Study of the Filtration Run of Industrial Effluent Using Sand Filters at Different Filtration Rates on a Bench Scale

Abstract

Objective – The main objective of this research is to evaluate the physical filtration process using sand filters on a bench scale for the treatment of industrial effluent generated in the CIP (Clean in Place) process of a brewery.

Methodology –  Experimental research on a bench scale with a quantitative approach. The experimental scientific method was applied to evaluate sand filters in the treatment of brewery CIP effluents, analyzing color, turbidity, and pH according to AWWA (2012) standards.

Originality/Relevance – The study addresses a theoretical gap regarding the use of sand filtration for specific industrial effluents. It stands out for proposing a simple, low-cost, and sustainable technology aligned with SDGs 6 and 12.

Results – Filtration achieved reductions greater than 50% in color and turbidity while maintaining stable pH. Clogging increased removal efficiency, demonstrating the good performance of the system.

Theoretical/Methodological Contributions – Deepens the understanding of the filtration run and clogging in granular media, presenting a reproducible experimental model for future design applications.

Social and Environmental Contributions – Promotes water reuse and sustainable practices in the brewing industry, contributing to the reduction of potable water consumption and the mitigation of environmental impacts.
