“…This equation agrees with a filtration model given by Tiller and Cooper [14], Carmen-Kozeny's equation for average specific resistance (α), and an equation by Happel and Brenner [15] for Kozeny's constant. The Happel and Brenner model and Carmen-Kozeny equation both determine specific resistance but assume the domain is made up of either unit cells or bundles of parallel tubes.…”

ACKNOWLEDGMENTSThis first part of EM-31 project WP-2.3.6 dealt with determining ways to improve crossflow filtration operations at both the DOE Savannah River Site and the DOE Hanford Site. It included both a literature review and experimentation. The authors would like to thank the SCUREF intern student, Caroline E. Johnson, for assisting in both tasks. Compiling and reviewing references, interviewing filtration researchers, and writing a summary of the background material was very useful to plan experimentation. Furthermore, Ms. Johnson's initial experimental work with the included dead-end filtration tests was invaluable to proceed with the subsequential crossflow filter tests.As always, experiments cannot be performed in the Engineering Development Laboratory (EDL) without the assistance of many experienced engineers and specialists. Tim Steeper helped design the filter housings and his engineering input to the overall facility design was very important, Jerry Corbett created the necessary drawings for the flow system and Mike Restivo was very helpful with his knowledge on the valves and electrical equipment, Mike Williams assistance was very important to complete the Hazards Analysis Package paperwork and with the simulant development. Support from Jeff Smoland to analyze the safety aspects of project and his assistance to coordinate all the many individuals to complete the HAP is greatly appreciated. Advice and insight from John Steimke on all aspects of filter operation as well as that of the EDL manager, Bill Giddings, kept the work fundamentally sound.The crossflow filter tests, which were performed in the EDL could not have been realized with assistance of the laboratory's experienced personnel. Doug Sumpter's technical staff and his planning were fundamental to the successful operation of the experiment. Vernon Bush did a great job with setting up the data acquisition system. We were lucky to have Jimmy Mills perform the instrument calibrations before his retirement in December 2010; we wish him well. Andy Foreman did a great job to support Mike Armstrong when he was unavailable. We are especial grateful to Mr. Armstrong (The Doc) for modifying the existing filtration equipment, operating the test facility, and efficiently address the many problems as they occurred.

“…Although the filter cake generally exhibits compressible behavior in which α av varies with the applied filtration pressure, it should be noted that Eq. (15) is applicable to not only the incompressible cake but also compressible cake (Tiller and Cooper, 1960;Tiller and Shirato, 1964). Differentiating Eq.…”

Blocking filtration laws consist of four different filtration mechanisms: complete blocking, standard blocking, intermediate blocking, and cake filtration. Blocking filtration laws for describing both the pore blocking and cake formation have been extensively employed over the past several decades to evaluate the increase in filtration resistance with the progress of filtration in the field of classical particulate filtration. In recent years, blocking filtration laws become widely used also in membrane filtration such as microfiltration and ultrafiltration of colloids. This paper gives an overview of the developments of blocking filtration laws and equations under constant pressure and constant rate conditions reported for the filtrate flow of Newtonian and non-Newtonian fluids. The fouling index evaluating the degree of membrane fouling was examined on the basis of the blocking filtration equations. The blocking filtration laws were reexamined to extend the range of their application. Moreover, various combined models developed based on the blocking filtration laws were introduced for describing more rigorously the complicated filtration behaviors controlled by more than one mechanism which occurs successively or simultaneously.

“…(9)Ҁ(11). Thus, the variation of the mass fraction c of the solid in the filter cake with the distance x from the medium surface can be also calculated from the result of e versus w. For a practical standpoint, the following empirical functions of p s may be convenient for simplified evaluations of filtration characteristic values [12,13].…”

It is extremely important from both theoretical and industrial viewpoints to develop simple and precise filtration test methods. The most commonly used tests are classified into three groups: vacuum filtration tests, pressure filtration tests, and compression-permeability tests. Such overall filtration characteristics as the average specific filtration resistance α av and the average ratio m of wet to dry cake mass are mea- Eiji Iritani
