Remo？？o de diclofenaco, ibuprofeno, naproxeno e paracetamol em filtro ecológico seguido por filtro de carv？o granular biologicamente ativado

the ecological filter represents a promising treatment technology, because this doesn't require the application of chemicals and is efficient. in it, is between living beings the relationship of the food chain. initially an aqueous matrix was added to four drugs (diclofenac, naproxen, ibuprofen and paracetamol), and subsequently analyzed by high performance liquid chromatography to evaluate the removal of these compounds by ecological filter followed by granular activated carbon filter biologically active. the pharmacological compounds and parameters such as turbity, total and fecal coliforms, apparent color and true color were measured to evaluate the effectiveness of filters. there was removal of the drugs applied and the parameters measured. the percentages of removal were 97,43% of diclofenaco,85,03% of ibuprofen, 94,11% of naproxen and 84,07% of paracetamol.
