Liquid Filtration Testing - Well Developed Science or Abused Art Form?
At its best liquid filtration testing is a well developed science. At its worst it is a misunderstood and often abused art form. On September 23-25, 2008 at the Charlotte Hilton University Place in Charlotte, NC, the American Filtration and Separations Society (AFS) will be holding its' fall conference on "Infrastructure, Sustainability & Testing Management." One full track, 8 sessions & 32 presentations, will be devoted to Filter Testing. The conference is preceded by a day of filtration short courses on September 22 at the same location, including a half-day course on Liquid Filtration Testing.
Minneapolis, MN (PRWEB) September 4, 2008 -- At its best liquid filtration testing is a well developed science. At its worst it is a misunderstood and often abused art form. In the USA alone industry spends tens of millions of dollars each year performing filter characterization testing. This includes laboratory bench top methods for early stage process research or validation of vendor performance claims as well as in field scaled down physical pilot testing. With all this testing you would think there would be true consensus on best practices and methods but that is not always the case.
It is not uncommon to hear filter experts say the only way to "really" know if the intended filter meets the proposed process requirements is to do physical in plant testing. Their reason being that in some cases there are too many variables and unknowns to perform a meaningful lab scale bench test. And while that is sometimes correct when processes are under defined, it is expensive, puts the plant in a non production mode, and unless the process is stable can too offer misinformation. The same can hold true for standardized industry laboratory tests if it is difficult to exactly duplicate field conditions in the laboratory.
To minimize the effects of misinterpretation, and misinformation standardized international testing methods have been developed where well defined and completely controlled process parameters can be achieved. International test methods are developed, by multinational teams of experts who collaborate to establish stable, repeatable and well accepted testing protocol.
Filter testing for fuel, water, and lube oil used in automotive, aerospace, nuclear, waste water and drinking water industries are widely used and accepted. These include tests for: Permeability, Porosity, Bubble point, Porometry Tests, Particle Counting, Dirt Holding Capacity (DHC), Efficiency rating, Beta Ratio, LRV, Collapse Tests, Cyclic Testing, Water Removal Efficiency, Single Pass Filter Testing, Differential Pressure Testing, Multi-Pass Filter Testing, Dead End, Side Stream, Cross Flow, Diafiltration, Sub Micron Efficiency Tests.
So whether it is best to perform laboratory tests or scaled down in-field pilot tests is never simple. Often the best approach is a balanced mix of both. Working together smartly; process engineers, field operators and testing scientists can achieve meaningful results.
On September 23-25, 2008 at the Charlotte Hilton University Place in Charlotte, NC, the American Filtration and Separations Society (AFS) will be holding its' fall conference on "Infrastructure, Sustainability & Testing Management."
One full track, 8 sessions & 32 presentations, will be devoted to Filter Testing. The conference is preceded by a day of filtration short courses on September 22 at the same location, including a half-day course on Liquid FiltrationTesting.
The Liquid Filtration Testing short course is offered on Monday, September 22, 2008, 1 pm - 4 pm. The course will cover filter testing techniques and standards for water, fuel, lube oil, hydraulic fluids and other industrial liquids. In addition particle characteristics and efficiency methods and ratings will be reviewed.
AFS is the premier organization in North America dedicated to R&D, problem solutions and technology transfer in filtration and separation for the benefit of industrial processes, individual health and a clean environment.
