Scale control at high LSI and high pH without acid feed is difficult to achieve. The problem dramatically increases in cooling towers when PVC tower film fill is used. Compounds that are able to enhance the performance of typical scale inhibitors have been developed. When topped off with these enhancing compounds ,typical scale inhibitors are able to control calcium carbonate and silicate- related scale formation on metal heat exchanger and cooling water tower film till surfaces in cycled waters having high LSI ...
