Flocculation is apparently protective for the FLO1 + cells, which are shielded from certain stresses ( ethanol, for example ).
42.
The addition of nutrients other than sugars has been demonstrated not to reverse flocculation ( Soares et al ., 2004 ).
43.
Another purpose of this titration is determination of the optimum dose of surfactant for achieving stabilization or flocculation of a heterogeneous system.
44.
Typical operations to achieve this are filtration, centrifugation, sedimentation, precipitation, flocculation, electro-precipitation, and gravity settling.
45.
Flocculation is thus the initial step leading to further ageing of the emulsion ( droplet coalescence and the ultimate separation of the phases ).
46.
Finally, the particles are subjected to a repulsive force in order to keep them separated from one another and lowers the likelihood of flocculation.
47.
Although flocculation followed by filtration has been suggested as best practice this is rarely practicable without the ability to carefully control pH and settling conditions.
48.
Other methods for household water treatment and safe storage exist ( e . g ., chlorination ) different filtration procedures or flocculation / disinfection.
49.
The water treatment plants used the technologies of " pre-chlorination, rapid mix, flocculation, sedimentation, filtration and chlorine disinfection ".
50.
A fourth factor is the degree to which the plume's material clumps together to form larger particles, a process known as flocculation.
