OT ?DL?@TT?IB*cBB Activates Silica with Chlorine Activated silica is a powerful coagulant aid and has been used
in water and waste treatment for many years. The coagulation and sedimentation of waters that are difficult to treat using the usual coagulation chemicals and methods are improved
when activated silica is employed as a coagulant aid.
The WT Silactor? (pronounced Sill-actor) prepares and applies chlorine activated silica on a continuous basis. Cumber
some, space-consuming batch tanks are eliminated by the easily
controlled, compact WT SilaGtor. Sodium silicate is pumped
directly from the shipping drum and is rapidly activated by metered chlorine within the unit. The storing and handling of
acids or uncommon treatment chemicals are eliminated.
For complete information about the WT Silactor?, ask your local Wallace & Tiernan representative for Catalog File
60.110, or write to the address below.
