FIELD TESTS AND INSPECTIONS
**************************************************************************
NOTE: These tests are required for installed or
completed work; they are different and separate from
those required for materials and products prior to
installation or application. Delete tests not
applicable or required.
Provide in this section a reference to the plant
commissioning or start-up specification which
includes the processes in the treatment facility.
**************************************************************************
Accessories such as the [UV equipment,] [ozone generator,] [compressor,]
[ozone generator gas feed equipment,] and [_____] shall be factory tested
prior to shipment to the job site.
3.10.1
AOP Reactor Vessel
The AOP reactor vessel and attached appurtenances shall be assembled at the
factory and an operational test of all components accomplished prior to
shipment. Certification that the equipment and components assembled at the
factory are operational and meet the specification requirements shall be
provided to the Contracting Officer a minimum of [10] [_____] calendar days
prior to shipment. Components not assembled at the factory shall be
subject to the same tests and inspections prior to onsite leak testing
using potable water. Following installation at the project site, and prior
to leak testing, the AOP system shall be retested to ensure the equipment
and auxiliary components act as a complete and operational system. This
shall include operation of all valves, pumps, blowers, analyzers, alarms,
meters, interlocks, monitors, level and pump controls, sensors, switches,
off gas destruct equipment and all other equipment associated with the AOP
system. Testing shall be completed prior to leak testing and written
notification provided to the Contracting Officer stating the equipment is
working in accordance with the contract documents and manufacturer's
recommendations prior to the commencement of leak testing.
3.10.2
Diffuser or Injector System
The entire gas piping system shall be pressure tested with dry air or
oxygen at a minimum of [two] [_____] times the normal design pressure for a
minimum of 60 minutes and such additional time as required for the
Contractor to inspect the piping system for leaks. All leaks shall be
repaired and the system shall be retested until no leakage is detected.
Ozone shall not be introduced into the system until all leaks have been
identified, repaired, and the system retested. [Diffusers] [Injectors]
shall be installed in accordance with the suppliers recommendations. After
installation, the [diffusers] [injectors] shall be covered with clear water
to a depth of approximately [1] [_____] m [3] [_____] feet. Dry air or
oxygen shall be released through the [diffusers] [injectors] and the system
shall be inspected for uniform air or oxygen distribution throughout the
reactors. Following the initial testing at [1] [_____] m[3] [_____] feet,
the distribution testing shall be repeated at a water depth of [3] [_____]
m [9] [_____] feet to ensure bubble distribution is adequate throughout the
