A. Inlet; connect the supply line connected to the pressure side of the
pump here.
B. Vortex; suspended particles and sludge are precipitated by centrifugal
and gravity force.
C. Mechanical filtration; dirt particles are captured on the outside of the
filter foam before the water continues on to the entire filter.
D. Biological treatment; by microorganisms depositing on the open pores of
the filter foam (D1) and bio-balls (D2) or bio-cell (D3), depending on the
filter type. The yellow and blue filter foam (D1), with different size and
density creates different water flow rates. High flow zones (blue filter
foam) in which microorganisms convert ammonia to nitrate via
nitrification. Low flow zones (yellow foam) house anaerobic
microorganisms that convert nitrate to nitrogen (denitrification).
Biological cleaning: by the bacteria deposited on bio-balls (D2) or bio-cell
(D3).
E. UV-c irradiation; the water will be briefly exposed to ultraviolet radiation
from the UV-c lamp. This kills floating algae, germs and bacteria, when
the algae die they clump together and can be collected by the filter.
F. Outlet; this is where the return line to the pond or watercourse should
be connected. When the filter is in filter position (the handle (H) points
to Filter), the water will then flow from the filter back to the pond.
CAUTION: The return line must not be more than 1 meter above the
filter. Avoid pipe resistance due to small Ø pipe and too long pipes.
G. Waste water outlet; connect the waste water discharge line here. Waste
water from the filter can simply flow into the garden and serve as
compost for the plants or be directed to the sewer. When the filter is put
in the back-wash position (the handle (H) points to Clean), the dirt will
flow out of the filter with the water.
H. Backwash lever; this can be used to determine whether the pressure
filter is filtering the pond water (Filter position) or backwashing the
pressure filter (Clean position). The position of the lever indicates to
which outlet the water flows.
I. Cleaning indicator, when the filter is too dirty the orange indicator will
come up in the transparent glass. When the orange indicator has come
up the filter needs to be flushed.
J. UV indicator, when the UV lamp is on the indicator will light up blue. If
this does not happen, check the UV timer switch (K), the power plug or
check the UV-c lamp.
K. UV timer switch, allows you to set the time that determines how many
hours the UV-c is on per each 24-hour period. Setting: 24 - 12 - 0 hours.
The UV-c can be turned off during the winter period.
L. Cleaning wringer, the wringer is driven by a strong motor and will start
working when the backwash lever (H) is moved to Clean position. The
wringer takes care of cleaning the filter foam.
Pressure filter commissioning:
(figs. 1 to 4, 6 to 7B and 16 to 19 - pages 3 to 7 and 10 to 13):
