Abstract
Filters used in wastewater treatment have the function of capturing solids, microorganisms and chemical compounds, contributing to the improvement of water quality and promoting its sustainability. Among the main filters are sand filters, used because of their low cost and effectiveness in removing suspended solids and reducing turbidity, taking advantage of biological, physical and chemical processes for water treatment. Activated carbon filters, available in granular (GAC) and powdered (PAC) forms, offer high adsorption capacity for specific chemical contaminants and are common in the final stages of water treatment in industrial plants. Membrane filters, which include microfiltration, ultrafiltration, nanofiltration and reverse osmosis, stand out for their efficiency in removing fine particles, microorganisms and salts, but require higher investment and maintenance. Gravel filters, ideal for their accessibility and capacity to remove basic contaminants through physical and biological processes. Sand and gravel filters are viable options for basic treatments, while activated carbon and membranes are reserved for advanced processes where high quality standards are required.
