4.4.1
Degassing
Degassing the sonication
fl
uid increases the ultrasound effect.
Freshly
fi
lled-in
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 effect 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 effect.
4.4.2
Disposal of sonication
fl
uids
The working solution is disposed of pursuant to the speci
fi
cations in the product lea
fl
et and the
label supplied by the manufacturer of the preparations employed. All aqueous preparations made
by DR H. STAMM GmbH are prepared pursuant to the regulations of the German Washing and
Cleansing Agents Act, are biodegradable and as working solutions may be disposed of in the
wastewater. Strongly acidic and strongly alkaline
fl
uids are to be previously neutralised pursuant
to technical data sheet speci
fi
cations. The manufacturer’s speci
fi
cations for the respective
preparations should be observed.
During cleaning, materials hazardous to water such as oils, heavy metal compounds, etc.,
depending on the type of contamination, may enter the working solution. If the limit values are
exceeded, the working solution must be reconditioned (removal of contaminants) or be disposed
of as toxic waste.
Disinfection and cleaning agents that become contaminated when used are considered
“waste material” pursuant to the German Waste Act (AbfG) and may not be taken back by the
manufacturer. In other countries, the relevant supplementary/divergent national regulations should
be taken into account.
In every case, the statutory provisions and regulations of municipal wastewater plants must be
adhered to. Information is provided by municipal wastewater plants as well as by environmental
agencies.
