Chemical treatment for algae control in open water systems.

摘要

Algae growth in an open water system such as a water cooling tower is controlled by reducing the amount of light available for the algae to photosynthesize. The light available for photosynthesis is reduced by incorporating a dye into the water in the water cooling system. Thus the dye absorbs the light necessary for photosynthesis and in turn prevents algae growth. Preferably fluorescein at a concentration of 0.2 to 800 parts per million is incorporated into the water in the water cooling system. Other dyes can be selected depending on the particular algae.
