Online automatic coagulation control systems utilising UV-Vis spectroscopy are the most advanced coagulation control systems available. By utilising absorption at multiple wavelengths, the nature of the natural organic matter (NOM) can be determined in real-time and the appropriate coagulant dose output, whether that be alum, ferric or any other coagulant.
NOM characterisation enables a better understanding of whether the organics in the raw water are hydrophobic or hydrophilic, and an indication of their molecular weight.
An online automatic coagulation control system to minimise filtered water turbidity breakthrough, ensure maximum organics removal and optimise coagulant dosing.
The online coagulation control system for optimising coagulant dosing whilst maximising phosphorus removal.
Achieving reliable automatic coagulation control is something many water companies struggle to maintain in highly variable (flashy) catchment areas. These areas can be at one time or another; typically low in particulates with a moderate to high natural organic matter (NOM) content or vice versa.
Reduced DBP formation potential by utilising multiple UV wavelength analysis for NOM characterisation and effective organics removal.
In 2010, PMA introduced the patented Compass coagulation control system from Lutra (previously H2Ope) to the UK water industry.
There are two general approaches to phosphorus removal in wastewater treatment works. One is to modify activated sludge to maximise phosphorus removal, the second is to use a coagulant such as iron or aluminium, or in some plants, a bit of both might be used.
