Product description
Biotec 30 is a multi-zone filter for large ponds up to 130 m³, or up
to 65 m³ for fish ponds. The arrangement of brushes, mats and
sponges in this filter accelerates the filtration of larger dirt parti-
cles. This allows the microorganisms to break down harmful nu-
trients more effectively.
Assembly
In order to use the Biotec filter, it is necessary to fit the connect-
ing parts and washers. See Illustrations 1-4 at the end.
1. Inlet (Illustration 1):
Attach matching gasket (2) to the stepped hose adapter 1½"
(1) then screw together with inlet nozzle (3) from the inside.
Attach air hose (4). Fit matching gasket 2"(6) and reducer (7)
to the 2” stepped hose adapter 2" (5) and fit in the same way
as the 1½” stepped hose adapter. Caution: Slit opening of
inlet nozzle must point downwards!
2. Dirt outlet (Illustration 1):
Attach matching gasket (9) to outlet (8) and push into hole at
bottom of container. Screw tightly into place from the inside
using enclosed screws (10).
3. Clear water outlet (Illustration 2):
Push thread nipple (11) with washer (12) and matching gasket
1" (13) through the hole of the container from the inside. Fit a
gasket from the outside, too, and screw on ball cock (14).
4. Outlet (Illustration 2):
Insert seal ring (15) into borehole and push in outlet pipe DN
100 x 150 (16).The sealing lip must point to the inside. The
outlet pipe DN 100 x1 50 can be extended with 2 enclosed
pipes DN 100 x 500 (37).
5. Bitron 15/12 (Illustration 3):
In order to connect the Bitron 15/25, another 2 gaskets per
Bitron outlet have to be fitted (included in Biotec 30 inlet set) in
addition to the extension components included with the Bitron
15/25. Put the gasket 1½" (2) on the Bitron outlet and then fit
the spacer ring (17) and O-ring 48 x 4mm (18). Attach Bitron
15/25 at the boreholes in the container and press the O-Ring
48 x 4 (18) against the container wall from the inside. Screw
on inlet nozzle (3).

Directions for use
Start-up
1. Connect pump in pond via a hose to the adapter on the filter.
•Cut adapter to right size to fit hose
•If necessary, briefly dip ends of hose in boiling water
before attaching
•Lay hose without twists and so that it cannot be stepped on
•Affix hose clips to ends of hose
2. Lay domestic DN 100 drainage pipes from the filter outlet to
the pond inlet with a gradient of at least 1%. If the pipes are
not UV-resistant, possibly cover them with earth.Extend the
wastewater outlet with DN 70 drainage pipes.
3. Switch on pump and test water flow.
Special guidelines:
•The hose connections on the filter must be fitted with care.
•The filter must never overflow (e.g. due to a clogged drain).
Danger of pond emptying.
•The filter system is a biological system and requires a few
weeks after initial installation to become fully effective.
•The filter should be in permanent operation and never run dry.
Installation
Place filter on a firm level base. If using a UVC lamp, leave a gap
of at least 2 m to the water. You might wish to do this in any
case, should you wish to add a Bitron later on.
6. Bitron 36/72 (Illustration 4)
Put one 48 x 4 O-ring (18) on each Bitron outlet. Attach the
Bitron 36/72 through the boreholes in the container and press
a 48 x 4 O-ring (18) against the container wall from the inside
for each attachment. Screw the inlet nozzle (3) on. See also the
instructions for the Bitron 36/72.
Maintenance and cleaning (Illustration 5)
Biotec filters are maintenance-free, however they should be
cleaned whenever necessary.
To drain off the wastewater, pull out the slide valve (19). This lets
the wastewater drain away freely. If necessary, some clean water
can be drained via the clear water outlet (14). This significantly
reduces the amount of dirty water.

1. Clean the filter brushes (20) as often as possible. To do this,
rinse the brush frame. This can be done inside or outside the
container. The bottom end of the brushes should rest on the
black filter mat.(Illustration 6)
2. Only clean the filter mats (21) when necessary. They become
more effective as bacterial growth increases. The filter mats
can also be cleaned inside or outside the container. The filter
mats 1-5 must be fitted in the correct order. Filter mat # 5 has
a sealing lip. This must rest on the intermediate base (25).
(Illustration 6)
3. Clean the blue (22) and red (23) sponges when the water
through-flow is no longer adequate and the water level rises
above the sponges. The sponge holders can be easily pulled
out of the intermediate base (25) to facilitate cleaning.
Only rinse filter elements with water. Do not use chemical
cleansing agents!
