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

摘要

A method of dissolving and/or inhibiting the deposition of scale on a surfaceof a system comprises the step of bringingthe surface of the system into contact with a composition. The composition cancomprise from about 3 to about 15 parts byweight of a chelating component. The chelating component is selected from thegroup of MGDA, NTA, HEDTA, GLDA, EDTA,DTPA, and mixtures thereof. The composition can further comprise from about 3to about 15 parts by weight of an acidic component,which is different than the chelating component. The composition can furthercomprise at least about 60 parts by weight of water.Each of the parts by weight ranges above are based on 100 parts by weight ofthe composition. The composition may furthercomprise a surfactant component and/or a corrosion inhibitor.
