Perchlorate Treatment Technologies: Perchlorate Concentration Ranges TreatedThe chart below illustrates the perchlorate concentration ranges treated or addressed in each of the case studies included in this report. Perchlorate concentrations were not specified in the majority of case studies reviewed; however, when provided, perchlorate concentrations ranged from <1,000 parts per billion (ppb) to >1,000,000 ppb. Research and treatment applications for drinking water sources accounted for the majority of the 15 low perchlorate concentration (<1,000 ppb) treatment projects. Projects with soil or groundwater contamination, or wastewater stream treatments (such as booster motor washout), accounted for those studies generally having higher concentrations of perchlorate. |
