The amount and properties of the sludge produced in wastewater treatment plants depend on the composition of the wastewater, the type of wastewater treatment used and the disposal method applied to the mud. The sludge that occurs during mechanical, biological and chemical treatment methods must be...

The effluent quality of a wastewater treatment plant (WWTP) in Hebei Province met the Class I-A standard of "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants"(GB 18918-2002) (COD≤50 mg/L, TN≤15 mg/L, TP≤0.5 mg/L, NH3-N≤8 mg/L). However, under the guidance of energy...

Mungbean is a key leguminous crop species highly regarded for its nutritious properties. However, soil salinity greatly reduced its growth and yield. Our study investigated whether applying exogenous nitrogen (N) (ammonium nitrate; AN) could improve salinity tolerance in mungbean seedlings by...

Azo dyes and the byproducts of their degradation have the potential to pollute the environment. Natural water bodies experience less sunlight penetration as a result of these effluents being released into rivers and lakes. Because of their hue, the dyes pollute flowers and the aesthetics because...

An acyclic dinuclear metal complex with O4 donor coordination site was prepared and isolated. A polymethacrylate anchored coordination compound turned out to be designed by the combination of azo compound derived from 3-formyl salicylic acid and diazonium salt of 4-aminophenol with methacryloyl...

The complex composition of persistent and resistant contaminants in oil refinery wastewater presents a significant environmental challenge that conventional treatment methods frequently fail to effectively address. Advanced Oxidation Processes (AOPs), specifically the photo-Fenton method, and a deep...

This study investigates the effectiveness of a combined precipitation and oxidation leaching process in reducing high concentrations of sulphides in tannery effluent from the unhairing bath. First, at precipitation process the influence of operational parameters, such as stirring speeds, pH levels...

The presence of dye pollutants in the aquatic environment, apart from causing aesthetic problems, can also cause health problems. Removal of dye pollutants in industrial wastewater can be done using the adsorption method, which is a simple, effective and low-cost process. Fly ash is a solid waste...

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...

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...

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...

The massive use of antibiotics and the consequent antibiotic pollution have become a major risk to river ecosystems, water quality, and human health. In this study, 28 antibiotics were analyzed in the rural-urban river water of Suzhou City, the inflow rivers of Hongze Lake. The total concentration...

In this study, removal of reactive yellow 145 (RY 145) dyestuff by dry biomass of Ureolytic mixed microorganism culture (UMC), existing in domestic wastewater and various industrial wastewater, was studied. Optimum conditions of adsorption efficiency were tested. For this purpose, studies were...

This study used a biosorbent, derived from processed Prosopis juliflora root powder to treat wastewater and remove lead (Pb), cadmium (Cd), and copper (Cu) ions. The biosorption process was influenced by factors including temperature (25 to 65°C), biomass content (1 to 5 g), pH levels (1.0 to 7.0)...

IIntroducing tannic acid from tea leaves waste as a complexing agent of Fe(III) into photo-Fenton process to prevent Fe(OH)3 precipitation at pH 7, and further to increase photo-Fenton activity in the near neutral pH for Pb(II) photo-oxidation is systematically addressed. The photo-Fenton process...

The biosorption of uranium ions was explored through batch studies employing activated biochar derived from Gracilaria Edulis seaweeds. A chemical synthesis approach utilizing concentrated sulfuric acid created and activated the adsorbent material. SEM and FTIR measurements were used to characterize...

In this study, tamarind leaf extract was used to effectively produce silver oxide (AgO) nanoparticles. Crystal violet (CV), Alizarin red (AR), Reactive black (RB), and rhodamine b (Rh B) degradation were examined to evaluate the effectiveness of AgO NPs. XRD patterns, UV-visible spectroscopy...

Healthy water is a concern for the world due to rapid population growth and technological advancement. The entry of heavy metals into water as a result of various activities causes water pollution that has persistent effects. In this study, a specially designed electrodialysis cell was used to...

The purpose of this work is to examine the efficiency of the Electro-Fenton process (Fenton oxidation) for the elimination of amoxicillin from simulated wastewater through response surface methodology (RSM). The effect three operating parameters that were selected for this evaluation were...
