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 Copyright (c) 2024 https://creativecommons.org/licenses/by-nc-nd/4.0 2024-08-08 2024-08-08 10 8 1 4 ABU RAYKHAN BERUNI, A DICTIONARY SCIENTIST https://oarepo.org/index.php/oa/article/view/4285 <p>This article highlights the great contribution of Central Asian encyclopedist Abu Rayhan Beruni to the history of sciences and the scientific heritage of mankind.</p> A.

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 Nannaware Prof. P. A. Hangargekar Prof. D. C.
