Columnar Ceramic Membranes

Jiuwu high-packed columnar ceramic membrane is an inorganic ultrafiltration membrane for water treatment developed on the basis of Jiuwu's traditional tubular ceramic membrane and flat ceramic membrane. The high-packed columnar ceramic membrane is made of high-strength a-Al2O3 and fired at high temperature. It has good high temperature resistance, chemical corrosion resistance, and excellent mechanical strength. Compared with the traditional multi-channel tubular ceramic membrane, the filtration area of a single membrane tube with a high-packed column ceramic membrane can reach 10-25 square meters, with greater packing density and processing capacity, which can effectively remove suspended solids, bacteria and colloids, etc. It can be used in many fields such as civil safe water, municipal water supply and wastewater treatment, emergency water supply, water reuse, industrial process wastewater, etc.

• The support body is made of inorganic ceramic material, which is durable and has a long service life
• The single-membrane column has large area, high packing density, high flux and high water production
• Better chemical resistance, wide range of chemical cleaning conditions
• The channel of membrane element is 2~4nm, with stronger SS tolerance and stronger backwash effect
• Adopting a proprietary flow channel design, the water in and out of the water channel is well distributed, and the operating efficiency is improved
• High mechanical strength, high pressure filtration and backwashing
• Influent water quality requirements are low, resistance to influent water quality fluctuations
• The pore size distribution of the membrane layer is narrow, and it is a multi-layer structure, which is more anti-pollution and easy to clean
