Occurrence and Reduction of Emerging Contaminants in Sludge

Emerging contaminants consist of a wide range of anthropogenic as well as natural substances which include pharmaceuticals,personal care products, steroid hormones, industrial chemicals, pesticides and many other emerging compounds. Since theirconcentrations vary from a few ng/L to several μg/L, they may also be called as micropollutants. There has been a growingawareness and concern about these chemicals for the last few decades since many of these are known to have toxic, carcinogenic orendocrine disrupting properties.Limited removal of most of these compounds during wastewater treatment processes, cause them enter the water resources andmove up the food chain. The hydrophobic nature of many of these compounds promote their accumulation in organic phases includingsludge during wastewater treatment plants. This creates extra concern due to the beneficial use of sewage sludge in soil in manycountries around the World. The chemically complex nature of many micropollutants make them hard to degrade during conventionalwastewater and sludge treatment systems. Besides, the presence of wide variety of chemicals indicate that one single treatment type(aerobic or anaerobic) may not be enough to effectively remove them from wastewater and sludge.The way wastewater treatment plants and sludge treatment units operated act as an important determinant on the final concentrationof these chemicals. This talk will highlight the occurrence of emerging contaminants in wastewater and sludge and the governingfactors to reduce them from wastewater effluents and from sludge.

Occurrence, fate and removal of endocrine disrupting compounds (EDCs) in Turkish wastewater treatment plants
KOMESLİ, Okan Tarık; Muz, M.; Ak, M. S.; BAKIRDERE, Sezgin; Gökçay, Celal Ferdi (2015-10-01)
Endocrine disrupting compounds, EDCs, are somewhat recently recognized pollutants which are often classed within 'emerging micropollutants' in the environment jargon. These compounds are known to interfere with the delicate balance of the endocrine system of animals and man, causing variety of undesirable outcomes. Their sources in natural waters are the domestic and industrial effluents. The main cause of concern with EDCs is their tendency to accumulate in fish causing gender shifts and reduced fecundity....
Biological Treatment of Micropollutants
Bayramoğlu, Tuba Hande (IWA Publishing, 2010-01-01)
Municipal wastewater is the main source of micropollutants which are present in the household products (detergents, cosmetics and paints) and natural excretion of humans (drugs and metabolites, synthetic hormones) (Bruchet et al., 2002; Bicchi et al., 2009). After their use, pharmaceuticals are excreted intact and/or as metabolites with feces and urine; thus are introduced directly into wastewater (Lo¨ffler et al., 2005). New sanitation concepts where wastewater streams are separated and treated according t...
Formation and characterization of food grade liposome systems
Güner, Selen; Öztop, Halil Mecit; Department of Food Engineering (2015)
Liposomes are double-layered spherical vesicles made up of polar lipids and could be used in pharmaceutical, personal care, chemical and food industries to encapsulate both hydrophobic and hydrophilic compounds. Being biodegradable, biocompatible not having any toxic effects and having the ability to release the active agents when desired make these systems advantageous for many applications. The main natural sources used for liposome formation are egg and soy. In this study, egg and soy lecithin with highe...
Emerging Contaminants
Sanin, Faika Dilek (2017-07-13)
Many of the products and drugs used commonly contain chemical components which may persist through sewage treatment works (STW) and eventually enter the aquatic environment as parent compounds, metabolites, or transformation products. Pharmaceuticals and personal care products (PPCPs) and other emerging contaminants (ECs) have been detected in waters (typically ng/L) as well as more recently bound to sediment and plastic particles (typically ng/g). Despite significant advancement of knowledge since the late...
Bioactive thiazole and benzothiazole derivatives
Rouf, Abdul; Tanyeli, Cihangir (2015-06-05)
The heterocycles are the versatile compounds existing in almost all natural products and synthetic organic compounds, usually associated with one or the other biological activity. Among the heterocycles the thiazoles and benzothiazoles occupy a prominent position. They possess a broad range of biological activities and are found in many potent biologically active molecules and drugs such as vitamin thiamine, sulfathiazol (antimicrobial drug), ritonavir (antiretroviral drug), abafungin (antifungal drug) and ...
