Inquiry (采购产品): Sand and Media Filters I am a senior at the University of Portland, majoring in civil engineering and am currently working on a year long design project. The project is looking at expanding an existing aerated lagoon wasterwater treatment plant. I am interested in information regarding your sand and media filters for a plant that has a current flow of 0.046 MGD and is looking to expand. Thanks for your time. **** Hidden Message ***** Rachel Litton 5000 N Willamette Blvd H 210 F Portland, OR 97203 USA Company: University of Portland Title: student E-mail: rlitton@up.edu **** Hidden Message ***** rlitton@up.edu
