How long does the effect last? Compared with other devices, Scale-buster® has been developed with the size of precipitated particles being a prime consideration. Large particles have a much smaller surface area than their equivalent mass made up of relatively smaller particles. For this reason, they are much slower to re-dissolve in the water and subsequently the treated water has long-lasting effects. Water treated using Scale-buster® is likely to continue to do its job of removing old scale deposits from pipe-work for much longer than competitive products, which produce much smaller particles. The manufacturers were the first to use laser particle analysis to determine precisely what physical effects their product generated.
