Utilização de carvão ativado biológico para o tratamento de água para consumo humano

Abstract

This review article portrays the use of biological activated carbon for drinking water treatment. Biological treatment has applications in the reduction of drinking water instability caused by the presence of low levels of biodegradable organic matter and reduced inorganic compounds. Instability causes deterioration in the quality of drinking water, such as bacterial growth and biofilm formation in the water distribution system. The article discusses the causes and consequences of instability, the measures used for organic matter evaluation, the formation and control mechanisms of biofilms in granular activated carbon and the techniques used for microbiological and biodiversity assessment of biofilms. In addition, it analyzes the integration of biological activated carbon with other processes used for drinking water treatment.
