What Is a Ceramic Membrane?

Ceramic membranes are the most crucial part of a water filtration system, where the membranes are stored in a housing. Within this housing, liquid is filtered as the ceramic membranes filter fluids by removing, e.g., suspended solids, oil droplets, oil emulsions, particles, and bacteria. Ceramic membranes can purify liquids at different levels depending on the specific needs and requirements, which make ceramic membranes relevant for several task...

What Is a Ceramic Membrane Made Of?

The material silicon carbide is a synthetically produced crystalline compound containing pure silicon and pure carbon. Silicon carbide is the second hardest material in the world, exclusively exceeded by diamonds, and the hardest man-made material ever made. On Mohs Scale, which measures mineral hardness based on an ordinal scale ranging from 1-10, silicon carbide scores 9.5, while diamonds score 10. Due to silicon carbide's strength and durabili...

How Is a Ceramic Membrane Cleaned?

Regardless of what material a membrane is made of and which dimension it has, the main problem in membrane filtration processes is fouling. Therefore, cleaning is essential to reduce fouling issues and restore permeability and selectivity. Cleaning is typically performed with mechanical forces as a physical cleaning or with chemicals as a chemical cleaning. As feedwater is fed to the ceramic membranes, it is separated into permeate, which is filt...

What Kinds of Ceramic Membrane Support Designs Exist?

Global water consumption has almost six doubled since 1920. And it is still on the increase as a result of rapid population growth, advanced industrialization, and under the influence of climate changes. But with ceramic membranes, we can purify and recycle our scarce water resources. However, multiple types of ceramic membrane support exist, and it can be difficult to figure out their unique advantages, how they filter, and which membrane suppor...
