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 cross-section
of a pipe the mixing intensity is virtually homogeneous.
Reaction time is determined by the pipe length and
flowrate 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 one conditions per tank can be maintained.
Generally speaking a pipe flocculator is used where
a coagulant, a flocculant and optionally a chemical
for pH correction are dosed in sequence for the removal
of turbidity and/or COD or precipitants.
The use of a pipe flocculator in combination with
a flotation system can give COD removals to upto 95%
K-Pack Systems has a wide experience in chemical
treatment, particularly in the use and selection of
coagulants and flocculants in combination with a PFR
pipe flocculator. The PFR pipe flocculator is exceptionally
suitable for our latest developments in the non-toxic
bio-degradable coagulants and flocculants range.
