PART 1 GENERAL

1.01 SCOPE

A. Provide four new (including twelve existing) for a total of 16 vapor phase granular activated carbon (VPGAC) adsorption roll-off units. The roll-off units will be configured as one new (including four existing) for a total of five trains, each with two adsorbers in series. Each of five trains shall serve as a complete once-through forced flow system removing VOCs from the exhaust of three air strippers (1 train each) and the aerated tanks/equipment exhaust (2 trains). The additional two new (including four existing) for a total of six adsorbers will serve as spares.

B. The lead bed shall be capable of reducing the levels of the listed organic contaminants to the values shown in Article Performance Requirements for the service life period listed in Article Performance Requirements. Each adsorber shall be filled with pelletized granular activated carbon for removal of organic contaminants from air stripping and emissions from other aerated tanks/equipment. Terminology is in conformance with ASTM D2652. The adsorbers shall be designed to operate continuously, 24 hours per day, 7 days per week.

C. The specified adsorbers are for installation of the first phase of the system. The Buyer may purchase, simultaneously, or in a later procurement, additional adsorbers for a future phase of installation.

D. The manufacturer shall provide an estimate for the adsorbers specified herein. However, the manufacturer may provide a second offering for alternative vapor phase activated carbon adsorption equipment that meets the functional and performance requirements specified.
