Flocculant treatment

A flocculant (ml/h) is metered into the volumetric flow circulated
(m 3 /h) upstream of the filter. The quantity to be added is noted on
the flocculant packaging, e.g. 0.5 ... 1.5 ml per m
capacity.
Assumption: If the circulation capacity of pool X is 100 m
the amount of flocculant to be added is 1.0 ml per m
tion capacity, the flocculant pump must meter 100ml/h of floccu‐
lant. If the circulation volume is reduced in partial load to e.g.
70 m 3 /h, the amount of flocculant added must be automatically
reduced to 70 ml/h.
The following are entered as variables:
Circulation capacity in m
n
Addition of flocculant in ml/h
n
The metering rate of the flocculant pump is calculated from these
two parameters. The flocculant pump is controlled directly via the
CAN bus. It can also be controlled via mA or frequency.
Because small volumes should be metered as continuously as
possible, the DF4 peristaltic pump is very well suited to this task.
