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.
