Optimization of dissolved air flotation (DAF) in a waste water treatment process of a paper mill

Paper machine effluents are typically clarified using a dissolved air flotation (DAF) system. Before reaching the DAF flotation tank, fibers and water are separated by dual chemical treatment where a coagulant followed by a flocculant are added.

With the help of Mütek lab devices, dosed chemicals can be optimized and furthermore:

Cost savings through optimized chemical dosage
Reliable and stable operation of dissolved air flotation
Quick lab results enable process improvements
