The elimination of selected pharmaceuticals (bezafibrate, clofibric acid, carbamazepine, diclofenac) during drinking water treatment processes was investigated at lab and pilot scale and in real waterworks. No significant removal of pharmaceuticals was observed in batch experiments with sand under natural aerobic and anoxic conditions, thus indicating low sorption properties and high persistenc...

Background & Aims of the Study: In some situation like rainfall seasons raw water become very turbid so it affected the water treatment plant processes and quality of produced water. Treatment of very high turbid water has some concerns like precursors for disinfection by-products and very loading rate of particle on filter's media and consequently increases in water consumptio...

Water is life, and clean-water demand increasing daily as a result of rapid population growth industrial evolution. Nevertheless, due to the inadequate supply availability new water sources, there need for effective, sustainable removal contaminants wastewater reuse. Several treatment approaches that include chemical, physical, biological methods have been thoroughly tested, with being regarded...

The treatment of water from paint spray booths in automobile assembly plants typically involves applications of large quantity of chemicals as coagulants and flocculants. Suspended paint solids are brought to water surface in sludge pits after these chemicals are added. The suspended paint particles are then mechanically collected and removed as sludge for further treatment and disposal. There ...

background: nitrate is an acute and well-known hazardous contaminant, and its contamination of water sources has been a growing concern worldwide in recent years. this study evaluated the feasibility of nitrate removal from water using the traditional coagulants alum and ferric chloride with lower concentrations than those used in the conventional coagulation process. methods: in this research,...

It has long been recognized that thyroid hormone (TH) is essential for normal brain development in both humans and animals, and there is growing evidence that environmental chemicals can disrupt the thyroid system. In the present work, we used a two-hybrid yeast assay to screen for agonistic or antagonistic thyroid receptor (TR) mediated effects in drinking waters. We found no TR agonistic, but...

9 This study investigates the occurrence of all priority substances (n = 41) listed in the 10 Water Framework Directive and additional substances (n = 47) in raw sewage, as well as the 11 removal performance of lamella clarification and biofiltration techniques. Once the efficiency 12 of both types of techniques has been assessed for typical wastewater parameters, the 13 differences in each tec...
