FBC (Fluidized Bed Crystallization) Technology

Fluidized bed crystallization (FBC) technology is revolutionary technology compared to conventional precipitation/clarifier process on many inorganic chemical removal, including heavy metals, N/P, fluoride and water softening. It uses silica sand as carrier to recover metal salts or inorganic ions from wastewater in crystal forms. Properly controlled recycle flow provides mixing to maintain sand fluidization. Control of chemical reagent addition provides appropriate super- saturation for crystal formation. Crystals are discharged when the size is grown to 1 to 2 mm in diameter.
