What if we could reduce biofouling and clean less with fewer chemicals? 

We believe that biologicals and proper pump settings can offer new cost-effective and environmentally friendly ways to remove the biofilm that is formed by microorganisms. 


Specifically, we are looking for solutions to reduce cleaning frequency, decrease chemical cleaning harshness and elongate membrane life. 

This will not only benefit the environment and thousands of water purification plants. It will also help us purify more water, which is an absolute necessity for millions of people across the world.

This is the challenge for you if…

  • You want to reduce the environmental impact from harmful chemicals 
  • You want to reduce waste
  • You want to make water purification more affordable in a growing world

Submit your solutions and collaborate with startups, citizen science and NGO’s on HelloScience Collaboration space and get the ball rolling. 

More about the challenge

Biofouling occurs when microorganisms, algae, plants and other living creatures accumulate on wet surfaces. It’s no surprise that biofouling is a real problem at water purification plants where mechanical equipment and membrane filtration systems are drenched in dirty water year-around. 

The big issue with biofouling is that membrane cleaning requires harsh chemicals, which are not only harmful for the environment – it also increases the operational cost and shortens the membrane life. 

In a rapidly growing world where people are already running out of clean water, we simply need to find a more sustainable solution. 

Accelerate your project with a SciCube

Each month, we offer three unique SciCubes to the HelloScience community. To begin with, the winners of the SciCubes are selected by Novozymes. However, when we reach 100 collaborators, the power of choosing the winners will move to the community. 

Each SciCube* contains: 

  • A selection of enzyme and microbe samples from Novozymes. You can choose up to three samples in total. 
  • Cloud-enabled monitoring solution for one system including 1 year data subscription from Grundfos.
  • Skype meetings with experts from Novozymes and Grundfos matching your specific business/technical needs. 
  • A one-hour Skype meeting with Novozymes’ waste water team and investments team and/or Grundfos business development team tailored to the needs of your business or solution. 

*All SciCube® winners have the right to file patents within the water challenge theme, and there is no obligation to develop or commercialise any project with a specific partner. Samples are only to be used within the challenge theme and a simple SciCube agreement must be signed to receive the SciCube

Win a co-development opportunity with Novozymes and/or Grundfos

The best idea across all five water challenges will get a co-development agreement with Novozymes and Grundfos.  

The winner will get expert resources valued up to US$100,000 as well as lab access for trials or prototyping and specialist expertise within R&D, commercial and IP. All tailored to the needs of the winner and all to help the winning solution to a better product and a faster route to market.
