MuFil (Mussel Filtration)

Innovative biological water filtration and water quality indicator concept, founded on mussels' water filtration capability for drinking water, domestic water, stormwater, leachate, and nutrient-rich wastewater filtration.

Mussels are essentially living water filters, making biological filtration an effective chemical-free option with wide use cases. The mussels are not in danger nor disturbed in their task: it's a win-win for everyone.

MuFil innovation concept was developed by Matti Mako.

Mussels for water filtration

Mussel filtration significantly reduces pathogens and parasites, and removes humus, clay, and microplastics. Of special interest is the efficacy of also removing bacteria such as coliforms, E.coli, and enterococci.

Despite harming the quality of water, these problems are perfectly suited for mussels as nutrients, which is an essential part of mussel filtration. Water quality is measurably improved.

Use as water quality indicator

Several anomalies in drinking water can be identified very quickly with the water quality indicator, which is field-ready and easy to transport between different water systems and sites.

Finnish work in a clean Finland

The concept paves way for a strong foundation of Finnish work in a new field, starting from production to responding to previously difficult and expensive water filtration and quality monitoring problems.

Fully scalable from local operators and consumer needs to the industrial segment.

MuFil research group develops the concept at an academic level, providing essential research especially on drinking water quality monitoring and water safety.

Water quality indicator testing has started in 2025.
