Influence of Heating Rate and Burning Temperature on the Thermal Decomposition of Textile Sludge

Abstract

The generation of waste is a consequence of human action as a result of user and processor of raw materials. In effluents textiles sewage treatment, waste generation, especially the sludge, is a constant making it necessary to use alternatives for its management. This work aims to study the influence of the burning temperature on the thermal decomposition of textile sludge by Thermogravimetry and Differential Thermal Analysis in order to use it as an additive in concrete and / or pre-molded. The TG curves of textile sludge burned at temperatures of 110°C, 400°C, 450°C, 500°C, 550°C and 600°C showed at two to three steps of thermal decomposition. The infrared spectrum showed characteristic bands of SiO2, OH and CH and the spectrum of the sinterized sludge showed the elimination of OH and CH bands.
