Development of an Automated Compact Wastewater Treament Facility in Mapua University Canteen Area with Ph and Dissolved Oxygen Monitoring
Abstract— The lack of proper monitoring of wastewater parameters may result to non-conformance to
effluent regulatory standards. The aim of this study was to fully automate a compact wastewater treatment
with pH and Dissolved Oxygen Concentration monitoring for Mapúa University’s canteen. The wastewater
parameters that were considered were BOD, COD, TSS, and pH level. The prototype was built through the
characterization of the canteen’s effluent by which unit treatment operations performed were formulated.
Furthermore, automation was applied using Programmable Logic Controller (PLC) and was monitored using
Open Platform Communications (OPC)-based Graphical User Interface (GUI). Using t–test on the
prototype’s effluent parameters, it was found that -7.77, -7.74, -8.78 were the resulting t-values for BOD,
COD, and TSS respectively compared to the -1.76 critical value. It was proven in these findings that the
effluent’s wastewater parameters were less than that of the DENR’s effluent standards under DAO 2016-08
pursuant to RA 9275 (Philippine Clean Water Act of 2004). Thus, the prototype was proven capable of
treating the canteen’s wastewater
