Radioactive sewage treatment

Radioactive sewage treatment of radioactive waste water is extremely harmful to the environment. We have been engaged in the research and treatment of such industrial wastewater since the early stage of nuclear industry development, holding patents and obtaining engineering applications. Radioactive elements such as uranium , radium and cobalt in wastewater can be thoroughly removed to meet the national radioactive requirements for external drainage. The technology and equipment used are at the leading level in the world. At the same time, the technology to remove radioactivity can also be used in water supply systems.

This series of calender is applied to all kinds of paper and paperboard's follow-up calendaring and finishing. When paper web passes through pressure area of each calender roll, it will be influenced by combined effect of pressure between rolls and surface friction, which plays a key role for improving smoothess, glossiness, tightness, stiffness and other physical indexes of paper and paperboard.
