• Abstract: Sanitary engineering is an important arm in the sustainable development of the planet. To solve the environmental problems generated by the unbridled growth of cities and production and supply systems, this branch of engineering has been studying new methodologies and creating new technologies to combat environmental pollution. One of the most worrying fields of pollution today is with water resources. Well, there is no life without water and with that it becomes important to maintain water bodies on the planet. Faced with this challenge, sanitary engineering has been studying and developing new tools to control the aquatic biome, known as alternative sewage treatment systems. Among the systems that make up this segment is the slow filter system. Slow filters are technologies based on the use of sand and gravel of different dimensions that, when joined in a single chamber, form a system that, through physical-chemical processes, allows the removal of polluting agents from contaminated water. The present research used a pilot system developed at UNICAMP to analyze the parameter related to Biochemical Oxygen Demand (COD). The installed system has two conventional filters, in which there is an additional layer of activated carbon to enhance the purification process. During the study period from July 22 to July 26, 2024, the results achieved in relation to the improvement in the COD parameter were 59.15% and 73.51%. Since the values ​​include slow filters – conventional and with an additional layer of activated carbon, respectively.
