The unstable wastewater treatment processes and the consequent substandard effluent discharge are the long-term problems in coal mining industry. Since the stricter environmental policies are issued, the treated mine water is required to meet the requirement of Environmental Quality Standards for Surface Water (GB3838-2002).

SafBon has accumulated rich experiences in coal mine water treatment for many years. Now, SafBon introduces the world's advanced ItN nano-plate ceramic ultrafiltration membrane (CFM) technology into the existing mature pretreatment technologies, and applies them in the mine water treatment process upgrading and reconstruction projects. The CFM technology is mainly used for reducing COD, NH3-N and other heavy metal ions by removing the suspended solids (SS) and colloid in mine water. can be reduced. In results, the  effluent can stability meet the requirements of water quality Class III according to China’s Environmental quality standards for surface water.

The Integrated System of ItN CFM application in Mine Water Treatment

The excellent performances of ItN CFM in mine water treatment has attracted great attention from the experts of environmental protection bureau, design institute and university institute. The expert seminar of integrated equipment project for coal mine water treatment process renovations, which is  organized by the county environmental protection bureau of Shanxi, is held in August 11, 2017. In the seminar, dozens of environmental experts and leaders, who are from Shanxi provincial environmental protection department, Shanxi Luliang environmental protection department, Tongji University, Taiyuan municipal design institute, etc., agreed that the integrated CFM device had the various advantages, including high membrane flux, high effluent quality, high integration level, convenient operation, easy operation and maintenance, low costs and long service life. The experts also pointed out that the integrated CFM treatment device is a potential membrane treatment process and of great significance to improve the water quality of the treated coal mine water in the industry.

The Expert Seminar, Linxian, Shanxi Province（August 11th, 2017）

So far, the ItN CFM has been successfully applied in 8 mine water treatment projects, and the total treatment capability reaches 12000m3/d. The ItN CFM technology solves the long-term problems of mine water treatment in coal mining enterprises, and is widely praised in the industry!
