CSR Plus® LF is a more aggressive cleaner of scaled concrete or painted steel surfaces and is less corrosive than most acidic de-scalers. Cleaning air stripper media with CSR Plus® LF is an alternative to costly media replacement. This is a liquid descaling product for the removal of heavy calcium carbonate and other mineral deposits from filtration basins, troughs, clarifiers, and other accessible water treatment plant surfaces. CSR Plus® LF is also used to clean air stripper media or as an off-line pipeline treatment. CSR Plus® LF is not a potable water treatment additive and therefore cannot be injected directly into potable water.
