Abstract

This paper present the electronic instrumentation of an unconventional biofiltration system, consisting of three downflow aerobic biofilters to control the inflow/outflow of wastewater and monitoring temperature and color variables. Biofilters are used in the removal of Azo-type dyes, used mainly in denim dyeing, which due to their properties are difficult to degrade and are discharged into river waters. Each biofilter was packaged with different materials, peat and perlite, inoculated with acclimatized sludge, to remove color and organic material. The results achieved were to improve the sample collection and analysis procedure carried out in each of the biofilters, integrating TCS230 color sensors, PT100 temperature sensors, solenoid valves that control the influent supplied to each of the biofilters and the graphical interface developed in LabView responsible for displaying the measurements of the physical variables. The advantage of an automated biofiltration system is to have measurements in real time and useful for other studies of different biofilter packaging. In this case, it was observed that the biofilter packed with perlite peat mixture presented greater removal of color and organic material.
