COD Analyzer for Low Particle Density Water
The Elox100 of the LAR Process Analysers AG is an online COD analyzer for the determination of chemical oxygen demand (COD) in waste water treatment plants or in the process industry.
LAR's chemical oxygen demand analyzer is suitable for a variety of applications and types of water:
Using analyzer options, the measurement system is adaptable for every measurement challenge.
For safe operation in hazardous areas, there are different protection housings available:
With the patented Lead-Dioxide-Electrode by LAR OH-radicals are produced. Compared to other oxidants OH-radicals have a significantly higher oxidation potential. Thus, hard to oxidize substances can be fast and easily oxidized without using dangerous chemicals.This electrochemical principle is used for our Elox100. During the reaction the electricity produced will be measured, which is proportional to the consumed OH-radicals. The OH-radicals are here again directly related to the COD.
This method offers a fast, simple, accurate and pollution-free alternative to the common dichromate method (wet chemical method).
The measurement of the COD takes place in less than 4 minutes and therefore it is faster than the convential dichromate method, which requires 2 hours. This speed guarantees that very short peaks can be determined very well during a daily cycle.
The analyser's availability is over 98%. The weekly service of the COD analyser is about 30 minutes.
