Pictured: Calcite Acid Neutralizer After Installation. Yesterday we talked a little bit about neutralizing water without a calcite neutralizer. However, for best results, we recommend using a standalone calcite neutralizer tank. Today one customer wrote to us to ask about the potential drawbacks of using a calcite neutralizer, and we wanted to ...
>Autocatalytic degradation of Cu-EDTA in the Calcite/PMS …
As shown in Fig. 1 a and b, the combination of calcite with PMS resulted in the simultaneous decomplexation of 99.5 % Cu-EDTA and the removal of 61.9 % Cu ions within 60 min. In contrast, the separate application of PMS and calcite did not effectively decomplex Cu-EDTA and remove Cu ions. These results suggest that the interaction …
