TER Quest

TER Quest

The TERquest product line comprises synergistic blends of effective components to prevent mineral scalings in waterbearing systems.


TERquest antiscalants are used in aqueous systems to suppress the formation of deposits (scaling) based on mineral salts such as carbonates and sulfates. A precipitation is prevented due to the excellent dispersing properties. TERquest antiscalants can be provided in potable water treatment quality upon request. Besides the treatment of waterbearing systems, they are also suited for the feed water conditioning of RO membrane filtration systems.
