The influence of water filtration rate on the efficiency of its oxidization on iron-containing redoxite

Experimet to determine the effectiveness of iron-containing redoxites on efficiency water deoxidation. In course study, dependence deoxidation filtration rate was determined. 
 The varied in range from 5 25 mph. residual oxygen content and dissolved iron were It shown that with increasing within these limits, concentration increases 0.1-0.2 mg/dm3 0.9-1.0 mg/dm3. depends not only but also reaction medium. An increase pH medium 6.7 10.0.
 Residual little both all cases did exceed 0.2 mg / dm3. this work, dissolution general determined by preliminary preparation for work redoxite.
 When used installation scheme, addition column redoxite, columns cation exchange resin KU-2-8 Na-form, almost complete removal ions natriation softening tap noted. case sodium-cationized water, extraction will be observed a long time, given low high capacity ions. addition, sorbed (II) are oxidized residues (III). latter, at elevated pH, hydrolyzed, which is reason restoration divalent cations.
 when after redoxite anion AB-17-8 sulfite form, achieved.
 Given use composite decreased 10-40 times, load redox decrease proportionally, means duration filter cycle same proportion.
 second stage SO32- form remained unchanged, achieved. option quite promising implementation.
