The effect of macroporous resin adsorption rate is the most obvious.

The existing resin columns all use a single cylindrical pipe (volume 1 cubic meter) for the material to pass through. In order to prolong the flow time of the material in the resin column to ensure full contact between the material and the resin, the height-diameter ratio of the pipe is mostly set at 10-15, in order to achieve this height-diameter ratio, the length of the pipeline is longer (generally more than 5 meters), which in turn causes the overall volume to be larger, occupying more space, and the resin at the bottom is easily broken and lost under pressure. The sand board is easy to break, and at the same time, the fluid will form an irregular inertial flow channel due to the wall effect, resulting in the phenomenon of drift and turbulence, the adsorption rate fluctuates greatly, the exchange efficiency is low, and it also increases the difficulty of filling and replacing the resin. for further improvement.
