Develop wastewater coagulant dosing around the phosphorus-removal duty and the other demand indicated by incoming-water measurements.
Chemical phosphorus removal. Account for the wider demand.
Develop wastewater coagulant dosing around the phosphorus-removal duty and the other demand indicated by incoming-water measurements.
Discuss your applicationStart with the process question
The incoming phosphorus requirement is one part of the chemical demand. Organic and particulate conditions also matter to the process review.

Connect the model
Compass CPR is intended for chemical phosphorus removal, accounting for phosphorus-related and background coagulant demand.
Agree the evidence
Bring phosphorus records, influent data, chemistry, dose limits, downstream evidence and the current control philosophy.
The measurement arrangement and control objective are agreed for the works. Performance is assessed against site evidence.
Separate phosphorus demand from the background demand.
A wastewater dose review needs to account for the phosphorus-removal duty and the other material arriving with the influent. CPR uses the configured measurement and model arrangement to inform that dose calculation. The proposed output is assessed against the works’ phosphorus evidence, chemistry and operating constraints.
Does the controller guarantee a discharge result?
Performance depends on the plant, chemistry, influent and operating conditions. The control objective and acceptance evidence must be agreed for the individual works.
