Many problems with the floating bed?

Recently, our company’s floating-bed reactors (the anion and cation beds are floating-bed types, while the mixed-bed is a fixed-bed type) have been experiencing frequent problems. The specific issues are as follows: 1. Resin leakage; 2. Damage to the rubber lining inside the bed layer; 3. Damage to the resin trap at the outlet; 4. Severe corrosion of the filter caps inside the bed layer. I’d like to know what could cause so many problems to arise (The on-site conditions show that the pressure at the outlet of the centrifugal pump is generally around 5.5 kilograms. The general flow is as follows: the water exiting the centrifugal pump first passes through 12 sets of sand filters; the water coming out of these sand filters then goes into 12 sets of carbon filters. The water emerging from the carbon filters enters 5 sets of floating cation exchangers, and the water from those exchangers flows into an intermediate tank. From this tank, the water is pumped under pressure into 5 sets of floating anion exchangers, and the water from those exchangers goes into 5 sets of mixed-bed exchangers. For every 3 sets of sand filters and carbon filters, there is 1 set of cation exchangers, and for every set of cation, anion, and mixed-bed exchangers, there is 1 set corresponding to it.)
