Ferric Dosing Control for P removal
Ferric Dosing Control for P removal
(OP)
Does anyone know of a reliable method for controlling ferric dosing for phosphate removal when you have variable phosphate in the influent?
The treatment works in question is a SBR and has been failing to meet its discharge on Total P. The works serves a hotel with a fluctuating population. Ops believe that the high P values in the effluent coincide with dates when high phosphate detergents are discharged from the hotel. At present, ops manually change the dose but this has not been a successful approach. Would it be okay to continuously give a higher than required dose?

Another less expensive option is for the operator to take samples and do a quick colormetric test to monitor phosphate in the influent manually. Then they can change the dose manually on the metering pump to get proper treatment.
Overdosing is an option but probably isn't cost effective.
