| Good news for de-scaling of heating or irrigation pipes | |
| Clearwater Enviro Technologies, in Florida, USA, have developed a simple to use de-scaler called ‘Scaleblaster™’ in 3 versions depending on the diameter of the pipes (Model SB-200 for pipes up to 5cm in diameter; SB-400 for pipes up to 10cm and SB-600 for pipes up to 20cm). All models are designed for indoor/outdoor use. Scale is a coating or precipitate deposited on surfaces that are in contact with hard water. The most common form of scale is calcium carbonate. In horticulture scale is evident as hard white deposits which build up in the pipes and which can compromise irrigation or even cause equipment failure. The ScaleBlaster™ unit is composed of a signal cable that is wrapped several times around the pipe and an electronic unit that sends out a complex, dynamic current to produce extremely small, time-varying oscillating fields inside the pipe. When the strength of the oscillating field is varied with time and changes direction, an induced current is produced inside the pipe. As the induced electric field oscillates, all particles which have an electrical charge are affected by the induced field. This causes the unstable mineral ions to precipitate or collide with each other to the point where the calcium carbonate crystals grow until they become so large that there are no more surface charges left to stick to the pipe walls. These calcium molecules precipitate into an aragonite form and flow through the system. As a byproduct of this "snowball" effect, freed water molecules become available to remove existing scale, molecule by molecule. Aragonite is a form of calcite that stays in solution and does not adhere to surfaces. This action stops any further build-up of scale and because the solubility of the water is increased, existing scale is taken back into the water and gradually removed.
