cond1=>condition: D 2.4: (TWG skip this
decision).
The COD related to
the amount of substance
to be released into the
environment is < 150
mg/L at WWTP
effluent?|request

cond2=>condition: D 2.5: (TWG skip
this decision).
The substance is not
found in waste water
released to
environment?|request:>doku.php?id=E_D2.5

op1=>operation: The substance is readily biodegradable
not toxic, does not lead to PEC / PNEC
ratio > 1, but the amount released leads
to COD > 150 mg/L at WWTP effluent.|uba_white_blk

op2=>operation: The substance is readily biodegradable
and is released to the environment.|uba_white_blk

op3=>operation: The substance is readily
biodegradable, not toxic for
environment, (does not lead to
PEC/PNEC > 1 in WWT? effluent,
although the substance might be used
in different products / mixtures or
processes, the COD is < 150 mg/L at
WWTP effluent and the substance is
not found in monitoring).
The substance seems not to be a
target substance.|uba_white_blk_grn

e1=>end: Operators: Derive
appropriate measures for
release minimisation
(emission prevention and
control measures).
Process not developed yet
as out of the scope of
HAZBREF|uba_green_red

e2=>end: Operators: Check if
additional measures for
release minimisation are
necessary (emission
prevention and control
measures).
Process not developed yet
as out of the scope of
HAZBREF|uba_green_red

e3=>end: Elimination from waste water
stream by degradation / biological
treatment.
Make sure that your WWTP has
biological treatment and depletion
rate is reached in the WWTP, e.g.
by using adapted micro-organisms.
