Wastewater treatment

Project: Integrated approach for industrial wastewater and stormwater management in wood-industry sector

This project mainly financed by KK-stiftelsen (Knowledge Foundation) was the platform for the Triple Helix collaboration on industrial water handling in Småland and the islands.

More about the project

The problem and goals

Both highly contaminated wastewater streams generated indoor by the wood floor industry after cleaning and washing machinery and surfaces as well as large volumes of runoff from logs storage areas after irrigation of logs required proper characterization and the development of cost-effective, easy to handle one-site treatment options. The relevance was mostly to protect the wastewater treatment plants and biological processes, as well as the receiving water bodies in the area and at the same time to meet increasing demands from the environmental authorities.

Project activities

The project has focused basically on: (i) physical chemical and ecotoxicological characterization of five different wastewater streams and stormwater runoff generated after precipitation and irrigation of logs; (ii) treatability studies using a wide range of techniques and strategies including separate and combined (coupled treatment) physical, chemical and biological processes, focusing on the development cost-effective and easy to operate on-site treatment options to meet increasing environmental regulatory demands; (iii) training MSc students to work in the environmental engineering market; (iv) produce scientific publications to disseminate innovative approaches and contribute to the scientific knowledge within the field; (v) producing PhD theses and doctors to work in research and education, as well as in the wastewater treatment field; (vi) disseminating societal awareness about the relevance of on-site treatment of pollution to protect the water cycle and the water resources.
