摘要： A continuous resin regeneration system includes a process by which resin in need of being recharged is continuously cycled out of a filtration “column” as new resin is flowed in. Downstream filtration columns also undergo this cycling but at slower and related rates as the first column with the dirtiest water will naturally degrade resin faster than the downstream columns. Contaminated water is cleaned by the continuously cycled resin in multiple columns. The degree of cleaning of earlier filtration columns affects the resin flow rate of later filtration columns.
