Nano flat ceramic membrane wastewater treatment technology and integrated equipment

Nano flat ceramic membrane wastewater treatment technology and integrated equipment combine nano flat ceramic membrane separation technology and sewage biological treatment technology to form nano flat membrane wastewater treatment technology and integrated equipment, optimize the key application parameters of technical equipment, and achieve efficient treatment of wastewater. The ceramic film used in the equipment has the advantages of high strength, acid and alkali resistance, corrosion resistance, long service life, high integration and automation level of equipment, flexible and convenient operation, stable and efficient, and can be controlled remotely.

The technology and equipment are suitable for sewage treatment in the fields of urban domestic sewage treatment, industrial sewage treatment, rural domestic sewage treatment, livestock and poultry breeding and slaughtering.

Ceramic membranes, also known as inorganic ceramic membranes, are asymmetric membranes made of inorganic ceramic materials by special processes. Inorganic ceramics such as aluminium oxide, zirconia, titanium oxide and silicon oxide with different specifications are mainly used as supports, which are prepared by surface coating and high temperature sintering. Commercial ceramic membranes usually have three layers of structure with asymmetric distribution. The filtering accuracy covers microfiltration, ultrafiltration and nanofiltration. Compared with traditional organic membranes, ceramic membranes have excellent properties such as high temperature resistance, acid and alkali resistance and high mechanical strength, and have become one of the membrane materials with rapid development and great application prospects in the field of membranes. However, besides being widely used in the field of water treatment in Japan, high cost has always been a bottleneck in the commercialization of ceramic membranes.

In recent years, with the development of manufacturing scale economy, the life cycle cost of ceramic membranes has gradually reached the zero point of growth. It has become an important trend in this field to further reduce costs while maintaining high performance. The performance and technical index of inorganic membrane components in our country have reached the level of similar products abroad. With the maturity of ceramic membrane production process and the reduction of cost, a large number of ceramic membranes will be applied in wastewater treatment, reclaimed water reuse and other fields which can only use organic membranes, and their application prospects are broad.
