Chemical Oxygen Demand
It is vital that industrial effluents comply with regulatory consents imposed by local water autorities/environment agents. Discharge maximums are often set for COD and TOC as these general measurements of discharge water quality. Other consent levels can be set for the process of specific items such as chromium, phosphate and nitrogen Heavy fines are possible for continued breaches of consent values. The Lovibond ® COD system is simple to operate, requires no training and enables industry to rapidly assess effluent quality and remain fully compliant.
The Lovibond® Chemical Oxygen Demand system is made up of 3 components; the MD100 COD photometer, the RD125 thermoreactor and COD Vario tube tests.
MD100 COD Photometer
COD VARIO Tube Tests
The Lovibond® COD VARIO tube tests use a sealed tube system based upon the standard dichromate method and can be consindered as an estimate of the theoretical oxygen demand, i.e the amount of oxygen consumed in total chemical oxidation of the organic constituents present in the water.
