Fluorides and fluorosilicates have been widely used in many industrial plants. Hence, there are many hazardous wastes which contain high fluoride. Fluoride gases were reacted with fiberglass at high temperature and the reaction studied as a function of percentage of moisture. Keeping the quench tower, in front of baghouse, in a good working condition can efficiently reduce the attack to the filter bags from the fluoride gases. Aptus, wholly owned by Rollins Environmental Services, currently operates several environmental service facilities in the US. One of six high-temperature incinerators in Rollins is located in Aragonite, UT, which burns hazardous and industrial wastes and features a state-of-the-art air pollution control system.
