Water intake
Universal connection (3 /4
”
– 1 1/2
”
) for the pump supply hose
in the pond.
"
UVC-radiation
The pond water, which has already undergone preliminary
treatment, is subjected to short wave UVC-light (ultraviolet
rays). During this process, the algal growth is reduced and
germs which cause disease in fish ponds are killed.
§
Mechanical filtering
Dirt in the pond water is retained mechanically by the large
outer surface of the filter sponges in the filter.
$
Biological treatment
The biological pond water treatment takes place in two
different areas of the filter:
•
Filter sponges / bio-surface elements :
This promotes the growth of micro-organisms which guarantee
the conversion of ammonia into nitrate via nitrite (nitrification).
•
Lava stone :
This supports the growth of anaerobic micro-organisms which
promote denitrication (reduction of nitrate to nitrogen).
