ABSTRACT:
The growth of algae, fungi and pathogenic organisms in commercial and recreational waters, such as cooling towers, swimming pools and spas, may be controlled by adding to the water a primary sanitizing agent, preferably poly(hexamethylene biguanide) ("PHMB"), and a potentiating adjuvant comprising a calcium ion-chelating agent, preferably ethylenediamine tetraacetic acid ("EDTA"), in amounts such that the adjuvant renders the composition algicidal and fungicidal in water. The water may be further treated with a peroxy salt as a backup agent, preferably sodium perborate, or the calcium ion-chelating agent and peroxy salt may be combined as a shock treatment to water being treated with the primary sanitizing agent.
