Systea S.p.A.

EASYCHEM COLI online is a microprocessor controlled on-line analyzer automating COLILERT®-18 test to detect coliforms in drinking, surface, waste and bathing water.

EASYCHEM COLI online simultaneously detects both Total Coliforms (TC) and Escherichia coli (EC) or Faecal Coliforms (FC) in water and wastewater. Multiple Tube Fermentation MTF quantitative results are provided within 18 hours, according to the measurement range.

Colilert^®-18 culture medium is the ISO standard 9308-2:2012 and it is also U.S. EPA-approved and included in Standard Methods for Examination of Water and Wastewater.

Designed for industrial and environmental on-line applications, ensures the highest level of robustness in the electronics, mechanics and hydraulics components.

EASY TO INSTALL

The online analyzer is delivered only after a successful final test. It is provided ready for installation, with a spare set for start-up operations.

STATISTICAL EVALUATION OF CONTAMINATION

The online analyzer allows to recognize coliform contamination by performing Presence/Absence (P/A) tests (TC and EC or FC) that can be combined with automated Multiple Tube Fermentation (MTF) quantification at 35-37 °C (TC and EC) or 44.5 °C (FC), with an analytical frequency adjustable to customer’s needs.

At the same time, the Time To Detect (TTD) technique allows early warning estimation of TC and / or FC concentration.

As a result of years of intensive research and development activities, EASYCHEM TOX Early Warning is an original direct reading on-line analyzer based on discrete analysis technology, for fully automated toxicity measurements of water samples using live cultures of luminescent bacteria.

EASYCHEM TOX Early Warning is a on-line automated platform equipped with color touchscreen LCD and housed in an industrial cabinet, comprising a refrigerated compartment, for bacteria, reagents, calibrants and controls. A mechanical arm for aspiration, transferring and dispensing of reagents and samples and a thermostated reaction plate with 80 positions are incorporated with a luminometer, integrated with an automated cuvette washing station.

Easychem TOX Early Warning: acute toxicity automatic measurement with luminescent bacteria

In order to enable an extended time of use of rehydrated cultures by up to ten days, proprietary bioluminescent bacteria were selected, grown, stabilized and lyophilized according to standard methods. Thus, for the required period, the microorganisms preserve a measurable bioluminescence signal and an unaltered sensitivity to different types of reference compounds defined in ISO and GB-T standards, such as zinc sulphate and mercury Chloride. The system is programmed to manage several bacterial vials in succession, thus enabling an high frequency measurement for one month or up to three months of unattended operation with lower measurement frequency.

Fully automated for unattended toxicity monitoring

Timing and frequency of analytical cycles, limits and parameters of quality controls are programmable by the operator and managed automatically. The continuous measurement of blanks and samples at pre-defined time intervals of about 40 seconds, results in the generation of inhibition kinetics, which allow to achieve, from the very beginning of the analysis, preliminary information on the level of sample contamination.  Following a toxicity alert, the system is able to react immediately by automatically replicating samples and performing control checks to confirm identified toxicity, significantly reducing the occurrence of false positives. 

EASYCHEM TOX Early Warning provides local data storage via seriale RS-232 with separate optional analog outputs 4-20 mA, remote data storage on a web server and data transmission via ftp, http and SMS. An immediate alert service is available in case of detected noncompliances. Finally, the management software allows the integration of different instrumentation, thus realizing a truly integrated monitoring station, combining chemical and toxicological on-line control of water samples.

A mechanical arm for aspiration, transferring and dispensing of reagents and samples and a thermostated reaction plate with 80 positions are incorporated with a multi-wavelength spectrophotometer, integrated with an automated cuvette washing station.

Multiparametric on-line analysis for chemical parameters

The on-line analyzer can be configured to automatically measure up to 10 chemical parameters, using standard methods and including complex procedures such as the determination of total phosphorus and/or total cyanides, which are performed by means of multichannel external pretreatment modules, complete with a filtration system.

Several data interface available as standard

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.
