norweco,", <br /> SINGULRIR"' 910-KINETIC " <br /> WASTEWATER TREATMENT SYSTEM <br /> MODEL TNT <br /> GENERAL SPECIFICATIONS <br /> The contractor shall furnish and install one complete Singulair Bio-Kinetic Model TNT system for <br /> Total Nitrogen Treatment with all necessary parts and equipment as described in the following <br /> specifications. Treatment of the domestic wastewater shall be accomplished by the extended • <br /> aeration process with non-mechanical flow equalization,pretreatment of the influent and filtration <br /> of the final effluent. In addition to primary, secondary and tertiary treatment of the wastewater <br /> flow,the treatment system shall provide nitrification,denitrification,and if required, chlorination <br /> and dechlorination of the effluent prior to discharge. All treatment processes shall be contained <br /> within reinforced precast concrete tankage meeting the requirements of ACI Standard 318. The <br /> wastewater treatment system shall be a Singulair Model TNT as manufactured by Norweco, <br /> Inc., Norwalk, Ohio, USA. Systems utilizing fiberglass, steel, or plastic tankage are subject to <br /> flotation when dewatered and shall not be considered for this application. <br /> The wastewater treatment system shall be capable of reducing Total Nitrogen without the addition <br /> of chemicals, specialized add-on processes or additional components. Nitrification and <br /> denitrification shall be accomplished within the chambers of the treatment system prior to effluent <br /> disposal. Biological reduction of nitrogen shall occur naturally by autotrophic bacteria,capable <br /> of converting ammonium nitrogen to nitrate and heterotrophic bacteria,capable of transforming <br /> nitrate to harmless gas. The treatment system shall include precast concrete tankage providing <br /> separate pretreatment,aeration and clarification chambers. Principal items of electro-mechanical <br /> equipment shall be a 1725 RPM mechanical aerator, UL listed Service Pro control center with <br /> MCD technology, Bio-Static sludge return and Bio-Kinetic tertiary treatment device for flow <br /> equalization and final filtration of system effluent. <br />
