Oxidation-Reduction Potential (ORP) plays a crucial role in wastewater treatment by measuring the system's ability to oxidize or reduce substances. A good ORP level typically ranges between +200 to +300 mV for oxidation processes and -200 to -300 mV for reduction processes. Maintaining optimal ORP levels ensures efficient removal of contaminants and supports microbial activity in biol... https://www.watertreatmentplants.in/what-is-good-orp-level-in-wastewater-treatment/
