This study aims at coupling coal cinder filter with biological process to improve pharmaceutical wastewater quality and reduce the disposal cost. In the coal cinder filter, the removal efficiencies of COD, BOD(5), SS and color were 90+/-2%, 72+/-2%, 95+/-2% and 80+/-2%, respectively. The results attribute to the big specific surface area and strong adsorption ability. Coal cinder filter removes...

The present study focused on the evaluation of a nonspecific synergistic effect of biogenic silver nanoparticles (AgNPs) in combination with biosurfactants against environmental bacteria and fungi. The AgNPs were synthesized in the culture supernatants of the biosurfactant producer Bacillus subtilis grown in brewery effluent, molasses or Luria-Bertani media. Antibacterial activities were tested...

Industrial discharge of active pharmaceutical ingredients (APIs) into the environment in some middle- and low-income countries is not sufficiently regulated. The phytotoxicity of metronidazole (FLAGYL)-one of the most commonly used over the counter (OTC) antibiotics, to soybean (Glycine max) is investigated. Relative growth rate (RGR) expressed in gram per gram per day (gg-1d-1) was applied to ...

Phenolic derivatives are used as raw materials in textiles, pulp and paper, petrochemical, pharmaceutical, oil-refineries and leather industries. These heterocyclic aromatic chemicals are among the most frequently found pollutants in industrial effluents. Since these compounds are toxic either through ingestion, inhalation or contact even at low concentrations, biodegradation of the effluent is...

The occurrence of 12 selected pharmaceutical compounds and pharmaceutical compound metabolites in sewage treatment works (STW) effluents and surface waters was investigated. The substances selected for the monitoring programme were identified by a risk ranking procedure to identify those substances with the greatest potential to pose a risk to the aquatic environment. STW final effluent and sur...

UNLABELLED BACKGROUND The fate of 14 antidepressants along with their respective N-desmethyl metabolites and the anticonvulsive drug carbamazepine was examined in a primary sewage treatment plant (STP) and following advanced treatments with ozone (O3). The concentrations of each pharmaceutical compound were determined in raw sewage, effluent and sewage sludge samples by LC-MS/MS analysis. Th...

It is generally accepted that the main route for human pharmaceuticals to the aquatic environment is via sewage treatment plants receiving wastewater from households and hospitals. We have analysed pharmaceuticals in the effluent from a wastewater treatment plant serving about 90 bulk drug manufacturers in Patancheru, near Hyderabad, India--a major production site of generic drugs for the world...

The present study was conceptualized to evaluate the heavy metal absorbing potential of microbes isolated from paper industry effluent. The effluent was used as the source sample, after screening morpho-metrically ten strains were cultured and sub cultured to achieve the pure discrete colonies. Out of ten discrete colonies two were found to have the heavy metal absorbing ability. These two bact...
