PURIFICATION OF DRINKING WATER FROM NATURAL RADIONUCLIDES AND MANAGEMENT OPTIONS FOR NORM
3-4 March 2020. Viimsi (Estonia)
The consumption of drinking water can be a source of additional radiation dose for humans, thus it is important to monitor and guarantee the compliance with the water radiological parameters. How to achieve that? Who is responsibility is it?
The LIFE ALCHEMIA European project, co-financed by the LIFE Programme of the European Union, aims to demonstrate the feasibility of environmentally sustainable systems based on bed filters to removal/reduce the natural radioactivity in water, and minimize the generation of Naturally Occurring Radioactive Materials (NORM) in the purification stages.
The organized seminar will focus on addressing the following topics:
- Naturally occurring radionuclides in drinking water – problem for the consumer or provider?
- Creation of Naturally Occurring Radioactive Material (NORM) in drinking water treatment plants – possible to avoid it?
- The potential of a new hydrous manganese oxide (HMO) technology to remove radiological and inorganic constituents (e.g. Fe and Mn) from drinking water.
- How to make and economic decision on the selection of water purification technology.
- Technical visit to the Viimsi DWTP where the project pilot plant is installed.
This seminar is aimed at DWTP operators, water suppliers/managers, Public Administrations, policy makers in the area of environment and water policies, mainly.
The participation in the seminar is FREE OF CHARGE.
The seminar will be in English.
