Spanish water treatment plant solves purity problems
7 Apr 2010
Barcelona, Spain – A new water treatment plant near Barcelona and designed by Severn Trent Services-Apliclor and the Puig-reig (Spain) City Council is solving a long-standing problem of elevated iron and manganese levels in the city’s drinking water. The plant is also minimising hazardous compounds that are formed by the reaction of chlorine with organic matter.
The plant was constructed in accordance with the Spanish government’s Plan E economic stimulus plan. Water distribution and treatment services company SOREA, part of Agbar, was the general contractor for the project worth Euro750,000.
The treatment plant covers 1,500 m2 and treats up to 80 m3/hr to provide water for the 4,000 inhabitants of Puig-reig. The facility was dedicated by the Mayor of Puig-Reig and local government representatives. The facility, which comprises pre-oxidation, coagulation/flocculation, filtration and disinfection systems improves the quality of the water by removing iron and manganese.
Severn Trent Services-Apliclor’s Aquadiox chlorine dioxide generating system serves as the pre-oxidation process as an alternative to the use of chlorine. This is said to minimise trihalomethanes, hazardous compounds that are generated by the reaction of chlorine and organic matter during the water treatment process.
