MIL-HDBK-1005/7A
Section 6:
TREATMENT
6.1
Guidance and Methods
6.1.1
Guidance. At permanent and temporary installations,
disinfection by chlorination, chloramination, or other means
will be applied to all water for potable uses, except from
municipal or private water supply sources which conform to the
bacteriological criteria set forth in Section 3. Refer to CFR
40 for additional treatment beyond disinfection.
6.1.1.1
Field Bases. Disinfection should be applied to all
water before use. Additional treatment should be provided to
naturally contaminated water. Special decontamination treatment
should be applied to chemically contaminated water in addition
to regular treatment.
6.1.2
Related Criteria. For design criteria of boiler feed
water and power plant water supplies in central heating and
power plants, refer to Water Conditioning in the MIL-HDBK-1003
Series on Mechanical Engineering.
6.1.3
Methods . Factors affecting the selection of treatment
methods include: quality of water supply source, quality of
desired finished water, dependability of process equipment, ease
of operation, flexibility in reacting to changing water quality,
space for construction, generation of wastes, and capital and
operating costs. Refer to Water Quality and Treatment, Chapter
3, "Guide to Selection of Water Treatment Processes," AWWA,
Fourth Edition. Table 3.1, "General Effectiveness of Water
Treatment Processes for Contaminant Removal," provides the
effectiveness of treatment processes such as aeration and
stripping, coagulation, sedimentation, filtration, lime
softening, ion exchange, membranes, disinfection for primary
contaminates (microbial, turbidity, inorganic, organic), and
secondary contaminants.
6.1.3.1
Application of Chemicals.
Refer to pars. 6.7, 6.8,
and 6.12 for chemicals to be used.
6.1.3.2
Pilot Study. For all permanent installations where
water is to be handled by processes not adequately tested in
nearby plants, operating on a similar water supply, a pilot
study should be conducted to determine both the efficiency and
arrangement of proposed treatment used.
