Small-scale Wastewater treatment system based on Innovative filter Materials (SWIM)

Reference number
Coordinator BIOPTECH AB (PUBL)
Funding from Vinnova SEK 2 354 297
Project duration November 2015 - June 2018
Status Completed
Venture EUREKA cluster co-funding 

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.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
