Multiple device configurationsUp to three light sources can be installed in the instrument. This allows simultane-ous measurement of DOC (UV absorpti-on) and colour (Hazen) and compensation of turbidity: Two measurements are available in

one instrument. The real colour is measured. DOC (UV absorption) is measured

without the influence of turbidity.

Flow cell and cover with screwsThe cover of the flow cell can be opened without tools: Allows simple access for cleaning the

flow cell. Cleaning involves little effort.

Compensation glassSoiling of the flow cell is measured by me-ans 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.

Checking unitFor inspecting the instrument, checking units on the basis of reference filters can easily be inserted: A checking unit is included in the basic

configuration and allows the checking of high absorption. Further checking units are available

for checking various measuring points.

Intelligent Control SystemThe SICON control unit with state-of-the-art 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.

ColorPlus 2 SystemMonitoring of the elimination of micropollutants (4th treatment stage)

Complete system for measuring UV absorban-ce (254nm) with automatic cleaning at 2 to 4 measuring points

Measurement of absorbance before and after ozonation with the Sigrist ColorPlus 2 to determine the absorban-ce difference. With expansion modules, the ColorPlus 2 system can be extended to up to 4 measuring points. The time-controlled, automatic cleaning with cleaning liquid and subsequent blowing out with compressed air constantly enables very precise measured values. The basic version of the ColorPlus 2 system consists of:

• 2 absorption measuring instruments ColorPlus 2 Bypass

• System for automatic cleaning of the flow cell with compressed air and detergents

Advantages of the SIGRIST complete system

Customer benefits

• The elimination of micropollutants is precisely measured before and after ozonation.

• Controlling the ozone plant to achieve a low energy consumption low.

• Automatic cleaning of the flow cells prolongs the cleaning intervals. - Maintenance is considerably reduced.

- The whole plant can be operated for a longer period without the need to stop the plant.

The elimination of these trace materials in waste water can be achie-ved by two processes:

• The use of ozone to oxidize the substances.

• Use of Powder Activated Carbon PAC to adsorb and subsequently filter those substances. Together with the PAC, these substances can then be filtered out.

There are advantages and disadvantages to both methods. The common feature is that only as little as possible and as much as necessary ozone or PAC should be used. Thanks to the permanent monitoring of the absorbance difference, the optimum dosage can always be ensured.

Pict. 1 List of micropollutants in waste water of the waste water treatment plant

ARA Dübendorf (Source: eawag)

Based on the experiences and examinations made in previous years, a practical test using ozone in a pilot plant was carried out at the eawag in Dübendorf in 2011/2012. This demonstrated the elimination of trace substances by ozone. At the same time, control of the process was determined which guarantees optimal ozonation. Only relia-ble control makes it possible to keep the energy consumption required for this process low. Thus, the idea of „measuring the absorbance difference by ozonation with photometers“ was established.

Pharmaceuticals, detergents, pesticides, cosmetics, shower lotions and many other substances can only be partially or not at all biologically degraded in watertreatment plants. These micropollutants (also called trace substances) can only slightly sorbed to the sewage sludge, which is why the retention of these trace substances is insufficient.
