Removal Of Target Ppcps From Secondary Effluent Using Aops And Novel Adsorbents, Venkateswara Reddy Kandlakuti
Removal Of Target Ppcps From Secondary Effluent Using Aops And Novel Adsorbents, Venkateswara Reddy Kandlakuti
Electronic Thesis and Dissertation Repository
Atenolol (β-blocker), Clofibric Acid (Lipid regulators) and Diclofenac (Anti-inflammatory) are the drugs widely used and reported to have adverse effects on fish and other organisms. These drugs are found at trace levels in lakes, rivers and sewage treatment plants and conventional treatment plants are ineffective to eliminate these at those levels. A high resolution LC-MS/MS was used to quantify these drugs at low levels. Various advanced oxidation methods were used for the present research to eliminate these drugs from secondary effluent. Complete removal of PPCPs was achieved by synthesizing immobilized TiO2 on a stainless steel mesh and using a combination …

This work presented a Spatially-Explicit-High-Resolution Life Cycle Assessment (SEHR-LCA) model for wastewater-based algal biofuel production, by integrating life cycle assessment, GIS analysis, and site-specific Wastewater Treatment Plants (WWTPs) data analysis. Wastewater resources, land availability, and meteorological variation were analyzed for algae cultivation. Three pathways, Microwave Pyrolysis, hydrothermal liquefaction, and lipid extraction were modeled for bio-oil conversion. This model enables the assessment of seasonal and site-specific variations in productivity and environmental impacts of wastewater-based algal bio-oil across the whole U.S. Model results indicate that wastewater-based algal bio-oil can provide an opportunity to increase national biofuel output. The potential production of algal …
