How long will Tripolymer Tank Media last when installed in an under ground oil storage tank?
A. Over the past 25 years many samples of Tripolymer Tank Media have been recovered and tested from under ground oil storage tanks, from under concrete floor slabs, from mine shafts and other subterranean applications. These samples showed minimal, and in most case no structural, bacterial or water degradation. The samples ranged from 8 to 26 years in age. Taking into consideration the volume of a 550-gallon oil storage tank and a lack of degradation of the samples tested, Tripolymer TM. Tank media should maintain its structural integrity for many hundreds of years into the future.
