Traditional and polymeric quat-based algaecides are known to be incompatible with anionic scale and corrosion inhibitors. However, Bardac® LF 18-50 WT can be applied with confidence to water systems that use these compounds. Because of its unique chemical structure, Bardac® LF 18-50 WT demonstrates minimal interaction with anionic treatment chemicals while retaining the outstanding algaecidal performance of traditional ADBAC quats. In addition, compared to ADBAC quats, Bardac® LF 18-50 WT is low foaming. The use of ADBAC algaecides is often limited because of the prob-lems associated with the high foam levels that they can create. Bardac® LF 18-50 WT exhibits low levels of fast breaking foam, which allows for application in dynamic systems with high recirculation rates.
