Abstract
The proposed technology relates to a system (8) for preventing microbiological growth in a conduit conveying a liquid. The system (8) comprises a multi-layered pipe (10) constituting said conduit and having an inner layer (12) that covers the complete inside (16) of the pipe (10) and is formed of an electrically conductive polymer material. A liquid in the pipe (10) is in direct contact with the inner layer (12). The system further has a first electrical connector (18) and a second electrical connector (19) connecting to the inner layer (12) from outside the pipe (10), wherein the first electric connector (18) and the second electric connector (19) are spaced apart along the pipe (10). The system further has an electric power source (20) operationally connected to the first electrical connector (18) and the second electrical connector (19) and configured for supplying an electric current to the inner layer (12).
