MIL-HDBK-1005/9A
These require extensive equipment, time, and test procedures,
and do not provide a rapid assessment of effluent toxicity.
2.4.7.2
Rapid Bioassay Procedure (RBP). The use of RBP should
be considered by naval installations in lieu of standard
procedures. RBP is a useful tool in effluent monitoring since
inexpensive yet reliable toxicity data can be obtained quickly.
The EPA as an equivalent method has not approved RBP. Check
with a State regulatory agency for approval of RBP prior to
developing a test program.
A substantial database of toxicity of pure compounds,
and of raw and treated industrial effluents has been developed
using RBP (refer to Use of Rapid Bioassay Procedure for
Assessment of Industrial Wastewater Treatment Effectiveness,
presented at the 38th Purdue Industrial Waste Conference, May
1983). The RBP results have shown good reproducibility and
correlation with results of the long-term standard procedure.
The RBP is best conducted using one of the proprietary methods
and equipment available from chemical instrumentation and
equipment manufacturers (for example, the Beckman MicrotoxTM
system, Beckman Instruments, Inc.).

Wastewater Collection
2.5.1
Gravity and Pressure Systems. Primary considerations
in collecting industrial wastes are waste segregation and
material selection. Protect pipes, pumps, and appurtenances
coming in contact with the wastewater from damage that can be
caused by solvents, corrosion, temperature, and pH
characteristics of the wastes. Double-wall pipe with leak
detection may be required in some application where potentials
for soil contamination exist. Collection system modifications
or pretreatment steps should be considered for industrial wastes
with high solids or sludge content or for wastes that may react
to produce solids and sludge deposits. Address the release and
formation of toxic or explosive gases in the system design. The
following limitations on discharge to industrial waste sewers
should be observed.
2.5.1.1
Storm Water. Storm water should not be carried in
industrial waste sewers. Provide separate industrial and storm
water collection systems.
