The document discusses requirements by the Indian Central Pollution Control Board (CPCB) for online water quality monitoring systems to measure various parameters by March 2015. It describes the Micromac ECO system for measuring COD, BOD, pH and TSS along with additional Micromac C analyzers. The systems can transfer data to the CPCB server through a ZetaLOG communication device and provide remote access and data validation through a web-based interface. Calibration is required for accurate site-specific measurements.

2. Indian Central Pollution Control Board direction
•Requirement to on-line measure COD, BOD, pH and TSS in all water outlets of Indian industries, CETPs, hazardous and biomedical waste incinerators
•On-line calibration required
•Collected on-line data have to be sent to CPCB remote server
•On-line water quality monitoring systems have to be in operation by 31 March 2015.

3. Central Pollution Control Board direction (2)
•17 categories of industries were identified
•Other chemical parameters to be added on the basic set of COD, BOD, pH and TSS for the following categories:
Dye and dye intermediate: chromium 6+
Fertilizers: ammonia
Pesticides: chromium 6+ and arsenic
Pharmaceuticals: chromium 6+ and arsenic
Pulp and paper: Adsorbable Organic Halides (AOX).

4. Micromac ECO on-line analyzer:
•Batch sequential multiparametric analysis of COD, BOD, pH and TSS
•To be combined with other Micromac C on-line analyzers tomeasure chemical compounds
•ZetaLOG data acquisition unit to acquire data from Micromac ECO and another Micromac C
•analog acquisition of water flow data can be included.

5. •COD, BOD and TSS are indirectly measured
•Local calibration of COD, BOD, and TSS according to analytical methods are required to provide accurate data for the specific water matrix to be monitored
COD: .by standard dichromate + sulphuric acid colorimetric method
BOD: by 5 days digestion and O2 consumption measurement using DO electrode
TSS: by gravimetric method.
Micromac ECO: local calibrations required

6. Optional on-line self-cleaning filtration unit
•Suggested for any waste water outlet application
•Self-cleaning by compressed air, to be available on-site as standard
•Internal compressed air generator available on request
•Suggested filtration cut-off 100 microns is compatible with TSS measurements.

7. BOD5 direct correlation
with tryptophan
• Tryptophan is an essential amino
acid in human diet and is the
main component of protein
fluorescence.
• It is associated with microbial
activity, i.e. from sewage & faecal
contamination of wastewaters.
• Published data over the past
decade has clearly demonstrated
a strong correlation between
Tryptophan-like fluorescence
and BOD.

8. BOD indirect measurement by fluorimetric method
•Measurement done by the excitation at 280 nm of Tryptophan-like UV fluorescence, measured at 340-360 nm, which correlates with both bacterial loading and BOD
•Internal calibration factor is used to convert the Tryptophan-like fluorescence measured to the reported BOD equivalent value in units of mg/L
•The use of fluorescence provides signal detection sensitivity far superior to optical absorption methods, while the real-time reporting of BOD equivalence enables the measurement to be used for process control
•Featuring autocleaning and programmable calibration check by tryptophan reference solution.

9. BOD
trypthophan like fluorescence method
shows better correlation with BOD5 than
UV (SAC 254 nm) direct reading(*)

11. •Local calibration of COD, BOD, and TSS according to analytical methods are required to provide accurate data
•Built-in autocalibration checks ensure long term measurement stability
•0-5 V or 4-20 mA + digital I/O as standard outputs provide measurement data to the local SCADA
•ZetaLOG integration can provide data to CPCB server and to ZetaCED remote data visualization and validation system, accessible on the Web.

12. Micromac C MP2 Arsenic and Chromium6+ analyzer:
•Power supply: 12 Vdc, 20 W
•Multiparanetric sequential batch analysis
•Low reagents consumption
•Around one hour measurement time (two As sequential strippings)
•Full integration compatibility with Zetalog+ZetaCED

13. Micromac C Arsenic measurement method
•Based on standard Mo- blue spectrophotometric method with preliminary repeated Arsine gas stripping.
•LFA technology ensures reliability and high circuit cleaning
Available ranges from 0-20 ppb

15. Micromac C on-line analyzers: other measurement methods required by CPCB
The automated procedure for the determination of hexavalent chromium in water depends upon the reaction of diphenylcarbazide with hexavalent chromium in an acid medium, to produce a reddish purple colour which can be measured at 520/550 nm.
Chromium6+
Ammonia
In this automated method, the ammonia ions present in the sample react with salicilate in an alkaline medium pH 12, while nitroprusside acts as a catalyst. The blue color is measured at 660-630 nm.

16. Micromac COD
Micromac COD automates the standard bichromate + sulphuric acid method, applied in any laboratory worldwide as COD reference method.
In 2011 the analyzer was successfully tested by Chinese EPA as equivalent method
