To estimate the quality of water by measuring the TOC / BOD / COD in effluent at ETPs, industries etc.
Online monitoring  of  effluents  is  mandatory  for specific category of industries in India.

However  choosing  right  technology  is important, as monitoring is not  a short term job.

The equipment need to be  rugged, reliable (result comparable to lab data),  economical, well supported by manufacturer and local distributor with  inventory of spares and skilled manpower. The system shouldn't require recurring cost in reinvestment for replacements at a later stage. Also, the instrument need to comply Local and International Standards.

We at SWAN Environmental Pvt. Ltd., consider all the above points to be best choice for our customers.

We supply  Water Quality Monitoring Systems , integrated  with multi channel analyzers which  accepts  sensors  like  Ph, TSS, Flow, & TOC analyzer  which  directly measures COD / BOD / TOC and Flow based on ultrasonic or magnetic (users choice) flow meters with  all options connected to SDL-999V - Data Acquisition System or PC-DL-999V - PC based Data Logging System.

The Online BOD / COD analyzer based on  Online TOC analyzer  works on established CPCB recommended 680deg C catalytic combustion and non dispersive infrared detection (NDIR) method based on USEPA/ ASTM methods. The data shows accuracy near to Lab analysis. This is important  in  case of later verification by regulatory authorities and comply to actual data.

Single stream and multi stream capabilities:

The BOD/COD analyzers  can take multistream inputs from different sources. More than one ETPs can use one Analyzer with this capability , reducing the cost of the investment drastically. However , the strategical suitability  need  to  be  confirmed by us, looking at sampling distances.

Also, with two inputs, once can establish the efficiency of ETPs, by comparing data from influent and effluent.

Our  single  configuration  for  BOD , COD , TSS , Ph , Flow including  Data  uploading includes:
a) Online TOC Analyzer
b) TSS sensor with analyzer
c) PH sensor with Analyzer
d) Flow meter
e) Data Acquisition system with software* [*PC need to procured by customer at site]
f)  Data uploading software from DAS/Client PC to SPCB and CPCB
