NA-05 - Cleaning: Cleaning Nozzles

Practical recommendations

Quality control

A form of quality control carried out during the cleaning operation involves assessing the noise created by the deposits during suction and visually inspecting the flushing water.

Acoustic assessment: mud, rocks or solidified deposits cause noise as they are vacuumed up and hit the suction tube. This provides insights into the degree of contamination and the progress of the cleaning.
