摘要：The experiment was based on filtration of the highly aggressive water through the melaphyre bed.The quartz bed was non-reactive reference material.The aim of this work was to determine the ability of the melaphyre to remove aggressive CO2 during the chemical reaction.It was noted that a decrease of acidity of the filtrate in comparison to the feed and an increase of its alkalinity and pH.It was calculated that until the moment of exhaustion of the de-acidifying properties of the melaphyre, maximum amount of bound CO2 added to the water was 29.7 g CO2/L of the bed, and maximum amount of the aggressive CO2 removed from the water was 33.3 g CO2/L of the bed.Regarding very high content of the aggressive CO2 (116 mg/L average) in the feed only 28.76% of this component was subject to transformation into bound and affiliated CO2 in the filtrate.For the melaphyre bed the CO2 loss from the experiment system following from desorption was 7.80% of the total load of CO2 added with the feed.On the quartz bed the loss was slightly lower 4.56%.
