Military wastewaters are mainly caused by repair and maintenance operations, construction and loading, assembly and packaging in industrial units, and often contain large amounts of inorganic anions, suspended solids, etc. Considering the need to restore and recycle the used water, this research deals with the purification and reduction of the pollution load of military industries&#39; wastewater using the Bit Trap Filter combined with the advanced oxidation method of nano-bubbling.</span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span style="font-family:Calibri,sans-serif"><b><span style="font-family:&quot;Times New Roman&quot;,serif">Materials & Methods:</span></b><span style="font-family:&quot;Times New Roman&quot;,serif"> In this research, the possibility of the wastewater treatment of Zarrin Shahr, Isfahan defense and military industry complex was studied. TDS, BOD, and COD factors were measured in wastewater samples. Then, they were affected by the pure oxygen nano-bubbling process in a tank and after that, they entered the Bit Trap Filter, and at the outlet, within ten days, a random sample was taken every 24 hours and evaluated.</span><span lang="AR-SA" dir="RTL" style="font-family:&quot;B Nazanin&quot;"></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span style="font-family:Calibri,sans-serif"><b><span style="font-family:&quot;Times New Roman&quot;,serif">Results:</span></b><span style="font-family:&quot;Times New Roman&quot;,serif"> TDS, BOD, and COD factors were obtained as 4669.67&plusmn;209.62, 91.5&plusmn;75.61, and 285.92&plusmn;18.89 mg/liter respectively in the original wastewater sample. During the testing process and after ten days, the amount of these factors in treated wastewater was reported as 493.27&plusmn;41.50, 3.1&plusmn;26.09, and 4.10&plusmn;1.04 mg/liter respectively.</span><span lang="AR-SA" dir="RTL" style="font-family:&quot;B Nazanin&quot;"></span></span></span></span><br> <b><span style="font-size:11.0pt"><span style="line-height:107%"><span style="font-family:&quot;Times New Roman&quot;,serif">Conclusion:</span></span></span></b><span style="font-size:11.0pt"><span style="line-height:107%"><span style="font-family:&quot;Times New Roman&quot;,serif"> In this study, relying on the performance of nano-bubbling and increasing the oxygen capacity of wastewater, as well as the performance of the Bit Trap Filter in removing particles and oxidized and coagulated materials, a clear reduction of TDS, BOD, and COD factors was observed and they decreased by 89.44%, 96.45%, and 98.57% respectively. Based on the obtained results, the effectiveness of the Bit Trap Filter in defense and military industries wastewater treatment is confirmed, and due to the appropriate efficiency and low cost of construction, it is suggested as an efficient and cost-effective system in the field of defense and military industries wastewater treatment.</span></span></span></div> تصفیه فاضلاب, پساب نظامی, ذرات محول, اکسیداسیون, نانوبابلینگ Purification, Military effluent, Dissolved solid, Oxidation, Nano-bubbling 37 44 http://journalaer.com/browse.php?a_code=A-10-2-57&slc_lang=fa&sid=1 Sayyed Mostafa Mir Tabaei سیدمصطفی میرطبایی 10031947532846001097 10031947532846001097 No Sayyed Ali Moezzi سیدعلی معزی moezzi.sayyed.ali@ut.ac.ir 10031947532846001098 10031947532846001098 Yes Arash Javanshir Khoei آرش جوانشیرخوئی 10031947532846001099 10031947532846001099 No Ali Asghar Zomorodkia علی اصغر زمردکیا 10031947532846001100 10031947532846001100 No
