and is divided into the finished water supply pipe 71 and the finished water supply pipe 71.

  Due to chemical depletion, fluctuations in raw water quality, pump failure, and overflow of product precipitates, the finished water may become contaminated abnormally finished water.

FIG. 1 shows the configuration of the monitoring device 1. The monitoring device 1 includes a monitoring device detection unit 11 and a monitoring device control unit 12.
Light emitted from the light emitting unit 1212 of the photoelectric switch 121 is sent to the monitoring device detection unit 11 through the optical fiber attachment end 113 by the optical fiber 1213, passes through the test water 1111, and is monitored from the optical fiber attachment end 114 through the optical fiber 1214. The process returns to the light receiving unit 1211 of the photoelectric switch 121 in the apparatus control unit 12.
Whether or not the test water 1111 of the monitoring device detector 11 is contaminated is detected by the intensity of the received light energy.

  In the monitoring device detection unit 11, the test water is supplied from the test water inlet 111, passes through the test water flow path 1121 built in the monitoring device detection unit 11, and is discharged from the test water discharge port 112.

  The contamination of the test water is determined by comparing the energy of the returning light with the set value at the light receiving unit 1211 of the photoelectric switch 121. This function is a basic function of the photoelectric switch 121. When the value is lower than the set value, the photoelectric switch 121 is activated as pollution, and generates an alarm signal indicating the pollution.

  The determination of the contamination is performed by selecting the contamination signal by extending the monitoring time by the timer 122. The activation of the photoelectric switch 121 due to abnormally finished water is indistinguishable from the passage of bubbles and dust that are the cause of the expected false alarm. However, these false alarming factors have a short duration, and those due to abnormally finished water have a long duration, so they can be distinguished in most cases by extending the monitoring time.

  The pollution signal detected and selected as described above can be transmitted to a necessary place from the monitoring device controller 12 as an abnormality alarm.

In order to reduce costs, efforts are being made to obtain inexpensive irrigation water with a quality equivalent to that of clean water.
The finished treated water cannot be monitored by personnel to reduce the price of water. Inexpensive monitoring devices are not commercially available. For this reason, customers who use large amounts of water due to abnormally finished water use tap water. Also, it is operating without monitoring where there is little loss due to abnormally finished water.
If the quality and reliability of the finished water are improved by the monitoring device 1, the market of water treatment devices will expand, and if inexpensive water can be used, it will lead to industrial competitiveness.
