In the field of sewage treatment and water resources reuse, MBR, also known as membrane bio reactor, is a new water treatment technology combined with membrane separation unit and biological treatment unit.Membrane bio reactor (MBR) is a new type of wastewater treatment system with the organic combi

compare the water quality after using plate ceramic filtration membrane.

Many membrane separation processes are based on different separation principles or mechanisms. The separated substances can range from particles to molecules. Despite such great differences, all membrane processes have one thing in common, that is, they need to be applied to membranes.

In the food industry, especially in the drinking wine industry, ceramic membrane technology needs to provide a full set of technical solutions, which need to be improved in the following aspects: first, the packaging process of ceramic membrane needs to be optimized, and seals, adhesives, pipes and valve ports need to be improved into food grade products. Secondly, the selective separation membrane module should be developed, and the appropriate filtration precision should be selected to effectively intercept the precipitates in the degree reduction process, while retaining the aroma substances in the wine body.

In 2021, World Oceans Day identified the theme as "life and livelihoods". June 8, 2021 is the 13th World Oceans Day and the 14th National Ocean Publicity Day. The theme of this year's Ocean Day is "protection of marine biodiversity and harmonious coexistence between man and nature". Biodiversity inc
