Abstract
A multiple tank filtration system can be backflushed to remove the material on the loaded adsorbent at a high rate of liquid flow through the use of a tank connecting distributor which has pervious projections extending therefrom into both the first and second tanks. The pervious projections extending into the first tank are less than those which extend into the second tank. This provides for a greater flow of liquid during backwash.
