Plant fault
Probable cause
Repair
The purification
efficiency of
the plant is
unsatisfactory
Most of the faults
mentioned above lead to
reduced purification
efficiency
In the interest of the
environment, you should contact
your service company
immediately to ensure the
proper operation of the plant
NOTE: The plant
achieves full
purification
efficiency after a
start-up period,
which, when
heavily
underloaded or at
low temperatures
< 12°C, may even
last for several
months. If
necessary, SBR
plants can be
injected
with suitable
activated Sludge
from a different
fully biological
small wastewater
treatment plant to
shorten the start-
up time
The following
causes also lead to
insufficient outflow
values:
a. Introduction of
cleaning agents or
disinfectants or other
prohibited substances
b. Insufficient air intake
and/or treatment tank
aeration and
deaeration
c. Assembly error
d. Container not sealed
e. Inflow of external
water (e.g.rain water)
f. Sludge not removed
g. Incorrect setting for
inhabitant values
h. Plant disconnected
from the mains supply
for a long time
