The sewage collection and treatment system are one of the biggest problems of contemporary civilization, likewise, Brazil has a deficit in the proportion of production/collection and treatment, moreover, this senile contributes to the pollution of the environment and the proliferation of diseases, since waste is released in nature in the streets and river beds in regions where there is no sewage network. Based on this problem, this work aims to prospectively survey patents related to devices that present sewage treatment technology. For this purpose, the European Patent Office (ESPACENET) database was used. The prospecting was based on keywords and international classification of patents and resulted in 10796 records, of which 75% refer to IPC C02F9, which encompasses technologies covering the multi-stage treatment of water, waste water or sewage.
