International Filter Testing Services, Inc. USA

IFTS wished to develop an experimental method to define and quantify the cake adhesion to the filtration cloth and to study the parameters influencing it. A bad cake discharge can lead to a decline in productivity and yield losses.

The device used for cake adhesion to filtration cloths.

In order to measure this, a prototype was designed and built, and has already measured the strength between a cake and filter cloth.

The system measures the breakout forces and fracture energies of cakes. The first results showed good repeatability with shear stress.

The development and new methods used to quantify cake adhesion to filter media will be one of the topics discussed at the IFTS Conference, which will be held in Lyon, France on October 16th.

Dr. Marie Andrée Sirvain joined the IFTS team in 1986 and serves as the Head of the Training Center and Technology Surveys.

As a PhD Research Engineer, she performs a myriad of roles. Her responsibilities include: continuous training, feasibility studies, writing the monthly company newsletter, and managing the technical databases. 

 

"Filtration, Solid-Liquid Separations and Membrane Separations are used in every industrial sector, "  Dr. Sirvain comments on working at IFTS. "This allows us to meet people who are very diverse and varied; it is very rewarding." 

 

Marie studied Industrial Chemistry at the Institute of National Applied Sciences and then earned a Chemical Engineering Doctorate at the University of Sciences in Toulouse.
