ABSTRACT
Due to the high incidence of metals, mainly iron and manganese, characteristic of water of the state of Para, it is necessary that the collected water, either surface or subterraneous source, pass through a filtering process to remove these metals and solid particles. The technical teams of the National Health Foundation Water Quality Control Laboratories of Pará and Amazonas developed two handmade systems for water treatment, which major advantages are easiness to use and setup, convenience, and reduction of treatment costs. For removal of metals, PVC filters were developed with zeolite as filter bed, an alumino-silicate mineral with differentiated grain sizes, after pre-oxidation with chlorine. For microbiological disinfection two PVC models were developed for use with chlorine tablets and granules. The results of the tests performed on raw water and treated water have demonstrated high treatment efficiency obtained with the use of such equipment.
