Bacteriology and genotoxicity of some pharmaceutical wastewaters in Nigeria
Wastewaters from two pharmaceutical production processes, cotrimoxazole B wastewater (BWW) and Piriton wastewater (PWW), were examined microbiologically and for physico-chemical parameters. Furthermore, the wastewaters were also screened for genotoxicity using Allium cepa assay to assess the risk associated with the discharge of untreated pharmaceutical wastewaters into the environment. The ...

Vermifilters: a tool for aerobic biological treatment of herbal pharmaceutical wastewater
Herbal pharmaceutical wastewater possesses high chemical oxygen demand (COD) (21,960–26,000 mg/l) and biochemical oxygen demand (BOD) (11,200–15,660 mg/l) and suspended solids (SS) (5,460–7,370 mg/l). It cannot be directly discharged into surface water bodies, due to its highly biodegradable nature. Herbal pharmaceutical wastewater has been treated by using vermifilter, which is an ecosystem ...

Modeling of hospital wastewater pollution by pharmaceuticals: first results of Mediflux study carried out in three French hospitals
A study has been carried out in three French hospitals in order to assess and model the pharmaceutical load in hospital wastewater and its impact in WWTP. This study, called Mediflux, consisted of three successive steps: first, an original prioritization procedure developed in our laboratory enabled us to select a list of relevant molecules from different Anatomical Therapeutic Chemical (ATC) ...

Characteristic numbers of granular activated carbon for the elimination of micropollutants from effluents of municipal wastewater treatment plants
Adsorption on granular activated carbon (GAC) is a promising step to extend existing treatment trains in municipal wastewater treatment plants (WWTPs) and, thus, to reduce the concentration of micropollutants (MPs) (e.g. pharmaceuticals) in wastewater. It is common practice to use characteristic numbers when choosing GAC for a specific application. In this study, characteristic numbers were ...

The determination of pharmaceuticals in wastewater using a recombinant Arxula adeninivorans whole cell biosensor
Abstract An Arxula adeninivorans based microbial biosensor has been developed for the determination of pharmaceuticals and chemicals such as omeprazole, lansoprazole, β-naphtoflavone and methylcholanthrene within 5 h using biochemical detection and 4 h and 10 min using amperometric detection. The biosensor consists of genetically modified A. adeninivorans G1212/YRC102-hAhR-hARNT-phyK (hAhR ...

Removal of phthalates and pharmaceuticals from municipal wastewater by graphene adsorption process
In this work graphene was used for evaluation of its adsorption behavior and performance in removing phthalate esters and pharmaceuticals in municipal wastewater. Di-n-butyl phthalate (DnBP), di-(2-ethylhexyl) phthalate (DEHP), acetaminophen (ACE), caffeine (CAF), cephalexin (CLX), and sulfamethoxazole (SMX) were emerging contaminants (ECs) with detection frequencies over 92% in a one-year ...

Proteomics reliability for micropollutants degradation insight into activated sludge systems
Little information is available on pharmaceutical trace compounds degradation pathways in wastewater. The potential of the proteomics approach has been evaluated to extract information on activated sludge microbial metabolism in degrading a trace concentration of a pharmaceutical compound (ibuprofen). Ibuprofen is one of the most consumed pharmaceuticals, measured in wastewater at very high ...

Laboratory- and full-scale studies on the removal of pharmaceuticals in an aerated constructed wetland: effects of aeration and hydraulic retention time on the removal efficiency and assessment of the aquatic risk
Pharmaceutical residues in wastewater pose a challenge to wastewater treatment technologies. Constructed wetlands (CWs) are common wastewater treatment systems in rural areas and they discharge often in small water courses in which the ecology can be adversely affected by the discharged pharmaceuticals. Hence, there is a need for studies aiming to improve the removal of pharmaceuticals in ...

Occurrence of antibiotics in pharmaceutical industrial wastewater, wastewater treatment plant and sea waters in Tunisia
Antibiotics are among the most commonly used group of pharmaceuticals in human medicine. They can therefore reach surface and groundwater bodies through different routes, such as wastewater treatment plant effluents, surface runoff, or infiltration of water used for agricultural purposes. It is well known that antibiotics pose a significant risk to environmental and human health, even at low ...

Photocatalytic removal of doxycycline from aqueous solution using ZnO nano-particles: a comparison between UV-C and visible light
Zinc oxide nano-particles were synthesized, characterized and used for photocatalytic degradation of doxycycline using UV-C and visible light. Effects of several operational factors including initial pH of antibiotic solution, initial antibiotic concentration and ZnO nano-particles loading amount were investigated. Comparing photocatalytic degradation and mineralization of doxycycline under ...

Activated carbon for the removal of pharmaceutical residues from treated wastewater
Pharmaceutical residues, which pass naturally through the human body into sewage, are in many cases virtually unaffected by conventional wastewater treatment. Accumulated in the environment, however, they can significantly impact aquatic life. The present study indicates that many pharmaceutical residues found in wastewater can be removed with activated carbon in a cost-efficient system that ...

A study on ruthenium-based catalysts for pharmaceutical wastewater treatment
Ruthenium-based catalysts were prepared by a saturation-dip method. Their catalytic activity was evaluated by a catalytic wet oxidation (CWO) process. The ruthenium-based catalysts were used to purify organic pharmaceutical wastewater with high concentration pyridine and pyridine derivatives that have high chemical oxygen demand (COD). In the CWO process, organic pharmaceutical wastewater was ...
