A groundbreaking study published in ‘Heliyon’, which translates to ‘The Sun’, sheds light on an innovative approach to treating industrial wastewater, a pressing challenge for many sectors. Researchers led by Mahdiyeh Bakhtiyari-Ramezani from the Plasma Physics and Nuclear Fusion Research School at the Nuclear Science and Technology Research Institute in Tehran, Iran, have explored the synergistic effects of non-thermal plasma (NTP) technology combined with aeration and filtration methods. This research could significantly impact the water, sanitation, and drainage sectors by offering a more efficient and cost-effective solution for treating organic pollutants.
The study highlights the shortcomings of conventional wastewater treatment methods, which often struggle with high operational costs, inefficiencies, and the production of residual sludge. In contrast, NTP technology, known for generating reactive oxygen and nitrogen species (RONS), presents a promising alternative. “Our findings demonstrate that the integration of NTP with traditional methods can drastically enhance the degradation pathways of pollutants,” Bakhtiyari-Ramezani stated.
Using a dielectric barrier discharge (DBD) reactor, the research team treated wastewater samples from Kaveh Industrial City. The results were promising: a combination of aeration and 90 minutes of plasma treatment significantly reduced turbidity levels. Notably, a 30-minute NTP treatment paired with aeration and filtration showcased remarkable efficiency in removing total dissolved solids (TDS) and total suspended solids (TSS). This indicates that industries could see a reduction in wastewater treatment times and costs, ultimately leading to better compliance with environmental regulations.
The study also reported that optimal removal of chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) was achieved through a comprehensive treatment process involving 24 hours of aeration, adsorbent filtration, and a 30-minute NTP application. “The combination of these methods not only improves water quality but also contributes to environmental protection,” Bakhtiyari-Ramezani added, emphasizing the dual benefits of this approach.
As industries face increasing scrutiny over their environmental impact, the potential commercial implications of this research are substantial. The ability to treat wastewater more effectively could lead to lower operational costs, reduced environmental fines, and enhanced corporate sustainability profiles. The integration of NTP technology into existing wastewater treatment frameworks could pave the way for a new standard in the industry, making it a compelling area for future investment and development.
In summary, this innovative research underscores the transformative potential of non-thermal plasma technology in wastewater treatment. With growing interest from various sectors, it is clear that advancements in this field could redefine how industries approach water management.
