Monitoring of the consumption of new psychoactive substances in wastewater from Athens

Licit and illicit drug use monitoring is an important subject for public health. Almost every substance that people consume is excreted as parent compound and as metabolites via urine and faeces and ends up in the sewage

Gelation of textile effluent by fish scales: An innovation in liquid waste management

AoS. Gelation of textile effluent by fish scales.

Fish wastes (such as heads, bones, skin, scales, fins, and viscera) often might account up to three fourths of the total fish weight and are dumped carelessly into land or sea, resulting in a negative environmental impact.

Wicherhamomyces anomalus biofilm supported on wood husk for chromium wastewater treatment

Toxic heavy metals are harmful pollutants increasingly discharged in the environment by natural and anthropogenic means. Due to its widespread use in industrial processes, chromium presents a significant impact on the surface waters and ecosystem services. Because

Stevensite: an efficient clay to retain tetracycline from wastewater

Stevensite: an efficient clay to retain tetracycline from wastewater. AoS

The tetracycline family of antibiotics are widely used for human therapy and animal feed. However, tetracycline (TC) is considered a contaminant of emerging concern in the environment due to its presence in wastewater effluents, surface waters and

The destruction of endocrine disruptors in wastewater

In Canada, endocrine disruptors are a very topical issue in wastewater effluent quality. We define endocrine disruptors as chemicals that can interfere with the endocrine or hormone systems in wildlife and humans. Results can vary from different

Iodinated trihalomethanes in waters: a new class of toxic disinfection by-products

Disinfection of water supplies started in the early 1900s to reduce risks to public health from pathogenic microorganisms. Chlorination is the most common disinfection practice, achieving effective primary disinfection and sufficient disinfection residual in drinking water distribution.

How engineered nanoparticles are affecting the treatment of wastewater

In recent years, engineered nanoparticles (ENPs) have been incorporated into a variety of consumer products such as technology, cosmetics, pharmaceuticals and clothing to name but a few. ENPs can be defined as intentionally created particles sized 1-100

Flocculation using starch-based flocculants: An efficient pretreatment for purification of the textile dyeing secondary wastewater

China is a major textile manufacturer in the world; as a result, large quantities of dyeing effluents are generated every year in the country. Textile dyeing effluents are distinguished by high levels of chrominance, chemical oxygen demand,

New strategy for the degradation of persistent pollutants in water

An hybrid solid system for the degradation of persistent pollutants was realized by mixing titanium dioxide, silica and an enzyme extracted from soybean hulls. Removal of organic pollutants from urban and industrial wastewaters is one of the

Impact of selected NSAIDs on performances, microbial activity and microbial community in sequencing batch reactors

The non – steroidal anti – inflammatory drugs ( NSAIDs ) are the most commonly used drugs worldwide. Among them, diclofenac ( DCF ), ibuprofen (IBP) and naproxen (NPX) were frequently detected in the environment as the
