Evaluation of Data Acquisition System for PES Membranes Permeability Analysis in Water Treatment

Abstract:

Wastewater treatment has become a momentous field today. Membrane ultrafiltration processes are booming due to their versatility of use. However, there are limited studies related to the technology of automatic data acquisition systems (DAQ) for the analysis of pore fouling based on the permeability of the membranes. Thus, the objective of this research was to evaluate a DAQ system through its implementation in permeability tests of polyethersulfone (PES) membranes. For this, through the ANOVA-non-replicable method, the repeatability and reproducibility (r & R) of the data obtained from manual measurements (MA) and DAQ system measurements were analyzed. The tests were carried out through scenarios of filtering distilled water (W) and filtering water contaminated with standard foulant (BSA). The results show a percentage of the r & R relationship between 10% and 30%, concluding that the measurement system through the DAQ system is acceptable according to its use.
