Researchers at the Consejo Superior de Investigaciones Científicas (CSIC) and Institut Català de Recerca de L'Aigua have developed a new method that allows simultaneous detection of up to 75 drugs in the water. The system, tested the waters of the Ebro basin during the years 2006 and 2007, addresses the need to monitor the presence of drugs in wastewater, according to the new Water Framework Directive of the European Union.

Specifically, researchers have analyzed the new method of water purification of seven of the Ebro basin during 2006 and 2007. The results show that the anti-inflammatory drugs are present, lipid regulators, beta blockers, antibiotics such as fluoroquinolones, macrolides, sulfamethoxazole and trimethoprim; diuretics such as furosemide and antihypertensive. They also found remains of glibenclamide (for diabetes) and metronidazole. The levels of drugs are recorded in what is considered normal but have found more substances than in previous years, not because the waters are more contaminated, but because now we have a tool that can detect more compounds. In any case, the researchers plan to examine other areas of the Llobregat river and sewage treatment plants closer to Barcelona to complete the study.

The cooling towers are aiming to lower the temperature of the hot water comes from a cooling circuit through the heat and mass transfer to the air that circulates inside the tower. To improve the air-water contact, using a fabric called "stuffed." Water enters the tower at the top and spread evenly over the filling using sprayers. Thereby achieving a good contact between water and atmospheric air.

The filler serves to increase the time and area of exchange between water and air. Once the contact between water and air, a constant heat transfer from water to air. This occurs because of two mechanisms: convection heat transfer and the transfer of water vapor from the air, thereby cooling the water due to evaporation.
