THE COAGULATION PROCESS

1. CHECKING THE FILTRATE CONTAINER
When the water level reaches the level of the working platform
(item 4 illustration 7), it is time to perform the coagulation
process.
First check that the remaining content of the fi ltrate container
(item 7 illustration 2) is not higher than 25mm (1").
2. COAGULATION
N.B.: IT IS ABSOLUTELY VITAL THAT THE COAGULATION PRO-
CESS IS CARRIED OUT WITH THE GREATEST CARE, SO THAT
LARGE FLOCKS OF COAGULATED PAINT ARE FORMED. OTHER-
WISE THE FILTERS WILL IMMEDIATELY BECOME OBSTRUCTED,
AND CANNOT BE RE-USED.
A: Remove the working platform (item 4 illustration 7).
B: Open the valve for the water agitator (item 5 illustration 7).
C: Add the coagulation powder as recommended by the paint
manufacturer.
D: Stir the powder with a stick for a moment to avoid that it
sinks down to the bottom in lumps.
D: Allow the agitator to run for a few minutes.
E: Stop the agitator occasionally for around 30 seconds since
this improves the coagulation process. The total coagula-
tion time is around 3-4 min, depending on the amount of
powder, the level of contamination, etc.
When this is done, close the valve for the agitator.
3. FILTRATION
Open the drain-valve (item 10 illustration 2) and drain the
wash-basin completely into the fi lter (item 11 illustration 2).
Clean the inside of the wash-basin thoroughly with the clean-
ing brush (i.e. with recycled water), so that any remains of
residual fl ocks are completely drained into the fi lter.
When this is done, close the drain-valve

CHANGING THE FILTER
N.B.: MAKE SURE THAT YOU USE ORIGINAL DRESTER FILTERS,
NR. 8701 (FINE FILTER), AND NR. 8702 (PRIMARY FILTER).
THESE FILTERS HAVE BEEN TESTED AND APPROVED BY THE
PAINT MANUFACTURERS.
The primary fi lter (item 2 illustration 11) collects most of the
coagulated sludge, while the fi ne fi lter (item 1 illustration 11)
collects the fi ner paint particles.
Remove the sludge from the primary fi lter after each coagula-
tion process (once it is completely dry, the sludge is easy to
remove from the fi lter). By doing so the primary fi lter can be
re-used up to 10 times.
The fi ne fi lter will gradually become blocked after trapping the
fi ner paint particles. In general, the fi ne fi lter can be used for
up to 5 coagulation processes. The fi ne fi lter must however be
changed every 1-2 months, otherwise there is a risk that mould
will develop.
N.B.: THE COAGULATION SLUDGE MUST BE HANDLED IN
ACCORDANCE WITH REGULATIONS FROM THE APPROPRIATE
AUTHORITY. INFORMATION FROM THE PAINT SUPPLIER MAY
BE NECESSARY.
