Solving eutrophication with sustainable, scalable technologies

We are researching how modified local soil can remove algae and improve water quality. Our approach cure polluted sediment and turns excess nutrients into resources for ecological restoration and biodiversity conservation.

Water quality affects everything from public health to local industry. It is vital we develop cost-effective and environmentally friendly ways to control harmful algal blooms and restore polluted water.

Addressing the Challenge

Field-tested, proven impact

Led by Professor Gang Pan, the team at NTU has developed a methodology that uses modified local soil (MLS technology) to:

  • remove algae
  • improve water quality
  • remediate polluted sediment
  • reduce internal loads
  • restore eutrophic water for biodiversity conservation

We have already used the technique commercially in China. A number of engineering projects have seen immediate and sustainable effects.

Making a Difference

Conceived in Nottingham, applied worldwide

Our developments could have a big impact so we are collaborating with organisations across the world to maximise the opportunities:

  • Research Centre for Eco-environmental Sciences, CAS (China)
  • Beijing Advanced Science and Innovation Centre, CAS (China)
  • Waikato University (New Zealand)
  • Rotorua District Council, New Zealand
  • Roto-Ora Ltd, New Zealand

The outcomes of this study will provide a cost-effective and sustainable technology to solve the worldwide problem of eutrophIcation - Professor Gang Pan
