The Application of Ceramic Membrane in High Salt Wastewater Treatment

The membrane industry has played an irreplaceable supporting role in solving water resource shortage, air and water environment pollution, developing new energy industry, especially through process industry reengineering, improving energy and resource utilization, and reducing environmental pollutant emissions. In many years of exploration and practice, membrane technology is also constantly repairing new problems, solving new challenges, and achieving breakthroughs and innovations.

The circulating sewage has high salt content, high hardness, and is complex and changeable. Even the incoming water of the same project in different periods is constantly changing, which has become a difficult point for the industry. The ceramic membrane has strong impact resistance, and is especially suitable for water treatment with large changes in incoming water. Even if the turbidity of raw water suddenly increases, the ceramic membrane system can continue to operate stably.

The different from the conventional treatment process of high salt water in the market (adding acid directly after alkali softening), in the ceramic membrane treatment process, high salt water is softened, filtered by the ceramic membrane device, and then added with acid, and sand filtration is omitted.

NanoMem ceramic membrane has the characteristics of good chemical stability, acid resistance, alkali resistance, organic solvent resistance, high mechanical strength, reverse flushing, strong anti microbial ability, high temperature resistance, narrow pore size distribution, high separation efficiency, etc. It has been widely used in food industry, bioengineering, environmental engineering, chemical industry, petrochemical industry, metallurgical industry and other fields.
