MIL-HDBK-1005/9A
2.6.1.3
Receiving Water. Present policy is to use an outside
contractor to haul difficult-to-treat wastes. In addition, deep
well injection may be used for low-volume, difficult-to-treat
industrial wastes if permitted by regulatory agencies.
Suitability of proposed substrata must be determined for each
specific case.
2.6.1.4
Sanitary Sewer. Avoid discharging industrial waste
materials that may damage the wastewater collection and
treatment facilities and/or cause potential personnel safety
problems (refer to paragraph 2.4.5 and WPCF MOP No. 3).
2.6.1.5
Batch Versus Continuous Treatment. Batch treatment is
preferable to continuous treatment of most industrial wastes
from Navy installations. Batch treatment requires more tankage
but allows greater process control than continuous treatment.
The extra capital investment in providing holding and process
tanks for batch treatment frequently offsets the cost of
controls and operation and maintenance requirements for a
continuous system. Batch treatment also provides additional
reliability since unusual discharge conditions on industrial
process lines are more easily accommodated. Use batch treatment
except for large flows where continuous treatment offers
significant advantages.
Design for flexibility in unit treatment processes and
total treatment systems. Provide interconnections within the
treatment facility to allow transfer of separated waste streams
to holding units or other treatment units. This will facilitate
treatment when separate collection systems are contaminated.
2.6.1.6
Disposal of Sludges
a) Process Selection. Sludge handling and disposal
operations must be evaluated concurrently with wastewater
treatment evaluations. Costs for sludge disposal can dictate
process selection for the wastewater treatment system. Refer to
MIL-HDBK-1005/8 for guidance on sludge processing operations.
Bench or pilot scale testing is recommended to establish design
parameters for industrial sludges.
