Red water is generated in the process of 2,4,6-trinitrotoluene (TNT) production. These waste effluents have high loads of non-degradable organics which are difficult to treat. Previous Conventional technologies applied to treat this are associated with higher energy expenditure and secondary pollution. However the cooling crystallization has the lower energy expenditure and no secondary pollution and no require addition of chemicals. In the study, 100-fold diluted TNT red water is cooling crystalized using continuous drum crystallizer. after then it is compressed up 50% at the column that connected temperature controller while melting by 5, 10, 15, 20, 25℃. Concentration of 100-fold diluted TNT red water is 150ppm. When red water treatment as compression ratio 50% and melting temperature 5℃, concentration of product is 2.4ppm. |
