Specifications include, but are not limited to: City Utilities is seeking proposals for the transportation and disposal of an estimated 200,000 gallons of non-hazardous waste waters generated from the chemical cleaning of John Twitty Energy Center's (JTEC) Unit 1 coal fired energy generation unit boiler. The chemical cleaning is scheduled for the week of May 11, 2020. The chemical cleaning process will be using diammonium EDTA. The estimated usage of EDTA used in the chemical cleaning process is 55,200 pounds. An estimated concentration of copper and zinc are 225 ppm and 50-100 ppm respectively. An estimated 300 pounds of iron are expected to be removed from the boiler tubes during the chemical cleaning process. Average pH of wastewater is 9 due to the presence of ammonia. Safety Data Sheets for additional chemicals used in the chemical cleaning process are included in Appendix A of the RFP documents. The boiler chemical cleaning process will consist of a series of filling and flushing of the boiler with chemicals until on-site chemist determine optimal copper and iron deposits have been removed. Frac tanks will be filled evenly during the flushing process to ensure all tanks have similar contaminate profiles.
