Moving Bed Biofilm Reactor (MBBR) technology is applicable for removing organic components and nitrogen from wastewater in the Guheshwori Wastewater Treatment Plant (GWWTP). A lab-scale single-staged aerobic batch MBBR (16L pure volume, 5L active working volume) was designed and initiated using...

Hydrological monitoring in urban regions is crucial to analyze hydrology and manage floods. Nevertheless, monitoring flood overflow in urban areas including the degree of flood overflow is frequently insufficient. Hydrological models' ability to provide early flood warnings is limited by this...

This study aims to establish the effectiveness of nodule bacteria from Sesbania in eliminating nitrate (NO₃) and phosphate (PO₄) in wastewater from the sugarcane industry. The experiment was carried out for 60 days in which the wastewater was availed for treatment and Sesbania plants were modified...

The purpose of our study was to assess the adverse outcomes of exposure to toluene (Tol) on the male reproductive system and to investigate the potential efficacy of Punica granatum juice (PJ) and peel aqueous extract (PAE) against these effects. Rats were divided into the following groups: Control...

This study investigates surface water pollution in two dams in northeastern Algeria: Ourkiss Dam in Oum El Bouaghi Province and Babar Dam in Khenchela Province, over a year (March 2023 to February 2024). The research assesses pollution levels, organic contamination, and nutrient status using several...

Elucidating the mechanism of the correlation between urban spatial agglomeration processes and carbon emission levels can provide valuable scientific underpinnings for town planning under the constraints of low-carbon goals. This study investigates the characteristics of urban spatial agglomeration...

As global climate change intensifies, with frequent extreme weather events, the stability of vegetation is severely threatened. This study (2002–2023) uses NDVI, temperature, and precipitation data, along with methods like pixel binary, trend analysis, and multiple regression residual analysis, to...

The rapid urbanization in China has led to severe agricultural non-point source pollution, threatening sustainable development. This study investigates the impact of new urbanization policies on controlling agricultural non-point source pollution and explores the underlying mechanisms. Utilizing...

Wetlands are among the most important ecosystems in the world, owing to their ecosystem characteristics. Therefore, they offer rich biodiversity in the areas where they are located. However, despite all legal regulations, wetlands are at risk both globally and in Türkiye. This risk is mainly caused...

The influence of land-use patterns on water quality in the Huaihe River Basin was analyzed using the Nemerow index, correlation and multiple linear regression analysis based on the measured data from 62 sampling sites in the Huaihe River Basin (China). In the point buffer zone, a significant...

The Karun River, the longest and highest water flow river in Iran, has experienced heavy and trace metal pollution in recent years. While previous studies have evaluated the water quality of the river, not all sections from north to south have been examined for all metals. To address this gap, a...

Investigating the spatiotemporal heterogeneity of livestock environmental efficiency and its decoupling effect is crucial for fostering the coordinated development of livestock economy and environmental sustainability. This study examines the spatiotemporal distribution, regional gaps, dynamic...

The main purpose of this study is to evaluate the possibility of using a lignocellulosic residue, peanut shells after alkaline activation, as a low-cost adsorbent for the removal of methylene blue dye from aqueous solutions. Adsorption experiments were conducted by varying parameters such as the...

Conventional electrical power systems often prioritize economic gain over environmental protection, which can lead to negative environmental consequences, such as emissions from thermal power plants. In recent years, there has been significant research and investment aimed at addressing the...

In this work, untreated activated carbon (UDP-AC) and activated carbon chemically treated with H₂SO₄ (TDP-AC) were successfully synthesized from date pits, a solid waste material. Characterization was performed on both UDP-AC and TDP-AC, and both samples were used to adsorb methylene blue (MB) dye...
