PFR Pipe Flocculator

Coagulation and Flocculation by controlled Turbulence

• The PFR pipe Flocculator is a plug flow reactor in which process such as coagulation, flocculation, demulsification, precipitation and pH control can take place under highly controlled and well defined conditions.
• The above mentioned processes take place under turbulent flow conditions. At the chemical injection points the pipe diameter is adapted to ensure instantaneous mixing of chemicals and wastewater. Through the crosssection of a pipe the mixing intensity is virtually homogeneous. Reaction time is determined by the pipe length and flow rate and based on the exact requirements, no excess is required . In the plug flow reactor the process can be influenced at any time as opposed to tank reactors, where only condition per tank can be maintained.
• Generally speaking a pipe flocculator is used where a coagulant, a flatulent and optionally a chemical for pH correction are dosed in sequence for the remove all of turbidity and / or COD or precipitants.
• The use of a pipe flocculator in combination with a flotation system can give COD removals of up to 95%.
• K-pack Systems has a wide experience in chemical treatment, particularly in the use and selection of coagulants and flocculantsin combination with a PFR pipe flocculator. The PFR pipe flocculator is exceptionally suitable for our latest developments in the non-toxic biodegradable coagulants and flocculants range.
