Degassing
Degassing the bath
fl
uid increases the ultrasound e
ff
ect.
Freshly-
fi
lled
fl
uid or
fl
uid that has remained in the oscillating tank for a longer period of time
must be degassed prior to use. Gases released in the
fl
uid (e.g., oxygen) are reduced through
degassing and the ultrasound e
ff
ect is thus signi
fi
cantly improved.
The cavitation noise changes during degassing, loud degassing noises disappear at the end of the
degassing process, the ultrasonic bath appears to work more quietly.
A lower noise level, however, does not mean a reduction in ultrasonic power. It rather means the
end of the degassing process and an improvement in the ultrasound e
ff
ect.
4.3.2
Disposal of sonication
fl
uids
The working solution is disposed of pursuant to the speci
fi
cations of the product lea
fl
et and
the label. All aqueous preparations of DR H. STAMM GmbH are prepared pursuant to the
regulations of the Washing and Cleansing Agents Act, are biodegradable and may be added to
sewerage as working solutions. Strongly acidic and strongly alkaline
fl
uids are to be previously
neutralised pursuant to technical data sheet speci
fi
cations. The manufacturer speci
fi
cations for the
corresponding preparations are to be observed.
If the solution contains after use substances that are dangerous to water, e.g., oils, heavy
metal compounds, etc., it must be prepared once the limit values are exceeded (removal of
contaminants) or disposed of as special rubbish.
Disinfection and cleaning agents that become contaminated when used are considered "waste
material" pursuant to the Waste Act (AbfG) and may not be taken back by the manufacturer.
In every case, the statutory provisions and regulations of municipal wastewater plants are to be
adhered to. Information is provided by municipal wastewater plants as well as by environmental
