cuss issues such as purpose of the project, authorization, project description, and the
economic factors influencing the design choices. The design requirements and provi-
sions will discuss general parameters, which may affect the project design, functional
and technical requirements, design objectives, design calculations, and coordination
with the installation or outside agencies for civil, architectural, structural, mechanical,
electrical, and fire safety design components. The O&M section will address user O&M
responsibilities and O&M enhancement and cost reduction.
Introduction. Filter design calculations apply design criteria to size equip-
ment, to edit guide specifications, and to develop construction drawings. Based on the
preliminary selection of equipment, additional calculations can also be done to deter-
mine parameters such as utility requirements, and supporting mechanical and electrical
requirements. Design examples illustrating the use of several of these calculations are
presented as appendices to this document.
8-3.1.1 An assortment of data sources is available to use as the basis of the design
calculations. Typical data sources include pre-engineering reports and treatability stud-
ies, standard reference materials, and other sources, such as telephone conversations
with manufacturers. Any source of data or basis used for the design calculations should
be identified and referenced appropriately in the design analysis.
8-3.1.2 Pre-engineered designs are typically used as the basis of the design calcula-
tions. For applications where package filters will be used, treatability studies may not be
practicable or necessary. Each data source used should be clearly identified within the
design calculation and properly referenced with the date, title, or other pertinent infor-
mation that will identify the data source and its validity.
8-3.1.3 Data and information from reference materials, other than data from pre-engi-
neering reports and treatability studies, can also be used for filter design calculations.
Reference materials consist of applicable codes, standards, textbooks, standard tables,
