Environmental technology lab

NIVA has a strong research team that contributes knowledge to understand the problems, processes and solutions for managing drinking water, pool water, wastewater, stormwater and process water from various industrial processes. 

Examples of industrial processes include metallurgical industry, aquaculture and aquaponics, mines, laundries, and others.

Central to this research is that we can conduct experiments with different nature-based and technical purification solutions at different scales (lab, pilot and full-scale) for different types of water.

Our researchers study how we can purify the different types of water from particles, organic matter, nutrients, pollutants and pharmaceuticals, as well as inactivate or remove pathogens, antibiotic resistant microbes and genes.

We also study how we can harvest energy, nutrients and metals from the water, and how this is part of a more sustainable use and reuse of resources. This is thus a contribution to a future circular economy.

Different purification solutions we work with:

  • Heavy oxidation processes (AOP)
  • Light treatment with UV and blue light
  • Filter and membrane technology (micro-, ultra-, nano- and RO-)
  • Biological wastewater treatment processes (activated sludge, biofilm and gel embedding)
  • Use of microalgae for treatment
  • Microbial electrolytic cells (MEC)
  • Chemical precipitation and flocculation
  • Adsorption and resorption to different types of sorbents
  • Stripping/vapor stripping and condensation
  • Nature-based digestion and purification solutions such as treatment ponds and rain beds

We also work with different types of characterization:

  • Particle size distribution
  • Sedimentation rate of particles
  • Leaching potential from different types of materials to water
  • Degradation potential of different types of compounds (in collaboration with Ecotox...)
  • Easy determination of microorganisms
  • Potential for the formation of disinfection by-products
  • Viscosity
  • XAD fractionation of natural organic matter
