RESUMO:

The availability of treated water in rural communities and agricultural properties is a major challenge, since water treatment plants (WTPs) are mostly built in urban centers. In these regions, the use of water from wells, springs, and rivers without proper treatment can pose risks to human health due to microbiological contaminants and heavy metals. In this context, the objective of this work is to develop and validate a low-cost, compact water treatment prototype capable of removing contaminants and producing water that meets the potability standards established by Brazilian legislation. The prototype was developed based on conventional water treatment stages such as flocculation, sedimentation, and disinfection. Flocculators, dosing systems, and multi-layer filters using sand, gravel, and anthracite were constructed, in addition to an oxidation/disinfection system using chlorine. For the validation of the equipment, two operating modes were evaluated: continuous treatment with automatic coagulant dosing via bypass and batch treatment with prior addition of aluminum sulfate to the raw water. The experiments were conducted at the Queima Pé Water Treatment Plant in Tangará da Serra - MT, where different flow rates (300, 400, 600, 900 L/h) were tested and physical-chemical and microbiological water quality parameters were analyzed, according to the limits established by GM/MS Ordinance No. 888/2021. The results show that the system was efficient in removing contaminants, showing a significant reduction in turbidity and elimination of coliforms at all tested flow rates. When comparing the two types of treatment, the batch showed superior performance, keeping all parameters for all tested flow rates within the required standards. In the automatic system, only the flow rate of 300L/h met the potability parameters. The prototype also demonstrated efficiency in removing iron and manganese through oxidation processes followed by filtration. The prototype showed potential for application in small communities and rural properties, being an easy and low-cost alternative for removing contaminants from water.
