| abstract |
A method for dissolving and / or inhibiting the deposition of scale on a surface of a system is described, which consists in the step of bringing the surface of the system into contact with a composition. The composition may contain from about 3 to about 15 parts by weight of a chelating component. The chelating component is selected from the group of MGDA, NTA, HEDTA, GLDA, EDTA, DTPA and mixtures thereof. The composition may also contain from about up to about 15 parts by weight of an acid component, which is different from the chelating component. The composition may also contain at least about 60 parts by weight of water. Each of the ranges of the aforementioned parts by weight is based on 100 parts by weight of the composition. The composition may also contain a surfactant component and / or a corrosion inhibitor. |
