Environmental analysis monitoring parameters 

 

CTC can perform a wide range of environmental analyses, such as chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), total organic carbon (COT) and adsorbable organic halogens (AOX). 

Each of these monitoring parameters is able to provide an instant snapshot of the quality of effluent treatment.

COD/BOD analyses 

Chemical oxygen demand (COD) is the quantity of oxygen consumed by the materials present in the water under set operating conditions. 

Biochemical oxygen demand (BOD) assesses the biological oxygen consumption of the sample submitted for testing, to determine the quantity of oxygen that is consumed by microorganisms as they break down the organic components present in the water. 

The BOD5/COD ratio gives an indication of the sample’s potential biodegradability. 

 

Total suspended solids (TSS) 

All effluents contain suspended solids in varying quantities. 

These prevent sunlight from filtering through to the riverbed, which inhibits the development of plants and, consequently, that of aquatic fauna. 

 

Total organic carbon (TOC) measurement 

Total organic carbon (TOC) measurement gives an indication of the presence in water of organic compounds, which may be fixed or volatile, natural or synthetic. 

It can help monitor the evolution of organic pollution in an aqueous environment. 

 

Adsorbable organic halogens (AOX) 

These are organic halogens that are adsorbable on activated carbon. This index represents the quantity of organic compounds containing chlorine, bromine and iodine (but not fluorine).
