O tipo de tratamento para os efluentes domésticos gerados na empresa é o tratamento físico-químico. Esse processo inclui a incorporação de produtos químicos para ajustar a alcalinidade e o pH, coagulantes, ácido clorídrico, soda, polímeros, carvão ativado e outros. O processo de sedimentação dos sólidos ocorre nos tanques de decantação, onde os flocos formados por lodo, argila e microorganismos se depositam e são separados.
