The processes of determining the efficiency of Dawex Marathon WBA anionites in removing phosphates from water and creating waste-free processes for their regeneration were studied. In the course of an experimental study of sorption, model solutions of polluted water containing phosphates in a concentration of 40-100 mg dm-3 were passed through the low-based Dawex Marathon WBA anionite in chloride form. The dependence of TDEC on pH and temperature was established when filtering through low-base anionite DOWEX MARATHON WBA in chloride form. An important aspect of the research was the determination of the principles of extracting phosphates in the form of mineral fertilizer during repeated use of regeneration solutions. The processes of anionite regeneration have been studied. Regeneration of anionite was carried out with two solutions, in parallel, namely - 10 % solutions of sodium chloride, 10 % solution of ammonium chloride. It should be noted that the degree of regeneration is 97 - 98 %. [ABSTRACT FROM AUTHOR] |
