MIL-HDBK-1005/16
a)
Eliminate nonessential floor drains in maintenance
bays by plugging them.
b)
Implement oil use and recovery plans.
c)
For spill cleanup, use dry absorbents and dispose
of as solid waste.
d)
If necessary, route drains through an oil/water
separator prior to discharge to the sanitary sewer.
e)
Segregate waste streams and recover wastes where
possible.
f)
Where approved, implement the use of nonpersistent
emulsifying degreasers, which should help minimize emulsified
oils. In addition, substitute degreasers with hot water/high-
pressure washers where applicable. Consider end-use of pressure
washer (aircraft, vehicle) to determine maximum allowable
pressure.
g)
Where significant quantities of suspended solids
are expected, provide pretreatment to remove suspended solids.
h)
In some cases, washrack wastewater reuse may be an
option and should be considered.
3.2.3.2
Additional Resources. Proper design and operation of
oil/water separators is essential to the successful handling of
wastewaters from vehicle and aircraft maintenance and wash
facilities. Further information on oily wastewaters and the
design of oil/water separators is included in Section 5 of this
handbook, in MIL-HDBK-1005/9, and in MIL-HDBK-1138, Wastewater
Treatment System Operations and Maintenance Augmenting Handbook.
Additional information on wastewater discharges and
treatment for tactical vehicle wash facilities is included in TM
5-814-9, Central Vehicle Wash Facilities.
3.2.3.3
Closed-Loop Recycling. Closed-loop recycling may be
another option to manage wastewater from vehicle and aircraft
maintenance and wash facilities. There are advantages and
disadvantages associated with closed loop recycling systems.
