The scarcity of water resources on the planet reveals the concern of engineering in solutions to the problem of water treatment. The use of alternative techniques such as wetlands is an innovative option with a great future for the environment. This work was supported by UNICAMP to study the efficiency of removing heavy metals and other chemical elements present in domestic sewage from a system installed at the Faculty of Agricultural Engineering (FEAGRI) at UNICAMP, where two different species of macrophytes were used: Typha sp and Eleocharis sp for treatment in two wetland cells. The analyzes were carried out using the synchrotron radiation technique at the National Synchrotron Light Laboratory (LNLS) in Campinas. The technique made it possible to detect 8 chemical elements present in higher concentrations in sewage, in a study over 16 weeks in 2023. The elements obtained were: phosphorus (P); sulfur (S); chlorine (Cl); potassium (K); chromium (Cr); manganese (Mn); iron (Fe) and zinc (Zn). The efficiency percentage, for example, for phosphorus in the cell with the macrophyte Eleocharis sp was 71.04%, while in the cell with Typha sp, the performance for the same chemical element was 23.20%.
