    The research aimed to produce activated charcoal from açaí seeds for water treatment in the riverside community of Membeca, in the municipality of Santarém, state of Pará. The study was conducted in two phases: in the first, açaí seeds were collected, activated charcoal was produced using chemical methods, and a handmade filter was elaborated. In the second phase, parameters such as suspended solids, turbidity, apparent color, total coliforms, Escherichia Coli, pH, temperature, aluminum, iron, nitrate, manganese, mercury, and lead were analyzed. The results showed that the use of activated charcoal under the experimental conditions did not meet the standards for water quality for human consumption, although it was effective in reducing some parameters, such as manganese, nitrate, and lead.
