What is the structure of Dowex 50X2 100 ion exchange resin?

How can we calculate total capacity of a resin?

We now have to multiply this by 7.48 gal/cu ft to equate the number to a cubic foot of resin: 2,923.98 x 7.48 = 21,871. So 1 meq/mL is equal to 21.87 Kgr/cu ft. A new resin with 2.0 meq/mL has a total capacity of 43.74 Kgr/cu ft.

What is exchange capacity of resin?

In general terms, the capacity of an ion exchange resin can be expressed as the quantity of ions that can be taken up by a specific volume of the resin. A measured quantity of caustic (NaOH) is then passed through the resin so as to totally exhaust the resin.

What is Dowex HCR-s/s CR?

Pressure Drop Data Typical properties and applications: DOWEX HCR-S/S cation exchange resin is a high capacity resin with excellent kinetics and good physical, chemical, and thermal stability. DOWEX HCR-S/S is used for domestic applications in the co-current mode of regeneration. For counter-current regeneration, DOWEX HCR-S/S CR is available.

Why choose Dowex ion exchange resins?

Food and Beverage: DOWEX Ion Exchange Resins help manage natural food and beverage variability to ensure a more dependable set of characteristics such as taste, color and texture. Industrial Water Treatment: Ion exchange (IX) was the first technology employed to fully demineralize water and we haven’t stopped there.

What is Dowex Marathon c(Na form) resin?

Buildings & Institutions: DOWEX MARATHON C (Na form) resin is perfect for institutional applications and features uniform beads that exhibit faster kinetics than conventionally sized resins and helps improve regeneration efficiency and higher operating capacity.

Which grade of Dowex resin is used for demineralization?

DOWEX HCR-S resin is used in softening as well as single or mixed bed demineralization. In addition to the standard grade, DOWEX HCR-S MB (H) and DOWEX HCR-S PS are specially graded resins for use in mixed bed and counter-current regeneration applications respectively.
