<p>An electrostatic electrode (9) placed directly in a storage tank (6) of a water system. Hitherto, the electrode has been placed in a water jacket which is connected into the pipework. Improved consistency of de-scaling performance is thereby achieved, and the cost of installation is much reduced. Also disclosed is a construction of electrode that is well suited to mounting without the protection of an enclosing jacket or pipe, the construction being based on the use of a screwed rod (48) passing down the centre of the electrode, and insulated from the mounting means (40).</p> |
