ORP Management in Wastewater as an Indicator of Process Efficiency
-
Description
-
Oxidation-reduction potential (ORP) is increasingly utilized in municipal wastewater treatment to monitor biological processes that affect water quality. ORP readings, taken via probes submerged in wastewater, provide immediate data indicating the efficiency of treatment processes such as nitrification, denitrification, and phosphorus removal. Different ORP ranges correspond to specific reactions: nitrification occurs at +100 to +350 mV, while denitrification and biological phosphorus removal occur within +50 to -50 mV and +25 to +250 mV, respectively. By maintaining optimal ORP levels, operators can prevent malodors and undesirable biological growth, enhancing overall treatment effectiveness.
