Advanced feed forward coagulation control for phosphorus removal in wastewater

Discover our coagulant dose control system

Compass Automatic Coagulation Control software from PMA uses the on-line measurements of inlet water turbidity and UV-VIS spectral analysis provided by the s::can Spectro::lyser to optimise phosphorus removal from your wastewater.

The key benefits

The award winning Compass coagulation control system has been adapted for wastewater treatment plants. Compass CPR is designed to optimise coagulant dosing to achieve phosphorus removal without breaching metal compliance discharge consents.

Rapid

Proactive response to changing loads.

Constant

Unaffected independent process control.

Performance

Eradicates under-dosing and increases plant performance.

Savings

Eradicates overdosing and decreases operating costs.

Integrating instrumentation and software to meet phosphorus discharge consents

Truly advanced

Compass software works in combination with s::can hardware to maximise phosphorus removal without over dosing coagulant.  By working with PMA, the Compass software is developed for your specific site and uses the power of online UV-Vis spectroscopy to monitor the influent and automatically adjust coagulant dosing, whether aluminium or ferric.

Com::pass CPR predicts the dose required to overcome the total coagulant demand of the influent in real time – measuring the organics, the suspended solids and estimating the phosphorus via a surrogate measurement. Only by measuring the total coagulant demand can a real time control system truly optimise coagulant dosing and ensure compliance.

Automatic coagulation control system for wastewater treatment from PMA

Compass CPR

The chemical phosphate removal (CPR) system is designed for P removal in wastewater treatment. It delivers the optimum dose to meet P discharge targets at the lowest coagulant dose.

Compass CEP

The chemically enhanced pre-treatment (CEP) system is intended for pre-treatment in wastewater treatment. It delivers the best dose to meet performance targets at the lowest coagulant dose.

Automatic coagulation control system for wastewater treatment, designed to optimise coagulant dose and ensure phosphorus and metal discharge consent compliance.

Com::pass CPR calculates the coagulant demand of all the constituents and adds  this to the  dose required for P removal so that overdosing, compliance breaches, and excessive amounts of lab work can be a thing of the past.
