2022-03-02 16:07

Nowadays, the use of porous ceramic technology to carry out in-depth treatment of water and gas to improve the degree of cleanliness has become a fairly mainstream method.
In the field of water treatment, whether it is the treatment of urban sewage or industrial wastewater, or the purification of groundwater such as well water into domestic water or drinking water, ceramic membranes are widely used in various environmental projects by virtue of their excellent adsorption and environmental compatibility. A good application effect has been obtained. Ceramic membranes are mainly divided into three types: plate type, tubular type and multi-channel type. Among them, the hollow plate type ceramic membrane ranks first in the application of ceramic membranes due to its large filtration area, good chemical stability, acid and alkali resistance, and strong anti-microbial ability.

The application of flat ceramic membrane group in sewage treatment project


Hollow plate ceramic membrane is mainly based on the theory of "physical sieving", according to within a certain range of membrane pore size, the permeability of the permeable material is different with different molecular diameters, so as to achieve the nanofiltration effect. The transmission performance of ceramic membranes is closely related to its microstructure, such as pore size and distribution, pore morphology, porosity and connectivity, etc. After testing, flat ceramic membranes have a pore size of 0.05-1um. Virus filtration can reach more than 99%. At present, the application of hollow plate ceramic membrane modules in MBR (Membrane Bioreactor) has been highly valued in the field of environmental protection. Compared with many traditional biological water treatment processes, the plate ceramic membrane MBR treatment system occupies more than 50% of the area. , only a small amount of excess sludge is produced, the effluent quality can reach the standard of reclaimed water reuse, and the process operation is simplified and the reliability is high.

In the building materials, metallurgy, chemical and other industries, the high-temperature flue gas and dust emitted by production will also cause serious pollution to the environment. In order to reduce the emission of harmful dust, porous ceramic filter material has become one of the main means of purifying high-temperature flue gas. It can pass through inertial collision, interception, diffusion, screening, electrostatic effect, electrostatic effect, etc. Various mechanisms such as gravitational settling and adhesion effects filter high-temperature dust-laden gases. However, with the increasingly strict environmental protection requirements, the traditional process cannot meet the new environmental protection emission requirements. Therefore, the high-temperature dust-nitrogen integrated honeycomb ceramic membrane filter element tailored for high-temperature dust-laden gas came into being. With its ultra-high filtration area, Excellent thermal shock resistance, ultra-thin filtration path, and high temperature dust and nitrate integrated honeycomb ceramic membrane filter element are obviously more handy in high temperature flue gas dust removal.

High temperature dust and nitrate integrated honeycomb ceramic membrane filter element


Whether it is a hollow plate ceramic membrane or a high temperature dust and nitrate integrated honeycomb ceramic membrane filter element, both of them are actually the flagship products of Jiangxi Boxin Jingtao Environmental Protection Technology Co., Ltd. As a fine ceramics enterprise rooted in the field of environmental protection for nearly 20 years, Jiangxi Boxin has deep experience in industrial organic waste gas treatment, domestic sewage treatment, industrial wastewater treatment, and oily wastewater treatment.
If you want to have an in-depth exchange with Jiangxi Boxin on the application of porous ceramics in the field of environmental protection, there is a good opportunity now. At the "2019 'Industrial Ceramics City' Innovation and Development Forum" held on June 17-19, general manager Wu Hanyang, the founder of Jiangxi Boxin, will bring us a presentation entitled "Hollow plate ceramic membrane and ceramic filter element in the Applications in the Environmental Protection Field" report. In addition to discussing the structure, performance and application problems of the hollow plate ceramic membrane and the problems to be solved in the future, the high temperature dust and nitrate integrated honeycomb ceramic membrane filter element and its application are also the focus of the report. do not miss it!
