II. Product description
2.1.4.2 Solid particles
A titration curve for an aqueous suspension of particles
is shown in Fig. 2-4.
Here the titration curve is nearly linear, because all solid
particles contribute toward the creation of a streaming
potential.
Fig. 2-4 Suspended solids
2.1.4.3 Heterogeneous stock systems
A titration curve of heterogeneous systems (colloids,
dissolved material, solid particles, fibres etc.) is shown
in Fig. 2-5.
After dropping sharply at the beginning, the curve flat-
tens out toward the end of titration.
The buffer effect around the point of zero charge may
be caused by the fact that titrant is included in the fibres.

2.2 Applications
Papermaking
- Improved machine running by controlling anionic
trash
- Improved retention control
- Enhanced chemical performance
- Stable paper quality
Effluent treatment
- Optimized chemicals by controlled flocculant dosa-
ges
- Increased dry content of sludges through improved
dewatering
- Exact identification of the demulsification point of
emulsions and cooling lubricants
- Optimized selection of flocculants
Filler/ pigment processing
- Determination of the optimum dispersed condition
and of dispersant dosages
- Selective flocculation of particles after identification
of the isoelectric point
Other applications
An identification of charges is also very important for
producers from the beverage and food industry and in
the ceramics, dyes, cosmetics and pharmaceuticals
sectors. In all these areas the Mütek™ PCD-05 is fin-
ding increasing application.
