Abstract
The use of sodium chlorite for drinking water treatment has been increasing in the last several years. The performance of a variety of elastomers, FRP composites and other plastics during several months exposure to a 37% solution of sodium chlorite at 50 and 70°C is described. Materials were tested using ASTM C868-77 Glass Cell Test, creating immersion, vapour and cold wall effects. Issues of the permeation and thermal loading between the liner and steel surface were addressed. Laboratory studies resulted in the development of an experimental railcar tanker with an internal FRP composite liner suitable for high purity service.
