On-line water quality analysis with real time data transfer Ing. Luca Sanfilippo Project Manager Marketing Manager
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.
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 ) .
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.
Micromac ECO: local calibrations required 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 O 2 consumption measurement using DO electrode TSS: by gravimetric method.
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.
BOD 5 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.
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.
BOD trypthophan like fluorescence method shows better correlation with BOD 5 than UV (SAC 254 nm) direct reading (*) (*) Using Synchronous Fluorescence Technique as a Water Quality Monitoring Tool for an Urban River, Jin Hur & Soon-Jin Hwang & Jae-Ki Shin Water Air Soil Pollut (2008) 191:231 – 243

Micromac ECO: operativity and data output 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.
Micromac C MP2 Arsenic and Chromium 6+ 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
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
Micromac C Arsenic (low level) test:
Micromac C on-line analyzers: other measurement methods required by CPCB Chromium 6+ 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. 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.
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
