Nursecoast II - study visit to the Bure Misie settlement - day1

Today, together with the Nursecoast II project partners, we are working in the Koscierzyna municipality, where a study visit is currently taking place. The first item on the agenda of the event was to reach the pilot site - that is, the settlement of Bure Misie where work on an ecological wastewater treatment plant is well advanced. During the tour of the settlement we learned about the history of its establishment and today's mission. According to the rest of the agenda, we listened to presentations on the investment in the Bure Misie, the innovative nanobubbles technology and constructed wetlands (i.e. artificial wetlands designed to treat wastewater, rainwater or surface water in a way that resembles natural wetlands). Information was presented on other pilots being carried out under the project, as well as presentations by associated partners.

Zooming in on the project objectives, the activities are related to the optimization of wastewater treatment systems. The project focuses on research into the use of nano-bubbles in water treatment processes. The main idea is to improve the transfer of oxygen to water by using smaller and smaller bubbles to increase the efficiency of oxygenation. Nano-bubbles can be an effective tool, especially in systems where an increase in purification capacity is required without the need for plant reconstruction. Pilots are being conducted in various locations to adapt the technologies to specific conditions in different regions. Experiments focus on intensifying biological processes in treatment plants and testing various parameters related to aeration and water recirculation. One of the challenges of the project is the variability of hydraulic loading at different times of the year, especially during tourist seasons, where the number of visitors increases significantly. The project aims to provide technological support to local governments and engineers responsible for designing new wastewater treatment plants. Test results collected from different locations are to be used to create a toolkit to support decision-making, both at the technical and policy levels. The possibility of reusing waste water for irrigation was also analyzed, requiring additional research on water quality after treatment processes.
