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

Our award winning coagulant dose control system can be used in drinking water and in wastewater treatment. It can be used with any source water type, any coagulant type and any treatment equipment.

Rapid

Instant response time to any changes in conditions.

Constant

Unaffected independent process control.

Performance

Eradicates under-dosing and increases plant performance.

Savings

Eradicates overdosing and decreases operating costs.

Compass Coagulation Control System

Compass is a cutting-edge advanced automatic coagulation control system for water and wastewater treatment, suitable for use with any metal based coagulant.
FEATURED ARTICLE

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 the fully submersible Uv-Vis spectro::lyser to monitor the influent and automatically adjust coagulant dosing, whether aluminium or ferric or both.

Com::pass CPR will automatically control the coagulant dose to achieve effluent phosphate limits by providing a predicted coagulant mass dose output (mg/L) to the plant control system. This needs to be converted to a volumetric dose using the plant flow. The coagulant dose pumps are then controlled to deliver the required volumetric coagulant dose. Alternatively a flow signal can be taken directly into the s::can controller and the dosing system can be controlled directly by the Com::pass package.

Coagulant control solution 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 designed to be fast, responsive save you an annual return on investment of up to 80%.

Com::pass CPR calculates the demand of the other  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.

Immediate response to changing conditions

Reductions in chemical dosing lower coagulant costs and results in reductions in sludge disposal costs. A WWTP with a coagulant purchase and sludge disposal cost of £399,000 per year is likely to achieve in excess of 15% saving or £51,000. This gives a one-year payback for the system.
