Water Research Laboratory has been commissioned to cater the requirements for undertaking major research activities of water and environmental stream. The facilities have been meticulously created to carry out studies related to the research projects. The major experimental set-ups developed for undertaking research include:

  • Particle image capturing and processing system (for floc characterization and find applications in coagulation and flocculation studies in water and wastewater treatment, estuarine sediment dynamics etc.)
  • Settling column facility (for estimation of settling velocity and find applications in sedimentation tank design of water and wastewater treatment, sediment settling in natural water bodies etc.)
  • Electrocoagulation reactor (for wastewater treatment applications)
  • Photocatalytic reactor (for wastewater treatment applications)
  • Annular flume (for simulating continuous flow studies as in natural environment)

The major research projects carried out utilizing the facilities of the laboratory include:

  • Studies on the seasonal variation of heavy metal distribution in a shallow estuary (2013-16)
  • Degradation of industrial wastewater using hybrid electrocoagulation-photocatalytic oxidation system (2017-20)
  • Studies on the dynamics of suspended sediments in a deep estuary on the south-west coast of India (2018-19)
  • Development of Trophic State Index for freshwater and brackish lake ecosystem of southern Kerala (2019-21)
  • Development of Water Quality Index for the assessment of trophic status of an estuarine system (2019-20)

Some of the outcomes of the research projects can be evidenced through publications in reputed journals and conferences. The research publications during the last 3 years include:
