CALCULATION IN WATER TREATMENT DEAIGN FOR JOINTLY USING STRONG AND WEAK ACIDIC CATION EXCHANGE RESIONS[J]. Thermal power generation, 2003, (3): 29-32. DOI: 10.19666/j.rlfd.2003.03.009.
The suitable conditions for jointly using strong and weak acidic cation exchange resins have been expounded. The principle and procedure of calculation in design are given. The calculation is on the basis of operating capacity curves and formulae of the used resins. According to the original conditions
such as designed output
circle time
the temperature and quality of inlet water etc.
trial calculation of several times is needed to select the reasonable equipment
and to calculate the diameter of equipment and the bed heights of strong and weak acidic resins.
