MIXER APPLICATIONS


FLOCCULATION – Flocculation is the agglomeration of
colloidal particles into a larger mass call “floc particles”.                                        Portable

Agitation increases the opportunity for particle contact,
improving the flocculation efficiency.                             and gear driven mixers are

FLASH & DYNAMIC IN-LINE – Mixers are used to uniformly
disperse chemicals, such as coagulant aids, chlorine and
sulfur dioxide into the process stream in very short retention
times. These chemicals are added for the purpose of solids
removal, neutralization, odour & colour control.
                                                                                                     HRF

CARBON MAKEUP – Adsorption is the process of removing the
soluble and particulate impurities from the process water by
contacting the process stream with activated carbon.
• Mixers are used to wet-out the dry activated carbon into
  a slurry, then to maintain uniform suspension and finally to
  re-suspend the carbon after periods when the mixer has                                             ST

• Mixer sizing is based on viscosity, which has a very broad
  range, and therefore it is important to know the polymer
  characteristics for each application.
SLUDGE MIXING – Sludge Blending requires agitation to
ensure a homogeneous mixture is obtained from various
sludge sources.
                                                                                                     MB

EQUALIZATION / NEUTRALIZATION – Flow Equalization is the
damping of flow rate and concentration variations so that a
constant or near constant stream is achieved to the plant.
Neutralization is the process of blending acid or caustic into
the waste stream to adjust the pH level of the basin.
• Equalization mixers are used to blend influents from
  various sources to provide a uniform consistency.
