specifications). This design and construction package can be used as a stand-alone or
integrated into an overall HTRW treatment plant design and construction package. The
paragraphs that follow provide a brief overview of the elements of the design analysis,
drawings, and guide specifications. In addition to the information provided below, a
description of general types of design calculations required is presented in Chapter 3
and a checklist of design documents and associated elements is presented in Chapter
4.
2-10.1
Design Analysis. The design analysis should be conducted in accordance
with ER 1110-345-700. For filter press applications, the design analyses should
include, but not be limited to, items such as:
2-10.1.1 A tabular summary or description, or both, of the characteristics of the
untreated sludge and desired sludge cake characteristics including:
2-10.1.1.1 Influent characteristics (i.e., flow rate, influent solids concentration, pertinent
chemical characteristics).
2-10.1.1.2 Conditioning requirements (i.e., chemical dosages).
2-10.1.1.3 Desired performance requirements (i.e., percent solids in sludge cake) and a
description of the methods used for disposal of waste streams.
2-10.1.2 A tabular summary and description of the filter press and the auxiliary sys-
tems used with the press (i.e., filter media washing systems) and supporting systems
(i.e., sludge feed systems, etc.). This information should include:
2-10.1.2.1 A brief description of each component and its relation to other components
within the dewatering system.
2-10.1.2.2 Number of each component required, type, designation (number), and size or
capacity.
2-10.1.2.3 Design demand and related design criteria (i.e., pressures, pumping
requirements, etc.).
2-10.1.3 A description of controls, instrumentation, and proposed operating sequence.
This description should not only address how the dewatering equipment will be inter-
faced within the dewatering system, but also should address how the dewatering sys-
tem is interfaced with the treatment processes that generate the sludge and other
related processes.
2-10.1.4 All calculations necessary to support the sludge generation capacity, equip-
ment sizing, and chemical dosages, for example.
2-10.1.5 Examples of manufacturer's literature for the supplied equipment.
