MIL-HDBK-1027/1B
(1)
Determine the required level of wastewater
treatment.
(2) Determine applicable regulations necessary to
obtain the wastewater permit.
(3) Determine the necessity of additional
environmental studies of the projected wastewater (if required)
to identify:
(a)
BOD - biological oxygen demand
(b)
COD - chemical oxygen demand
(c)
pH
(d)
TSS - total suspended solids
(e)
TDS - total dissolved solids
(f)
Priority pollutant scans
(g)
EPA priority pollutant scans
b) The effluent is not toxic as the high COD could
imply and is completely biodegradable when combined with
acclimated bacteria. Surfactant quantities in excess of
200 mg/kg should require the addition of an anti-foaming agent
to suppress foaming. A typical anti-foaming agent is Betz No.
300 defoamer.
c) Firefighting trainer wastewater should always
require secondary treatment before being discharged to the
environment because of high BOD and COD.
d) Provisions for onsite biological treatment should
be provided where the receiving stream does not include
secondary treatment. At those sites where Navy owned secondary
treatment will be required, the design should consider the
effect of precipitate on the treatment process. High surfactant
effluent generates a precipitate so it may be desirable to
reduce the precipitate in the biological section by flocculating
and sedimentation prior to treatment.
