Summary: The aim of this study is to develop an automated wastewater treatment system using Moringa oleifera as a natural coagulant to treat the wastewater generated at Technological University of the Philippines-Manila. The study involved the development of a prototype equipped with a programmable logic controller (PLC) to regulate the motors and valves connected to the system. To assess the effectiveness of Moringa Oleifera and the efficiency of prototype, different treatment processes were employed, including mixing, sedimentation, and aeration processes. Additionally, several significant parameters of the wastewater were tested, including pH level, biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total dissolved solids (TDS). The researchers conducted three trials to evaluate the effectiveness of Moringa Oleifera and the efficiency of prototype. According to DENR (2016-08) standard for water quality, the acceptable pH range is 6.0-9.0, the limit for BOD is 50 mg/L, for COD is 100 mg/L, and for TDS is 1200 mg/L. In the first trial, the results were 6.3 for pH, 74.25 for BOD, 185.64 mg/L for COD and 502.56 mg/L for TDS. In the second trial. The results were 7.5 for pH, 40.51 for BOD, 77.91 mg/L for COD and 547.78 mg/L for TDS. Finally, in the third trial, the results were 7.3 for pH, 41.76 for BOD, 75.93 mg/L for COD and 351.79 mg/L for TDS. The BOD and COD in the first trial did not meet the DENR standard, while both the second and third trials met the standard. After getting the results, the researchers calculated the removal efficiency of moringa oleifera for the three trials. The BOD removal efficiencies were 54.78%, 75.33%, and 74.57% respectively; COD removal efficiencies were vi 35.57%, 72.96%, and 73.65% respectively; Lastly, the TDS removal efficiencies were 71%, 68.39%, and 79.79% respectively. Based on the data, the second trial had the highest BOD removal efficiency, while the third trial showed the best results for both COD and TDS removal. Therefore, the application of Moringa Oleifera in wastewater treatment proved effective in both second and third trials.

The aim of this study is to develop an automated wastewater treatment
system using Moringa oleifera as a natural coagulant to treat the wastewater
generated at Technological University of the Philippines-Manila. The study
involved the development of a prototype equipped with a programmable logic
controller (PLC) to regulate the motors and valves connected to the system. To
assess the effectiveness of Moringa Oleifera and the efficiency of prototype,
different treatment processes were employed, including mixing, sedimentation,
and aeration processes. Additionally, several significant parameters of the
wastewater were tested, including pH level, biochemical oxygen demand (BOD),
chemical oxygen demand (COD), and total dissolved solids (TDS). The
researchers conducted three trials to evaluate the effectiveness of Moringa
Oleifera and the efficiency of prototype. According to DENR (2016-08) standard
for water quality, the acceptable pH range is 6.0-9.0, the limit for BOD is 50 mg/L,
for COD is 100 mg/L, and for TDS is 1200 mg/L. In the first trial, the results were
6.3 for pH, 74.25 for BOD, 185.64 mg/L for COD and 502.56 mg/L for TDS. In the
second trial. The results were 7.5 for pH, 40.51 for BOD, 77.91 mg/L for COD and
547.78 mg/L for TDS. Finally, in the third trial, the results were 7.3 for pH, 41.76
for BOD, 75.93 mg/L for COD and 351.79 mg/L for TDS. The BOD and COD in the
first trial did not meet the DENR standard, while both the second and third trials
met the standard. After getting the results, the researchers calculated the removal
efficiency of moringa oleifera for the three trials. The BOD removal efficiencies
were 54.78%, 75.33%, and 74.57% respectively; COD removal efficiencies were

vi
35.57%, 72.96%, and 73.65% respectively; Lastly, the TDS removal efficiencies
were 71%, 68.39%, and 79.79% respectively. Based on the data, the second trial
had the highest BOD removal efficiency, while the third trial showed the best
results for both COD and TDS removal. Therefore, the application of Moringa
Oleifera in wastewater treatment proved effective in both second and third trials.
