    摘要: The invention relates to a method of controlling silica scale in an aqueous system, including adding an effective amount of mixture of a first polymer and a second polymer into the aqueous system, wherein the first polymer and the second polymer each has at least one of a first structural unit derived from any of quaternary ammonium monomer, quaternary phosphonium monomer, and quaternary sulfonium monomer and a second structural unit derived from any of sulfonic acid, sulfuric acid, phosphoric acid, carboxylic acid and any salt thereof, the first polymer bears a first net charge or being neutral, the second polymer bears a second net charge opposite the first net charge or bearing positive net charge when the first polymer is neutral, the first structural unit is from about 1 mol % to about 99 mol % of the mixture.

    摘要: A method has been found for the removal of microbial biofilm on surfaces in contact with systems, including but not limited to aqueous systems, which comprises adding to the aqueous system an effective amount of a carbosilane-based surfactant to substantially remove microbial biofilm, from surfaces in aquatic systems, while presenting minimal danger to non-target aquatic organisms at discharge due to their very low discharge concentrations.
