Title: ORP(ozone) question
Post by: Kazington on October 16, 2024, 09:41:51 AM

Can someone explain me please how ORP works when ozone is getting dosed and when it’s not. For instance when ORP sensors is placed and turbidity is high (12 NTU) ORP measurement in the water can be around 250mW. While in different vessel of water turbidity is 1 NTU , ORP is 190mW. Isn’t it if turbidity is higher ORP should be lower since there is more things to oxidise.

ORP is 190mW

mW?

Hard to understand what you describe without knowing the setup and the procedure.

ORP Sensors measuring Redox potential, the unit is mV not mW.
I don't think the Nephelometric Turbidity Unit NTU has an relationship with ORP, because turbidity can be caused of inorganic and/or organic compounds.
