Storage. See Table 21 for space criteria and Table 22
for type criteria. Refer to American Concrete Institute (ACI),
Concrete Sanitary Engineering Structures, for criteria on
protection of concrete against chemicals.
a) Store materials in original containers in dry
rooms on boards or pallets.
b) Locate storage for dry chemicals at the level of
feed hopper inlets if possible.
c)
Do not exceed safe floor load limits.
d) For liquefied gas cylinders, provide cool, dry,
well ventilated, aboveground storage rooms of noncombustible
construction, remote from heat sources, walkways, elevators,
stairways, and ventilating system intakes.
e) Determine compatibility of all chemicals stored.
Store incompatible chemicals separately.
f)
Refer to paragraph 4.7.2.5 for personnel safety
precautions.
4.7.2.3
On-Site Generation and Feeding Equipment
a) Ozone.
Ozone can be generated from air or from
high-purity oxygen.
(1) Generation from air requires the air to be
filtered and dried to a dew point less than -58F (-50C) by
desiccation and refrigeration.
(2) When using oxygen for the production of ozone,
refrigeration and desiccation are not required except when
recycling is used. Use oxygen for the generation of ozone where
savings are indicated. Power consumption is halved when oxygen
is used to generate ozone, but oxygen must be recycled or used
for aeration to achieve overall economy.
