Abstract
The deleterious effects of metal ions in water, for example water hardness and formation of deposits, may be combated by application of an algin, for example alginic acid or a salt of alginic acid, such as sodium alginate or potassium alginate. Such a compound may bring about water purification and/or softening and prevent formation of deposits. Furthermore, such a compound may promote the removal of existing deposits, for example scale.
Claims14
A method for removing metal salt deposits from a surface, comprising delivering an aqueous composition comprising an algin and an organic acid to an aqueous environment in which the metal salt deposits are present on the surface, wherein the composition has a pH less than about 7.
