Lime softening clarifier

NettetIt is used principally for clarification, lime softening, silica reduction, or organics reduction of water and wastewater containing suspended solids, color and organic impurities. As such, the Reactivator provides a means for chemical addition and mixing, flocculation, and upflow clarification in a single unit. Nettetclarifier units have their origins in the 1940s and 1950s. The two most common applications for the solids CONTACT CLARIFIER are cold lime softening, where the unit is used to maximize the rate of chemical precipitation, and surface water clarification, where the unit is used as an enhanced flocculation device.
