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...

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...

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...

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...

In response to the growing demand for eco-friendly and efficient catalysts in wastewater treatment, this study introduces a novel, biosynthesized silver nanoparticle (AgNP) using leaf extract from Lawsonia inermis, a widely available plant. We employed a unique concentration mixture of 0.015 mg/mL...

Landfill facilities and organic waste treatment plants typically are known sources of odour pollution, such as gaseous NH3, among others. In this work, the removal of gaseous NH3 released from a composting line of a mechanical and biological treatment plant of undifferentiated municipal solid waste...

Over the past few decades, pharmaceuticals have contaminated the marine ecosystem. The entry of prescription medications into the environment, their underlying causes and problems, and effective methods for treating such contaminated water are all evaluated in this study. Adsorption is becoming a...

Clean water and its requirement are one of the emerging needs in recent days. Water pollution creates more amount of toxic nature to the clean water and it increases the accumulation of poisonous contaminants in the water sources. Heavy metal ions are the type of toxic pollutant released from...

In this work, copper oxides (CuO) and zinc oxide (ZnO) nanoparticles were synthesized using Abelmoschus esculentus (A. esculentus) leaves extract by hydrothermal method and subsequently employed for degrading recalcitrant pesticide imidacloprid (IMI). The CuO and ZnO nanoparticles were characterized...

Compared with free bacteria, immobilized bacteria have a higher oil degradation rate, making them highly promising for the bioremediation of offshore oil pollution. In our study, preparation conditions of modified Enteromorpha-immobilized bacterial agent were optimized by response surface method. A...

Chlorella microbial fuel cells may be an alternative technology for wastewater treatment. Using microalgae and activated sludge as raw materials, a C-MFCs was established, and the effects of different nitrogen and phosphorus ratios in the influent on the electrochemical performance of C-MFCs and the...

Hazardous metal chromium is used extensively in many different industrial processes and is commonly found in industrial effluents. Hazardous pollutants such inorganic anions, metal ions, synthetic xenobiotics, and others have contaminated ground and surface waters in India and other parts of the...

The management of water pollution has been one of the main problems as people pay more and more attention in the current society to the preservation and repair of the natural environment. In this paper, natural montmorillonite was modified with starch as well as lanthanum chloride. The removal...

With an estimated volume of 162 thousand metric tonnes in 2020, India is the world's largest producer of tamarind. The country is home to a number of tamarind species, and production is spread out across the country. Farmers and agro-industries continue to encounter numerous challenges in the...

This goal of this study was to evaluate the effectiveness of a new coagulant extract from pumpkin seeds (PSC) for removing turbidity and organic compounds from different natural surface waters. Two design experiment methods, namely central composite design (CCD) and response surface methodology (RSM...
