In a Packed Bed DI System, feed water enters the packed bed upward in the service cycle and downwards in the regeneration cycles. In the upward service cycle, the resin bed is lifted up in a compacted state, which minimizes the need for regular backwashing. As the water progressively comes into contact with the more regenerated resin, which is the resin in the upper portion of the bed since the regeneration is downward, high quality water production is ensured with lower ionic leakage.
Effluent from the regeneration of Packed Bed DI System is generally neutral due to the equivalence of cations to anions, also, acid and caustic are both introduced into the packed bed at the same time during regeneration.
Fully packed resin tanks give higher throughput compared to conventional systems. Counter current regeneration provides better water quality compared to co-current design. It also facilitates efficient and shorter regeneration time.
Excellent Information,it was helpful to me. Do you know where I can find more information about ion exchange resins? That is due to I am doing experimental research about water treatment with the purpose of getting my bachelors degree and I need good information. My e-mail is cruzjil@gmail.com and I am from Mexico, thank you.
