My major research focus has been on developing and investigating innovative treatment methods for water, wastewater and hazardous wastes. These include chemical, physical and biological treatment methods for both organic and inorganic contaminants. Among the novel treatment processes we have developed are autotrophic denitrification with sulfur electron donors, inorganic oxide adsorbents for wastewater reuse, ultra-high lime and ultra-high lime with aluminum process for scalant removal in recycled water and zero-discharge desalination, the biostrip process for biological and physical treatment, degradative solidification/stabilization, chromium stabilization in the vadose zone, sulfur and iron-based reactive adsorbents, and advanced reduction processes. This research incorporates both experimental and modeling activities and is integrated with graduate and undergraduate education.
