Ceramic membranes have long since been regarded for their specific advantages in separation techniques, notably chemical and thermal stability, high flux rates, and potential for regeneration. Made with an α-Al2O3 support layer, the intermediate layers and the membrane are made of TiO2 or ZrO2 depending on pore size. 

Such features have led to use in a growing range of applications, particularly in applications involving concentrated caustics and acids. 

Interested in exploring the ceramic membrane technology for filtration? 

inopor® Ceramic Membrane Test Kits are now available at Sterlitech. Each kit includes:

• Choice of 3 Single Channel Membranes MF - NF

What is the purpose of spacers and shims used with the membrane test cells, and do I need them?

Crossflow velocity (CFV) refers to the linear rate of flow of the feed solution as it passes tangentially over the surface of the membrane filter and is measured in meters or feet per second. Some of the feed solution will permeate through the membrane filter, while the balance will flow along the surface of the membrane and collect as concentrate that can be recirculated through the system. The crossflow velocity has a direct impact on the fouling rate and the occurrence of concentration polarization — where a concentration gradient forms in the fluid adjacent to the membrane surface.

To calculate crossflow velocity (CFV) you will need to divide the volumetric flow rate of the feed solution in the flow channel by the cross-sectional area

Oktoberfest is an annual beer festival held over the course of two weeks during September-October in Munich, Germany. Its origins date back to October 12, 1810, when the festival was first held to celebrate the marriage of Prince Louis of Bavaria, who later became King, to Princess Therese von Sachsen-Hildburghausen. Over the years, the festival has evolved to include an amusement park and fun-fair, food and drink stalls, and several large and lively beer halls, where much of the merry-making takes place.

The Oktoberfest is a huge attraction for both locals and tourists alike. More than six million revelers attend Oktoberfest each year, consuming more than 2 million gallons of beer during the two week event.
