The biofilter is a water cleansing solution for large ponds and it is developed together with our partner Arcadis. The cascading fountain increases the oxygen levels in the water, whilst the plants remove excess nutrients. The removal of nutrients lowers the number of algea in the water, enhancing water quality and keeps the fish alive even during warm summer periods.

The recovered nutrients are harvested and reclaimed as technical materials. The plant fibers are used to create furniture.

A prototype is currently in use in Zwolle and in Wijchen.
