/ METHOD OF DISSOLVING AND/OR INHIBITING THE DEPOSITION OF SCALE ON A SURFACE OF A SYSTEM

摘要

A method of inhibiting and / or dissolving the deposition of scale on the surface of the system comprises contacting the surface of the system with the composition. The composition may comprise from about 3 to about 15 parts by weight of the chelating component. The chelating component is selected from the group consisting of MGDA, NTA, HEDTA, GLDA, EDTA, DTPA, and mixtures thereof. The composition may further comprise about 3 to about 15 parts by weight of an acidic component different from the chelating component. The composition may further comprise at least about 60 parts by weight of water. Each of the parts by weight is based on 100 parts by weight of the composition. The composition may further comprise a surfactant component and / or a corrosion inhibitor.
