The nuclear industry is advancing by leaps and bounds and has made outstanding contributions to the economic construction of human society. At the same time, a large amount of radioactive waste is also produced. Among radioactive wastes, especially radioactive wastewater accounts for a major part. The large volume of wastewater, the large storage area and the large amount of radioactive substances have become the focus of radioactive waste treatment.

The treatment methods of radioactive wastewater mainly include precipitation, ion exchange, adsorption, biological treatment, membrane treatment and evaporation concentration. Among them, the evaporation concentration method is the most widely used, and the volume reduction ratio is large, and it often treats complex water quality. However, the evaporation concentration method has high energy consumption and large investment, and has great resistance to further promotion. Therefore, it is necessary to develop a process for the treatment of radioactive saline wastewater, which has achieved the purpose of recovering radioactive solids and discharging wastewater up to the standard. However, because radioactive wastewater contains a large amount of radioactive substances,
Moreover, there is also a high concentration of sodium nitrate. A little improper sealing during the processing process will cause the discharge of radioactive substances to cause harm to animals and plants. In view of this harsh environment, how to treat radioactive wastewater simply, efficiently and safely, and more importantly, low energy consumption, low investment, and targeted design of applicable devices to meet the needs of practical applications is what people hope.
HH side-mounted online density meter zero calibration
1) When the measuring range of the density meter is 0-1g/cm, the zero calibration can be operated according to the zero adjustment diagram. But make sure that the bubble of the level on the meter is in the center of the red circle, and there is no medium in the tube
3) When the measuring range of the density meter is 1-2g/cm, the zero position can be operated according to the zero position adjustment diagram. But make sure that the bubble of the level gauge on the meter is in the center of the red circle, and the tube must be filled with a density of 1g/cm. cm of purified water.

HH side-mounted online density meter range adjustment
The pipeline is filled with standard liquid corresponding to the range. During the heating process of the pipeline, the displayed density value will change, because the temperature of each part of the entire density meter system is inconsistent. Input after the temperature of each part of the system is stable. (Because the operation is more complicated, improper operation may directly affect the use of the instrument, if it must be adjusted, please call us)
