Biochemica UK Ltd has successfully completed a full scale site trial of a new foam technology designed for cooling tower cleans. This novel approach does not require packing to be removed as per conventional cleans. Figure 1 below shows a schematic correlating to the areas shown after endoscope inspection in Figures 2 and 3. Figure 2 shows the endoscope results prior to cleaning and highlighted moderate scale and biofilm formation.
Scale deposits were also found to be concentrated towards the centre of the pack. Figure 3 illustrates the effect of cleaning after the foam application. It can be seen that a significant improvement in biofilm and scaling was achieved on all sections.
On the success of this trial further full scale site work has been commissioned and Biochemica hopes to offer this novel approach for cooling tower cleans in the very near future.
