Abstract
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.
Claims15
A continuous resin regeneration system for use in cleaning water from a contaminated water reservoir, comprising:
- a first filtration column defining a first interior area and having a first resin inlet operable for receiving a first resin into said first interior area at a first resin flow rate that is a predetermined resin flow rate, a first resin outlet operable for directing a first degenerated resin portion of said first resin out of said first interior area, a first water inlet operable for receiving a contaminated water stream into said first interior area at a water flow rate, and a first water outlet operable for directing said contaminated water stream out of said first interior area according to said first resin flow rate;
- a second filtration column defining a second interior area and having a second resin inlet operable for receiving a second resin into said second interior area at a second resin flow rate which is a predetermined resin flow rate, a second resin outlet operable for directing a second degenerated resin portion of said second resin out of said second interior area, a second water inlet in communication with said first water outlet operable for receiving said contaminated water stream into said second interior area at said water flow rate, and a second water outlet operable for directing said contaminated water stream out of said second interior area;
- an initial total dissolved solids (TDS) meter in communication with said first water inlet for determining an initial degree of contamination of said contaminated water stream prior to said water stream entering said first interior area;
- a first total dissolved solids (TDS) meter in communication with said first water outlet that is operable for determining a first degree of contamination of said contaminated water stream after said contaminated water stream has passed through said first interior area;
- a second total dissolved solids (TDS) meter in communication with said second water outlet that is operable for determining a second degree of contamination of said contaminated water stream after said contaminated water stream has passed through said second interior area;
- a first resin controller operable for determining a third resin flow rate by evaluating said initial degree of contamination relative to said first degree of contamination and said first resin flow rate, said third resin control rate increasing or decreasing said first resin flow rate according to said comparisons of said initial degree of contamination, said first degree of contamination, and said first resin flow rate, respectively;
- and
- a second resin controller operable for determining a fourth resin flow rate by evaluating said second degree of contamination relative to said first degree of contamination and to said second resin flow rate, said fourth resin control rate increasing or decreasing said second resin flow rate according to said comparisons of said second degree of contamination, said first degree of contamination, and said second resin flow rate, respectively.
