Fluid treatment system
View Patent ↗A fluid treatment system comprising at least two cylindrical vessels, wherein each vessel contains at least one treatment medium selected from ion exchange resins, polymeric adsorbents, inorganic adsorbents and activated carbon; each vessel has at each end a flat head and a fractal liquid transfer manifold; and the system comprises at least one membrane degasifier unit.
1. A method for treating water comprising passing water at a flow rate of at least 30 m 3 /hour through a fluid treatment system comprising at least two cylindrical vessels containing ion exchange resin, wherein at least one vessel contains an anion ion exchange resin and at least one vessel contains a cation ion exchange resin; the anion and cation ion exchange resins are beads having a harmonic mean size from 400 microns to 700 microns, and having at least 95% of beads no more than 50 microns from the harmonic mean size; each vessel has at each end a flat head and a fractal liquid transfer manifold; an inside diameter of each vessel is from 0.75 m to 1.25 m; and the system comprises at least one membrane degasifier unit.
2. The method of claim 1 in which said at least one vessel containing an anion ion exchange resin and said at least one vessel containing a cation ion exchange resin are substantially equal in size.
3. The method of claim 2 in which the fluid treatment system has two vessels containing an anion ion exchange resin and two vessels containing a cation ion exchange resin.
4. The method of claim 3 in which the fluid treatment system is constructed in two parts, each on a support frame, each part having a width no more than 2.30 m, a height no more than 2.37 m, and a length no more than 6.08 m.
5. The method of claim 4 in which a height of each vessel is from 1.2 m to 1.3 m and an inside diameter of each vessel is from 1.1 m to 1.25 m.
6. The method of claim 5 in which the flow rate is at least 50 m 3 /hour.
