Degassing
Degassing the bath
fl
uid increases the ultrasound effect.
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 dissolved 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.
4.3.2
Disposal of bath
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.
