A study by researchers from the Graduate Program in Environmental Technology and from the Chemical Engineering Program at Unaerp was highlighted in the latest edition of Revista AIDIS de Ingeniería y Ciencias Ambientales: Investigación, desarrollo y practica, published by the Institute of Engineering of the National Autonomous University of Mexico (UNAM) and Inter-American Association of Sanitary and Environmental Engineering (AIDIS).

Developed by professors Marília Vasconcellos Agnesini, Cristina Filomena Pereira Rosa Paschoalato and Reinaldo Pisani Júnior, the work "Assessment of the removal of Diuron in water using complementary technologies associated with the treatment in a complete cycle", aimed to evaluate the removal of the herbicide Diuron, microcontaminant present in surface water.

Professor Marília Agnesini says that the relevance of the work is mainly due to the study of advanced technologies for use in water treatment. "The herbicide we studied was widely used on sugarcane, and because it is a microcontaminant, it could not be removed in a water station through a conventional treatment that is done, which is what we call a complete cycle", explains the researcher.

In this context, the purpose of the study was to associate technologies such as absorption in activated carbon, with a fixed bed column, and the advanced oxidative process, using hydrogen peroxide and ultraviolet light, to the complete cycle, aiming at the treatment of supply water, according to the potability standard.

Professor Cristina Paschoalotto highlights that the development of the study that originated the article published in the scientific journal arose from the need to assign a more sustainable use to the Guarani aquifer, currently used as the only source of supply in the city of Ribeirão Preto. "The importance of the research is the future contribution to water distribution managers so that they can have scientific information to support the correct selection of technology and operational safety to be used in the treatment of water from the Rio Pardo River to be destined for human consumption", complements.
