Automatic Coagulation Control from PMA uses the on-line measurements of inlet water turbidity and UV-VIS spectral analysis provided by the s::can Spectro::lyser to predict the coagulant dose required to achieve treatment aims.
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.
Instant response time to any changes in conditions.
Unaffected independent process control.
Eradicates under-dosing and increases plant performance.
Eradicates overdosing and decreases operating costs.
Com::pass in conjunction with an s::can spectro::lyser accurately and continuously measures the coagulant demand exerted by the other constituents in the wastewater and uses either the output of an existing ortho P analyser or a surrogate parameter for ortho P from the s::can spectro::lyser to calculate the amount of coagulant needed.
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.
The compass coagulant dose control system designed for turbidity removal in drinking water treatment. It provides the best measure to meet filter turbidity targets (e.g. <0.1NTU) at the lowest coagulant dose.
The enhanced organics removal (EOR) system is aimed for any dissolved organics removal in drinking water treatment. It delivers the prime dose to meet filter turbidity objectives and maximise dissolved organics removal at the lowest coagulant dose.
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.
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.
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.
