Online COD BOD TOC Analyser with Wiper ISO Manufacturer

COD and BOD can be indicated as mg/L or ppm (parts per million).
Both parameters measure the amount of oxygen needed to oxidize pollutants in water.
Also, both measurements indicate the intensity of water pollution.
Almost all wastewater treatment plants are required to measure one of these three items as a measure of the pollution value in the water. COD should always measure higher than TOC and then BOD.
Quantity:
  • PUVCOD-900
  • PROBEST

Measurement Principle

Based on the UV absorption reaction by organic matter, the PUVCOD-900

Spectromete Organic On-Line Analyzer uses the 254 nm spectral absorption

coefficient SAC254 to measure the content of soluble organic compound in the water,

and it can be converted to COD or BOD values under certain conditions. This

method allows continuous monitoring without any reagents.


Features

Direct-immersion probe measurement without taking sampling and pretreatment.

No chemical reagents, no secondary pollution.

Short response time for continuous measurement.

The sensor has an automatic cleaning function to reduce maintenance time.


Application

Continuous monitoring of organic load during sewage treatment, online real-time monitoring of influent and effluent water quality of wastewater treatment plants.

Continuous on-line monitoring of surface water, industrial effluent, and fishery wastewater.
