Experiments were carried out to study the influence of the conditions of TNRS synthesis on the formation of the crystal. The possibility of wastewater treatment of TNRS production using aqueous solutions of coagulants was studied. It was found that with increasing dosages of reagents, the volume of sediment increases, and the COD values of filtrates decrease. It was found that the highest degree of purification was achieved using iron (II) sulfate at a dosage of 10 g/dm 3 and was not less than 87.
