  1. TREATMENT OF WASTEWATER USING PHOTOCATALYSIS Sikder M Selimuzzaman

  2. Outline • Introduction • Methodology • Discussion • Conclusion

  3. Introduction • Effuent of industry is a mixture suspended, dissolved organic and inorganic pollutants • The level of treatment Preleminery Treatment (rags, sticks etc.) Primary Treatment (ss,om, etc.) Secondary Treatment (bio-organic Matter, ss) Tertiary Treatment (rss, Nut rient, etc) Advance Treatment (DM, SS)

  4. Effuent of industry

  5. Some AOPs

  6. How OHo mineralize the pollutant ?

  7. How photocatalytic degradation (PCD) occur?

  8. Photocatalytic degradation (PCD)

  9. Lay out of the photoreactor

  10. Photoreactor during the experimental run

  11. Results and discussion(Photocatalytic degradation of S2O3: Effect of UV light and TiO2)

  12. Figure: Photocatalytic degradation of S2O3 and corresponding formation of SO4

  13. Conclusions and recomendations • No S2O3 can be removed either UV or TiO2 or both. • Solar light in place of UV light lamp can be used to reduce the pollutant

  14. Thank you
