Alum jar tests were performed on raw portable waters of varying TOC. Parameters monitored include alum dose, pH and mixing conditions. Finished waters were analyzed for residual aluminum, residual TOC and hardness in order to investigate the effects of TOC on aluminum residual as would be encountered by alum coagulation and lime softening process in practice.
Three-dimensional graphs of residual aluminum, residual TOC and pH were constructed to illustrate the relationship among these measured parameters for the different sources. Statistical analyses were conducted to verify aluminum-organic complexation at reduced alum dosages for varying TOCs; initial TOC, reaction pH and dose were investigated for variability of TOC and aluminum data sets. Actual pC versus pH diagrams were also developed for all source waters for comparison with theoretical aluminum equilibrium profiles.
