<br />RFP 24-057 <br /> <br />587-0702 <br /> <br />B. System: Special equipment warranty will be for 10 years from final acceptance of <br />the project and will provide for repair and/or complete replacement of the blowers, <br />duct work, scrubber structure or vessel, electrical wiring, and controls in the event <br />of corrosion damage, including equipment, materials, labor, and any and all costs <br />associated with repair or replacement. <br /> <br />C. Media: Special equipment warranty will be for 10 years from final acceptance of <br />the project and will provide for complete replacement of the media, including <br />equipment, materials, labor, and any and all costs associated with washing, <br />replacing or regenerating the media as needed. Media failure includes increase in <br />pressure drop through the media such that the specified airflow rates are not <br />achievable with the installed equipment and/or the failure of the media to meet <br />specified odorant removal levels. <br /> <br />PART 2 - PRODUCTS <br /> <br />2.01 PERFORMANCE AND DESIGN REQUIREMENTS <br /> <br />A. Source Characteristics <br /> <br />1. <br /> <br />Wastewater Treatment Plant: <br />This odor control unit will treat foul air from the WWTP headworks, primary <br />clarifiers, and solids handling facilities. The CITY is currently in the process <br />of defining what the ultimate solids handling facilities will encompass. For <br />the purposes of this RFP, the PROPONENT will assume that foul air from <br />the solids handling facility will include air from sludge holding tanks and an <br />expanded sludge dewatering facility using centrifuges and an enclosed truck <br />loading bay. The final determination for the solids handling facility will be <br />made prior to requesting the final and best offer. <br /> <br />The following table will be used as a preliminary basis for process design <br />and selection. A proposal will be submitted for treating three different <br />airflows as indicated in the table. This information will be updated during the <br />negotiation process, if necessary. <br /> <br />I <br /> <br />I <br /> <br />Foul Air Source Totals <br />Foul Air Flow, cfm 21,000 25,000 30,000 <br />Inlet Hydrogen Sulfide 5-50 5-50 5-50 <br />Concentration Ran es, m <br />Inlet Ammonia 0-150 0-150 0-150 <br />Concentration, Ran es m <br />Other inlet odorants Reduced Reduced Reduced <br /> Sulfides, Sulfides, Sulfides, <br /> Amines, Amines Amines <br />Ambient Air Temperature 0-120 0-120 0-120 I <br />OF <br /> <br />11065-7 <br />
