Calibration of analytical instruments should be taken seriously Each instrument should be calibrated before use
Step time to determine the current water control in the implementation of the operation or regeneration of water treatment, due to the lack of online testing means that each process step time required by repeated tests to determine the results obtained. Step time can be based on changes in the process of operation, through the host computer to modify.
Analysis of analytical instruments The analytical instrument is the visual nerve of the system, the calibration of analytical instruments should be taken seriously, each instrument should be verified before put into use. Whether the failure of the bed operation mainly depends on the measurement results of the analytical instruments. Before the operation and control system is put into operation, it is necessary to ensure that the measurement results are accurate and reliable. In addition, the bed operation failure, pay attention to close the sampling of the analysis instrument once the door to protect the instrument sensor from acid-base corrosion.
Analysis of the instrument signal output problems The operation of water treatment is random furnace to supplement the water demand may be, water treatment outage or regeneration, the flow of analytical instruments may occur within the flow of water, pollution and other phenomena, yang sodium table, anion bed conductivity Instrument detection signal and program control interlock, when the bed is put into operation again, it may lead to program-controlled malfunction or can not be started automatically.
