Experiences with the AquaMaster at the Municipality of Oberaegeri, Switzerland

Experiences with the AquaMaster at the Municipality of Oberaegeri, Switzerland

Since July 2013, the raw water of the 3 sources Reservoir Moos has been monitored with 3 measuring systems AquaMaster.

Priorly, only 1 turbidimeter with switching valves was used for all 3 sources.

 

The following parameters have been monitored by the AquaMaster:

  • turbidity
  • pH
  • conductivity
  • Redox/ORP
  • temperature

 

On which criteria did the municipality Oberägeri base their decision for the new measuring systems AquaMaster?

  • Compact system, small footprint.
  • Only 1 water connection is necessary.
  • Modular structure. The system can be expanded with further measuring parameters.
  • High level of certainty as a result of individual monitoring.
  • Simple handling, people on-site can carry out maintenance themselves.

 

Which experiences have been made after 6 months of operation? Mr. Duss, source manager:

  • The 3 systems have been operating without fault.
  • Changes in the water quality have been detected immediately by the measurements. Feeding water into the reservoir is thus automatically controlled.
  • The measured values have been very stable. They have been checked continually by comparative measurements. Since starting operation in July 2013, it has not yet been necessary to calibrate the measuring probes.
  • The maintenance and cleaning effort is minimal and can be carried out by the people on site.

Absorption Measuring Instrument in-line

The ColorPlus measures the colour/absorbance online at up to three different wavelengths in the UV and visible range, also combined. Turbidity can be compensated at the same time by selecting an appropriate wavelength. The modular design of the instrument enables to cover various applications by selecting the most suitable measuring cell. In many cases, a standard housing like e.g. Varivent® is used. Alternatively, custom-specific flow cells in different materials and designs are available. For inspecting the instrument, checking units on the basis of reference filters can easily be inserted. Operation is done intuitive using the intelligent control system SICON via touch screen technology and colour display. Values, graphs, alarm and status messages can be presented. An internal data logger allows recalling and displaying measured data from the last 32 days. A variety of analogue and digital interfaces allows smooth system integration and control.

Absorption Measuring Instrument bypass

The ColorPlus measures the colour/absorbance online at up to three different wavelengths. The bypass measuring cell has been specifically designed for applications within the water industry. Depending on the configuration it allows measuring DOC (UV absorption) and colour (Hazen) simultaneously and to compensate turbidity. Soiling of the flow cell is measured by means of a compensation glass in the interior of the flow cell. The effect of cell soiling is greatly reduced internally; constant and precise measured values are guaranteed. The user is alerted if the cell has to be cleaned. The cover of the flow cell can be opened without tools and allows simple access for cleaning the flow cell. For inspecting the instrument, checking units on the basis of reference filters can easily be inserted. Operation is done intuitive using the intelligent control system SICON via touch screen technology and colour display. Values, graphs, alarm and status messages can be presented. An internal data logger allows recalling and displaying measured data from the last 32 days. A variety of analogue and digital interfaces allows smooth system integration and control.

Ozone meter for gases

The Ozone meter for gases measures the ozone concentration according to standard DIN 19627 and the IOA (International Ozone Association) at a wavelength of 254nm. According to these standards, the extinction coefficient is 3024 l/mol cm. Therefore, the ozone measurement can be regarded as an absolute measurement requiring no calibration with ozone. Special measuring cells with different path-lengths cover measuring ranges for low as well as high concentrations. The concentration readings (e.g. in g/m3) are valid for the pressures and temperatures prevailing during measurement. For the conversion to standard conditions, an external pressure and temperature sensor can be connected to the operating unit, die calculation is then automatically done within the instrument. For inspecting the instrument, checking units on the basis of reference filters can easily be inserted. Operation is done intuitive using the intelligent control system SICON via touch screen technology and colour display. Values, graphs, alarm and status messages can be presented. An internal data logger allows recalling and displaying measured data from the last 32 days. A variety of analogue and digital interfaces allows smooth system integration and control.

Ozone Meter for ultra pure water

The Ozone meter for gases measures the ozone concentration according to standard DIN 19627 and the IOA (International Ozone Association) at a wavelength of 254nm. According to these standards, the extinction coefficient is 3024 l/mol cm. Therefore, the ozone measurement can be regarded as an absolute measurement requiring no calibration with ozone. The special measuring cell with a path-length of 100mm allows measuring ozone in ultra pure water in the ppb range. For inspecting the instrument, checking units on the basis of reference filters can easily be inserted. Operation is done intuitive using the intelligent control system SICON via touch screen technology and colour display. Values, graphs, alarm and status messages can be presented. An internal data logger allows recalling and displaying measured data from the last 32 days. A variety of analogue and digital interfaces allows smooth system integration and control.
