https://oarepo.org/index.php/oa/article/view/4286
<p>Today, the spiritual and material heritage, customs, and ethical values of an individual’s identity as a member of a nation are considered essential in forming the spiritual and equitable qualities of the young generation. However, it has been observed that the historical criteria of values created by our ancestors are being lost across many generations. Ultimately, such neglect damages humanistic qualities and spiritual values and hinders the formation of the nation. To eliminate such shortcomings, it is appropriate to know, study, and apply the ethical, spiritual, and cultural values inherited from our ancestors in life.</p>Nuriddinova Gulshoda Olmaskulovna

https://oarepo.org/index.php/oa/article/view/4284
<p>This study presents a novel Advanced Constructed Wetland (ACW) system for efficient wastewater treatment in hot climate regions. The ACW incorporates a unique arrangement of mixed media blocks, including soil, sawdust, zeolite, and biochar, to enhance pollutant removal. The system is designed to achieve high treatment efficiencies for organic matter, nutrients, and emerging contaminants, while minimizing the required footprint. Experimental results demonstrate the effectiveness of the ACW in treating domestic wastewater and septic tank effluent. The system effectively removes organic matter, nutrients, and pharmaceuticals and personal care products (PPCPs). The presence of ammonia-oxidizing archaea and bacteria in the media layers contributes to the conversion of ammonia to nitrogen gas. The ACW system offers a promising solution for sustainable wastewater management in arid and semi-arid regions. Its innovative design and high treatment efficiency make it a valuable addition to the available wastewater treatment technologies.</p>Mr. Aditya Ramesh NannawareProf. P. A. HangargekarProf. D. C.
