ABSTRACT Title: Water Quality Analysis Based on Ozone (O 3 ) Concentration in Drinking Water Supply at the Office Background: Monitoring t he quality of the raw water and treatment unit s is necessary to meet the drinking water needs of the Concentrat ing Division employees of PT Freeport Indonesia (PTFI) . Therefore, disinfection with ozonation implemented by PTFI aim ed at eradicat ing microorganisms, particularly pathogenic bacteria, as well as mak ing processed drinking water healthier because the use of chlorine disinfectants can cause problems , such as the formation of trihalomethanes (THMs) due to inaccurate breakpoint chlorination (BPC) calculation s . This research aims to evaluate the ozone concentration in drinking water supply (PAM) in office buildings OB-1 and OB-2 PTFI Concentrat ing Division in compliance with the Decree of the Minister of Industry and Trade No. 705 of 2003 that states that ozone (O 3 ) levels in drinking water should range from 0.1 to 0.4 mg/L . Method: The observation method was used and conducted from July to October 2021. The concentration of O 3 in the PAM system was measured using a cross-sectional design. In addition, the saturated sampling technique was used since the number of monitoring points was limited to 10, namely distribution points or stations consisting of 5 floors in each building. The Lagrangian method was used to analyze the data and the EPAnet software to obtain a simulation of the concentration of O 3 in drinking water. Result s : The hydraulics and drinking water quality simulations reveal that the O 3 concentration at each node and link varies depending on the drinking water distribution segment. The simulation results show that the residual O 3 concentration at the end of the distribution, such as drinking water reservoirs, ranges from 0.33 to 0.39 mg/L. Furthermore, O 3 concentration can be affected by distance, pH, temperature, and environmental conditions around the pipe. This indicates t he greater the distance between the reservoir and the consumer , the less residual O 3 contained in it, and this can be due to reactions, specifically bulk , and pipe wall reactions. Conclusion : The initial concentration of ozone injected in the disinfection process was 0.50 mg/L, which continue d to change until the drinking water was placed in storage tanks in the OB-1 and OB-2 office buildings of the PTFI Concentrating Division .

ABSTRACT
Title: Water Quality Analysis Based on Ozone (O3) Concentration in Drinking Water Supply at the Office
Background: Monitoring the quality of the raw water and treatment units is necessary to meet the drinking water needs of the Concentrating Division employees of PT Freeport Indonesia (PTFI). Therefore, disinfection with ozonation implemented by PTFI aimed at eradicating microorganisms, particularly pathogenic bacteria, as well as making processed drinking water healthier because the use of chlorine disinfectants can cause problems, such as the formation of trihalomethanes (THMs) due to inaccurate breakpoint chlorination (BPC) calculations. This research aims to evaluate the ozone concentration in drinking water supply (PAM) in office buildings OB-1 and OB-2 PTFI Concentrating Division in compliance with the Decree of the Minister of Industry and Trade No. 705 of 2003 that states that ozone (O3) levels in drinking water should range from 0.1 to 0.4 mg/L.
Method: The observation method was used and conducted from July to October 2021. The concentration of O3 in the PAM system was measured using a cross-sectional design. In addition, the saturated sampling technique was used since the number of monitoring points was limited to 10, namely distribution points or stations consisting of 5 floors in each building. The Lagrangian method was used to analyze the data and the EPAnet software to obtain a simulation of the concentration of O3 in drinking water.
Results: The hydraulics and drinking water quality simulations reveal that the O3 concentration at each node and link varies depending on the drinking water distribution segment. The simulation results show that the residual O3 concentration at the end of the distribution, such as drinking water reservoirs, ranges from 0.33 to 0.39 mg/L. Furthermore, O3 concentration can be affected by distance, pH, temperature, and environmental conditions around the pipe. This indicates the greater the distance between the reservoir and the consumer, the less residual O3 contained in it, and this can be due to reactions, specifically bulk, and pipe wall reactions.
Conclusion: The initial concentration of ozone injected in the disinfection process was 0.50 mg/L, which continued to change until the drinking water was placed in storage tanks in the OB-1 and OB-2 office buildings of the PTFI Concentrating Division. The resulting concentration ranged from 0.33 to 0.39 mg/L, indicating that the drinking water treated at the Drinking Water Treatment Plant (IPAM) met the quality standards.
