Purpose and goal
The SWIM project aims to develop an innovative solution for small-scale residential wastewater treatment based on novel recyclable filter materials. The SWIM solution is based on a series of filters that can remove 100% of the phosphorus, 50% of the nitrogen and 99.9% of the bacteria while enabling the recycling of nutrients, in particular phosphorus.
Expected results and effects
The project impact is twofold: 1. Reduced nutrient discharge to water sources, preventing the eutrophication process and therefore protecting aquatic life and water quality 2. Increased recycling of phosphorus that can reduce the use of commercial fertilizers, reducing the pressure on the limited supply of phosphorus, and providing cost-savings to the agricultural industry
Planned approach and implementation
A Swedish-Polish consortium has been established to tackle the problem of nutrient capture and recycling in small-scale decentralized wastewater treatment systems: four SMEs in Sweden and Poland (Ecofiltration Nordic AB (Bioptech AB), Bioptech Sp z o.o., Dot-Eko and POMInnO), and a leading-edge university (KTH - Royal Institute of Technology) focusing on environmental technologies.
