Having come across biofilms where the water was treated with chlorine dioxide, the statement that ClO2 breaks down biofilm is not always true. The problem with ClO2 is that it is volatile and is lost due to pressure changes, turbulence and pressure changes and it is more hazardous to produce than hypochlorite. Chlorine dioxide residuals can rapidly disappear and there are organisms, which can develop in levels 0.1-0.2 ppm frequently found in waters.
