The usual solution to this is to add another chemical called a flocculent.

A floccule (floc) will form from a precipitated aggregation of material with a cloudy appearance (Figure 1).

Flocculation is the agglomeration of destabilized particles into microfloc and after into bulky floccules which can be settled called floc.

The water receives a reagent intended to cause the agglomeration of these particles in suspension into flocculent aggregates, the whole of which forms a mass called “floc”.

Floc may be extracted from the floc settling pit (86) by a floc extraction pump (90).

A floc drawoff pipe (98) is provided for drawoff flocs over the lower outflow prevention plate (40).

Care must be taken to prevent the breaking up of floc, particularly colour floc;

The color of the adhesive is at least similar or substantially similar in color to the flock fibers in the corresponding flock region.

Further, each flock region is of a different color relative to an adjacent flock region to form a patterned, multicolored design.

Each flock region is defined by a plurality of flock fibers that are substantially the same in color and are substantially free of light dispersants, such as titanium dioxide.

The invention relates to a flock separating apparatus, comprising an electrolytic cell (2) fitted with iron electrodes and a separating tank (3), wherein the flock is carried upwards by a hydrogen gas produced in electrolysis.

An appliqué includes a substrate or carrier, flock derived from recycled material, ink in the flock, and an adhesive for adhering the appliqué to a fabric.

Each of the plurality of adhesive regions corresponds to a flock region and includes a colored adhesive.

The flock coated grip provides good mechanical engagement with a user's hand and even better mechanical engagement if used with a glove or attachment pad also having an electrostatically flock coated surface.
