Micromac ECO

On-line analyzer for COD/BOD/pH/TSS or COD/Color/pH/TSS

MICROMAC ECO is a microprocessor controlled on-line analyzer, specifically designed for automatic monitoring at the outlet of WWTPs.

  • Robust and Reliable
    Designed for industrial and environmental on-line applications, it ensures the highest level of robustness in the electronics, mechanics and hydraulics components. With a complete separation between electronics and hydraulics and a simple and robust hydraulics allows long term and reliable operations.
  • Easy to install
    The analyzer is delivered from factory only after a successful final test. It is provided ready for installation, with a spares set for start-up operations.
  • Automatic calibration
    The analyzer performs automatic calibration, the new calibration factor is checked and accepted if inside acceptance limits.
  • Measuring interval
    User selectable; between two measurements the analyzer remain in stand by mode, without reagents consumption.
  • Off scale reanalyze
    The analyzer identify off scale samples, and starts the analysis in dilution mode automatically.

On-line filtration

Self-Cleaning Filtration Unit

For waste water or other dirty samples application a self-cleaning filtration unit can be installed close to the analyzer. Thanks to the integrated PLC, the filtration unit runs periodically a self cleaning cycle, using compressed air generated externally or even internally (as option). One filtration unit can be used to supply a clean water sample up to 10 analyzers.

Easy to install 
The filtration unit is delivered completely assembled on a stainless steel and PVC frame, ready for connection to a sample line. It is sufficient to connect the main sample line, the waste line and the analyzer’s filtered sample line.
 
Low maintenance 
  • Self cleaning cycle and long life pump tube ensures low maintenance cost.
  • Analyzer controlled: Micromac activates the filtration unit only when the analytical cycle starts.
  • Stainless steel filter ensures long operation and no corrosion with the most common matrix.

Micromac COD

On-line analyzers for COD monitoring
in water and wastewater

 

Three versions of COD on-line analyzers are available:

  • dichromate method
  • permanganate index method
  • UV direct reading method.

The dichromate method follows the international standard where in the sample, after filtration, Potassium Dichromate, Mercury (II) sulfate and Sulfuric acid with a proper catalyst are added; Mercury (II) sulfate concentration is adjusted to mask the expected Chloride amount.

The sample is then heated at 170° for 20 minutes or at 150° up to 2 hours (digestion time and digestion temperature can be adjusted depending on the matrix to digest completely all the substances that give a contribute to COD). After digestion the sample is cooled and the absorbance measured at 592 nm is proportional to a COD concentration.

The permanganate index is defined as the quantity of oxygen, expressed as mg/l, equivalent to the consumed permanganate when a water sample is treated with as solution of potassium permanganate in acid environment and at a temperature of 100°C for 10 minutes. The sample is mixed with diluted sulphuric acid, it is then heated at about 100°C, when the first addition of KMnO4 is performed: this first addition may be followed by others, depending on the measuring range. The digestion time in the standard configuration is set to 10 minutes but it can be selected depending on the matrix.

After digestion the sample is cooled and the decrease of the absorbance measured at 525 nm corresponds to the permanganate consumed by the organic substance.

The UV direct reading method is a more simple method where the COD is correlated to the direct light absorption of the water sample measured at 254 nm.

Micromac C

On line analyzer for potable, surface and waste water monitoring

MICROMAC C is a colorimetric microprocessor controlled On Line analyzer specifically designed for automatic monitoring on several type of waters matrix.

  • Robust and Reliable: designed for industrial and Environmental On Line applications ensures the highest level of robustness in the electronics, mechanics and hydraulics components. Complete separation between electronics and hydraulics plus a simple and robust LFA* hydraulics allows long and reliable operations.
  • Easy to install: the analyzer is delivered only after a long and successful series of final tests. It is ready for installation, without any further adjustment, and is complete of a spares set for start up. To start monitoring is enough to connect sample line, waste line and power supply.
  • Automatic Calibration: upon a user selectable Calibration Time expiring the analyzer perform a Calibration Cycle, storing and checking the new calibrant O. D. If new O.D. exceed selected limits, an alarm contacts is closed.
  • Sample dilution: each sample can be analyzed as it is or in dilution mode. Dilution mode can be activated also on off scale samples with a dilution factor, factory selected, up to 100.
  • Measuring interval: user selectable; between two measurements the analyzer remain in stand by mode, without reagents consumption.
  • Off scale reanalyze: The analyzer identify off scale samples, and starts the analysis in dilution mode automatically.

Features and benefits

  • Fully automatic operation;
  • Long autonomy; low maintenance, low operating cost;
  • Low reagents consumption; short preparation time; low disposable costs;
  • Easy operation; fully documented plug in analyzer, no special training is required;
  • Electronics and hydraulics completely separated;
  • Serial interface for PC or printer connection (optional).
