Abstract:
1. A method for monitoring fouling in a fill portion of a cooling tower, the method comprising: (i) measuring a first density value of a fill portion of a cooling tower by transmitting radiation through at least one part of the cooling tower and detecting radiation that has penetrated through the at least one part of the cooling tower; (ii) adding a quantity of an anti-fouling agent to a water supply contacting the fill portion; (iii) measuring a second density value for the fill portion by transmitting radiation through the at least one part of the cooling tower and detecting radiation that has penetrated through the at least one part of the cooling tower after said anti-fouling agent has been added; and (iv) comparing the second density value to the first density value in order to determine the effectiveness of the anti-fouling agent.
