Inquiry (采购产品): BIOFILTER ATMOSPHERIC I am currently working on a project the will use a 4" atmospheric vent pipe from a large underground storage tank. The storage tank will contain potable water. Our intent is to filter the air that the storage tank will breath. We need something that will not pass airbourne bacteria. The storage tank volume is 6000 gallons. The make-up rate will not exceed 10 gallons per minute. The draw-down rate could be as much as 200 gallons per minute under peak or stressful conditions. Please get back to us as soon as possible with any information you may have. **** Hidden Message ***** James Witherspoon 201 East Lafayette Street Norristown, PA 19401 USA Company: Duff Supply Co.
