The problem may lie with the resin trap, as the resin column needs to discharge liquid through this trap during both forward and reverse washing processes. If the filter screen of the resin trap gets clogged by small resin particles, it will result in excessive resistance, which is manifested as high inlet pressure in the resin column during both forward and reverse washing. The resin catcher can be inspected; if necessary, a pressure gauge can be simply installed at the inlet of the resin catcher. This post was last edited by alaslxf on 2008-1-26 11:03.]
No, both import and export operations are normal, and the instruments are also working fine. Could there be any other reasons?
