Dr Sohan Shrestha

January 11, 2021 /

Sohan has almost 2.5 years’ professional experiences working as a researcher in different environmental projects associated with private/governmental organisations.  He has over 6 years’ research and development experience (particularly university-based) pertaining to developing and demonstrating innovative technologies for water/wastewater/wastes treatment and management, resource recovery from wastewater/sludge treatment processes, bioenergy recovery, integrated urban water management, with proven ability to work in an outcome-oriented environment under minimal supervision/independently and lead a multidisciplinary team.  He has completed his PhD in environmental chemical engineering in 2020 from Advanced Water Management Centre (AWMC), School of Chemical Engineering, The University of Queensland (UQ).  His PhD research focuses on exploring the mechanistic understanding of integration of iron-based salts or iron-rich sludge for multiple benefits across the urban water system.

His key areas of research interest or expertise include the following sectors:

  • Sludge and biosolids management derived from water/wastewater treatment systems
  • Biological nutrient removal and recovery from wastewater
  • Resource (e.g. energy, phosphorus, bioplastics) recovery from wastewater treatment plant
  • Energy efficiency of wastewater treatment plant (i.e., achieving energy positive or energy neutrality in wastewater treatment plants)
  • Biofuel/biodiesel synthesis from waste cooking oils and non-edible oils (castor and Jatropha plant seeds) using renewable resource-based catalyst
  • Energy policy and energy economics
  • Water treatment and quality assessment
  • Greenhouse gas (GHGs) emission from wastewater systems
  • Corrosion and odour control and management in sewer systems
  • Membrane technology and plasma irradiation process application for organic and inorganic pollutants remediation from water/wastewater
  • Integrated urban water management; water reuse and recycling
  • Efficient reusing waterworks-derived chemical sludge and mine wastes/tailings (generated from mining industry); mine waste management; mine closure
  • Monitoring and assessment for environmental pollution
  • Bioremediation engineering of contaminated soil
  • Assessment and management of environmental and biodiversity issues
  • Environmental policy, planning and management with emphasis on nature conservation/protection
