Ion Exchange Column Design Calculations

Steps to design an ion exchange resin system accurate system design is critical to getting the most from a water treatment system.

Ion exchange column design calculations.

Since dozens of factors can impact the productivity of the system the cadix system design software program from dow offers precise design recommendations to optimize system performance. Only a few general recommendations to ensure that an ion exchange system is designed economically and to achieve good performance and a simple but detailed example. The calculations are made using theoretical equations. Basic column types are shown in another page.

A breakthrough curve shown in figure 13 6 has been obtained from an experimental laboratory column on the sodium cycle. The allowable effluent concentration ca is 5 co. As a consequence this calculator only gives you an indication about the different parameters that are necessary to design an ion exchange water treatment installation. The ammonium concentration of permeate is 0 14 mg l.

The calculator is based on the following process. Example 13 1 si ion exchange in waste treatment an industrial wastewater with 107 mg l of cu2 3 37 meq l is to be treated by an exchange column. Ion exchange column design assumptions. Ion exchange plant design some basic principles you will not find here a complete plant design manual.

Data concerning the. Each unit with a capacity of 120m3 hour average breakthrough capacity of 2 17 mg g 1606 mg l at 20 cm bed height is used for calculation for different bed heights.
