Water Treatment Process Adapted to Change

Environmental and societal conditions change all the time, creating impacts water service cannot avoid its consequences of. It is vital to understand and take necessary measures to mitigate those impacts. With the participation from 38 organizations including universities, water utilities and private companies, JWRC has started a new collaborative program called "A-Batons". A-Batons aims to help adapt water treatment systems to various changes, having two specific objectives. One is to clarify impacts of water sources quality degradation that is affecting treatment process in wide areas and to find mitigation measures. The other is to identify technical know-how and experiences to be shared and inherited more widely among water utility staff members and to propose a set of tools that can assist skills enhancement of younger personnel.
A-Batons is a three-year program that started in 2015.
  

Ultraviolet Disinfection for Various Water Sources

To prevent cryptosporidium, Japanese government requests that water treatment facilities keep turbidity levels less than 0.1 degrees at the end of filtration process, but this control has proved difficult especially for smaller water supplies.
JWRC is now conducting a feasibility study of applying UV disinfection to surface water sources, hoping it would allow for easier turbidity control, in turn reducing the risks of pathogenic microorganisms.
For this purpose, we are proposing specifications as well as operation and maintenance requirements of UV facilities for a variety of surface water qualities.
