Fluoride content and flow-rate of fertilizer plant wastewater from phosphoric acid and/or triple superphosphate (TSP) production lead to the discharge of several thousand tons of fluoride (F(-)) per year and even more for phosphate (PO4(3-)). Since sustainability is an important

Fluoride in drinking water may be present from natural sources or added as sodium fluoride (NaF), sodium silicofluoride (Na(2)SiF(6)) or fluorosilicic acid (H(2)SiF(6)). Results from an early study with rats suggested that, when ingested as Na(2)SiF(6), the absorption and excretion
