WPF Flocculator

In the WPF flocculator, mixing energy for flocculation is obtained by turbulence in the mixing unit and pipe system. A coagulant is dosed to the raw water at the inlet, followed immediately by a mixing unit for thorough blending. The reaction completes in the pipe following the mixing unit.

Coagulation destabilises the polluted matter in the raw water, forming fine particles. To obtain separable particles, a flocculant is then dosed and mixed in a second mixing unit. Floc growth completes in the subsequent pipe section, producing a uniform, ideal floc for separation.

The WPF is characterised by its plug-flow design: retention time is almost uniform and mixing energy is constant across the pipe cross-section. This means all particles receive the same amount of mixing energy for the same duration, resulting in a highly uniform floc with excellent separation characteristics.

The flocculator can be equipped with additional fittings for chemical neutralisation dosing, dissolved air dosing, and inline pH measurement and control with automatic caustic pump regulation.
