B -- HIGH-RATE DISINFECTION SOL RFQ-OH-97-00243 POC Ruby Sugg 513-366-2146 WEB: Office of Acquisition Management -- Cincinnati Contracts Management Division, http://www.epa.gov/oam/cinn_cmd. E-MAIL: Ruby Sugg, Cincinnati Contracts Management Division, sugg.ruby@epamail.epa.gov. The Urban Watershed Management Branch (UWMB) of the Water Supply and Water Resources Division (WSWRD) of EPA's National Risk Management Research Laboratory (NRMRL) is soliciting quotations on conducting a pilot-scale evaluation of an ultraviolet (UV)-generated chlorine dioxide high-rate disinfection technology for combined sewer overflow (CSO) or sanitary sewer overflow (SSO). In addition, the contractor shall provide recently collected information on several other new high-rate disinfection technologies such as: ozonation, chlorine dioxide, UV light irradiation, and high-voltage electron beam irradiation. A summary report that contains all information generated by the project shall be provided. The contractor/vendor shall have experience with high-rate and conventional disinfection technologies for CSO or SSO and be an active participant in a demonstration/evaluation effort of high-rate disinfection technologies for CSO or SSO, as well. The disinfection technologies should be of pilot-scale size, within the approximate capacity range of 50 to 200 gpm, and be either installed or planned to be installed within the next six months at an existing wastewater treatment plant (WWTP) that treats combined or sanitary sewage during wet weather events. The demonstration/evaluation effort should include a UV- generated chlorine dioxide unit and two or more units of different disinfection technologies of interest such as UV light irradiation and high-voltage electron beam irradiation. The units should be connected or planned to be connected within the next six months to the influent and/or effluent of the WWTP primary clarification facility. The estimated duration of this effort is twenty four months from date of award. EPA intends to issue a request for a written quotation (RFQ). The RFQ-OH-97-00243 will be issued on or about July 21, 1997 with written quotations due on or about August 1, 1997. All responsible sources may submit a written quotation which will be considered by the Agency. Requests for the RFQ must be in writing. NO TELEPHONE REQUESTS WILL BE ACCEPTED. E-mail or faxed requests are acceptable. The fax number is (513) 366-2004. The mailing address is 26 W. Martin Luther King Drive, Cincinnati, OH 45240. (0184)
