Abstract:
Nowadays major attention is paid to the development of comprehensive industrial wastewater treatment, that ensures sufficient purification for recycling the water supply and further utilization of the treatment-generated waste [1]. In this connection, we used the ferritization process for treatment of the rinsing water of electroplating lines [2].
In this work, the authors apply the ferritization process to also reduce initial concentrations of heavy metals in exhausted electroplating electrolytes from 100 g/l to 0.3 mg/l, in order to treat water to meet all requirements for its re-use. Effects of main technological parameters of such wastewater treatment were determined experimentally. The kinetics of heavy metals removal from aqueous solutions were studied. Economic feasibility of applications of the electromagnetic pulse method for solution activations in the range of generated frequencies up to 0.9 kHz is shown. Phase compositions of sediments from the wastewater treated were studied by X-ray diffraction and scanning electron microscopy. The sediments are predominantly characterized by crystalline structures, ferromagnetic properties, and chemical stability, supporting opportunities for environmentally sound utilization.
In contrast to traditional reagent-based wastewater treatment methods [3], we propose a comprehensive process for treating liquid industrial waste flows with the introduction of a recycling water supply, that would prevent environmental contamination by toxic effluents, and ensure the efficient use of water, raw materials, and energy inputs in industrial facilities.
