77-19: The Reduction of Chromate by Amine Phosphonates at a Low pH Tower Testing Controlling biofilm with traditional biocides

Controlling biofilm with traditional biocides typically require higher concentrations

and wet and dry cooling towers

and the buckling and joint strength of pultruded tubes were evaluated

and it will give a procedure to be used to compare the relative performance of the fills

77-19: The Reduction of Chromate by Amine Phosphonates at a Low pH Tower Testing Controlling biofilm with traditional biocidesDuring the last ten to fifteen years, major advances have ocurred in the technology of cooling water scale and corrosion inhibitors. One of the most significant advances started during the middle 1960's when the organophosphates were introduced commercially. These materials won rapid acceptance in industry because of their strong threshold effect and their high level of hydrolytic stability.
