Hybrid Adsorptive and Oxidative Removal of Natural Organic Matter Using Iron Oxide-Coated Pumice Particles

Figure 2

NOM removals in MB water by the original or iron oxide-coated pumice particles (adsorption only), hydrogen peroxide alone, and the hybrid process (iron oxide-coated pumice and peroxide). UV reductions (a) and DOC removal (b). <63 µm Isp pumice, pumice dose: 3000 mg/L, reaction period: 24 h, and initial DOC: 4.1 mg/L. Error bars indicate the 95% confidence intervals.
