This issue will focus on Combination Filtration with Mechanical Slurry Conditioning to improve trouble shooting and process optimization. 
The updated technical article also includes data showing the possible improvements with this approach

Welcome to the Third Year of A&SoF. We trust that all of our readers had a safe and healthy holiday season and we wish everyone a successful 2012.  A&SoF is an e-newsletter, managed by BHS, with its sole purpose to enhance the filtration knowledge of the marketplace to solve actual plant problems.
 

Last year A&SoF introduced a new approach to solving process problems called “Combination Filtration.”   This approach relies upon the slurry analysis and testing to uncover the “process symptom” and then develop a process solution called “combination mechanical slurry conditioning and filtration.”  It differs from the traditional approach of using coagulants and flocculants to change the particle characteristics for improved filtration.  
 
The first paper, abstracted below, is written by a good friend of mine, Jose Sentmanat.  Jose and I met as competitors in the 1989 Chem Show and we have become good friends.  His 48 years’ experience, greater than my 30, provides for excellent insights into liquid filtration and leads directly into Combination Filtration.  The second updated paper discusses techniques for actual batch or continuous mechanical slurry conditioning followed by process filtration and contains data showing the results.  
  

Finally, BHS-Filtration Inc. and A&SoF is growing again.  Please see the process engineering opportunity described below.

Clarifying Liquid Filtration - A Practical Guide
 
Sentmanat, J.M. Chemical Engineering, Pages 38-47, October 2011

In this article, Jose Sentmanat discusses laboratory testing and then follows into a discussion of filtration systems such as basket filters, filter–presses, horizontal leaf filters, tubular filters, pressure leaf filters, belt filters and nutsche filters.  He continues by reviewing the mechanisms of filtration including precoat, body feed and filter cleaning. The article concludes with trouble shooting and preventive maintenance programs.  This is an excellent article for a process engineer who is looking to improve their understanding of filtration.  My congratulations to Jose on a very informative and well written article; he can be reached at www.filterconsultant.com.  
 
 
There is a new definition of combination filtration that transcends the standard approach and will assist process engineers with trouble shooting and “idea-generation.”  The approach relies upon the slurry analysis and testing to uncover the “process symptom” and then develop a process solution called “combination mechanical slurry conditioning and filtration.”  
  
This article discusses slurry testing and process analysis and then illustrates case history example installations showing “combination mechanical slurry conditioning and filtration.” The article has been updated with actual data showing the benefits of this approach.  Read the full process solution provided by BHS.
