Model 14 - Modular Carbon Adsorpti

Making Water and Air Safer and Cleaner www.calgoncarbon.comPRODUCT BULLETINDescriptionThe Calgon Carbon MODEL 14 is an adsorption vessel designed forthe removal of dissolved organic contaminants, including disinfectionbyproducts (DBP) or natural organic matter (NOM) from liquids usinggranular activated carbon (GAC). The vessel is sized to hold 60,000pounds of GAC which provides the additional contact time required toremove either compounds at low concentrations or poorly adsorbingcompounds. The standard design is a single vessel concept where anumber of MODEL 14 vessels are configured for parallel operation.As an option, two vessels can be combined with a centralized pipemanifold to allow for series operation. This flexibility of configurationsallows the engineer to select the alternative that best meets the requirements of the site and treatment objectives.The MODEL 14 vessel is provided with one (1) GAC fill line and three(3) GAC discharge lines. The multiple discharge lines are positionedto each extract 20,000 pounds of spent carbon. This feature minimizes the time required for GAC exchanges by eliminating theguesswork of loading the spent to the trailers. The two (2) sidemounted discharge nozzles are provided with stainless steel insertsthat have two functions. The stainless nozzles project into the vesseland protect the lining during carbon exchange. Also, GAC can vary indensity depending on starting material and activity. The discharge nozzle inserts can be rotated 360 degrees to accommodate the differing densities. If the nozzle insert wears away it is designed tobe easily replaced. The design has the benefit of Calgon Carbon's extensive expertise and has been proven in numerous applications.The engineering package can be provided quickly and the system expedited through Calgon Carbon's production capabilities.The MODEL 14 is provided with three (3) in-bed sample assemblieswhich allows the operator to monitor the progress of the adsorbentas it flows through the bed.All valves and accessories are located at low elevations for ease ofoperation and maintenance.The MODEL 14 is designed with a unique internal cone under-drainthat provides for the efficient collection of treated water and the distribution of backwash water. Also, the internal cone ensures efficientand complete discharge of spent carbon from the adsorber withoutthe need to open the manway to manually wash out the residual spent carbon.The MODEL 14 system is designed for use with Calgon Carbon'sclosed loop carbon exchange service. Using specially designed carbon transport trailers, the spent carbon can be removed from theadsorber via a pressurized carbon-water slurry; and fresh carbon refilled in the same manner. This closed loop transfer is accomplishedwithout exposure of personnel to either spent or fresh carbon. CalgonCarbon can also manage the disposition of the spent carbon. It canbe returned to Calgon Carbon for reactivation; avoiding the need forthe site to arrange for disposal.Carbon Adsorbers• Carbon Steel ASME code pressure vessels• Internal vinyl ester lining (nominal 35 to 45 mil dft where GACcontacts steel) for potable water and most liquid applications• Polypropylene slotted nozzles for water collection and backwash distributionStandard Adsorption System Piping• Full bore stainless steel ball valves for GAC fill and discharge• PPL lined steel pipe for GAC discharge• 4?

In closedor partially closed containers and vessels, oxygen depletion may reachhazardous levels. If workers are to enter a vessel containing carbon,appropriate sampling and work procedures for potentially low oxygenspaces should be followed, including all applicable federal and staterequirements.
