The improper disposal of drugs into bodies of water has become a severe environmental and health issue. Biochar synthesized from different agro residues could be a potential material for the adsorption of pollutants in aqueous environments. Nephelium lappaceum seeds were pyrolyzed at 600 °C in a...

The dairy industry is a major food industry that processes raw milk into a variety of products. The milk processing factory produces DWE with soluble organic components, suspended particles, and trace elements. These components degrade, causing cloudiness and odour. Adsorbing total solids (TS) and...

Natural dyes, such as annatto, are widely used in the food and pharmaceutical industries. However, the effluents from annatto dye production pose environmental challenges due to the presence of residual dye components, organic matter, and dissolved inorganic species (chloride and sulfate). This...

An Anaerobic membrane bioreactor (AnMBR) was applied for treating wastewater of a seafood processing factory in Vietnam. However, Chemical Oxygen Demand (COD), Total Phosphorus (TP), and Total Nitrogen (TN) values of the AnMBR effluent were 250.43 mg/l, 19.96 mg/l, and 62.65 mg/l, respectively, and...

Using a baffle reactor to degrade nitrophenol wastewater, with p-nitrophenol as the target pollutant, investigate the effects of nitrophenol concentration, external carbon source concentration, hydraulic retention time, and dissolved oxygen changes on the degradation of p-nitrophenol in the micro...

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...

Biogas is globally recognized as a crucial source of renewable energy. After undergoing proper treatment, the purified form of biogas, known as "biomethane", has the potential to be injected into existing natural gas infrastructure or compressed for use as a vehicle fuel. The principal pollutants...

A mesoporous activated carbon was produced from the Azolla Pinnate (AP) seaweed by two-step chemical activation technique using sulphuric acid as activating agent. The adsorption of Acid Brown (AB) from aqueous solutions is examined using the produced carbon (AP). The produced activated carbon...

In this paper, based on the factors of treatment process, treatment scale, as well as water quality, the level and distribution of electricity consumption, drug consumption, and indirect carbon emission of five typical wastewater treatment plants (WWTPs) were examined. The distribution of...
