Roughening treatment
Thread Content
Water treatment structure No. 1 in the water plant – V-type filter. The construction specifications state that the filter tank walls should be textured; what does this mean? How is it done?
I saw on NetEase that someone said it is to prevent water entering the filter tank without passing through the sand filter, thereby avoiding short-circuiting flow.
I know the reason for this, but I don’t know what to do about it
Those who have done it before, please step forward and explain it to us! Let’s learn about it. First of all, thank you
