GENERAL. This UFC document will provide designers of HTRW treatment
systems a methodology for determining what filtration systems may be appropriate for a
specific application and for specifying a system that will meet the project needs. The
UFC is intended to address applications of less than 15 L/s (240 gpm) and is limited to
pre-packaged filtration systems available from various manufacturers.
Chapter 1 describes the purpose, applicability, allowable distribution, location
of reference sources, scope and background of the UFC.
This Chapter 2 describes how the document is to be used.
Chapter 3 describes the principles of filtration and filtration theory. This chap-
ter describes the purpose and mechanics of filtration so that the designer will have a
clear understanding of what functions are served. The chapter also discusses filtration
applications and where filtration fits within the overall treatment process. The chapter
describes various waste stream parameters that may influence the type and level of fil-
tration required. Finally, the chapter describes how pilot tests are used when specifying
Chapter 4 describes, in tabular form, how to screen and select processes. Us-
ing this table, the design professional will be able to narrow the range of potential filtra-
tion options to the one or two processes that are most likely to meet the needs of the
Chapter 5 describes in detail the various filtration processes. This chapter is
intended to allow the design professional to focus his or her attention on those proc-
esses that have been identified from Chapter 4.
Chapter 6 describes non-filtration components that should be taken into ac-
count as part of any filtration system design. These include disposal of residuals, pre-
treatment requirements, process control options, and operation and maintenance con-
Chapter 7 describes cost considerations that the engineer or design profes-
sional should take into account to ensure that all applicable costs associated with a par-
ticular filtration system are accounted for.
Chapter 8 describes items that should be included in any design package
developed for USACE HTRW applications.
