Custom-fitted TOC process analyzer

The total organic carbon process analyzer is a measuring system for complex water applications for monitoring and optimization of industrial processes and municipal as well as industrial waste water treatment plants.

LAR's TOC process analyzer QuickTOCultra is a measuring system for complex water applications. Due to a patented injection and oxidation technique, the analyzer easily handles sticky, fatty, salty, and high-particle samples. The sample is injected via a robot-driven injection system to the furnace, whereby pre-treatment or dilution is unnecessary. In the furnace, the sample is combusted at 1,200°C. Based on the high temperature, the organic content is completely oxidized to CO2. Hence, operators do not need expensive oxidation promoting catalysts. Besides, the QuickTOCultra convinces with a fast response time of less than three minutes as well as with a high availability of up to 98%. The TOC analyzer is operated by touch-screen display. The TOC analyzer can be adapted to the requirements of the different applications by means of modules such as the measurement of 6 sample streams in one analyzer.

The custom-fitted analyzers are optimally suitable for monitoring and optimization of industrial processes and municipal as well as industrial waste water treatment plants.

The total organic carbon (TOC) is one of the most important sum parameters in the assessment of the organic pollution of water. Since it includes all carbon compounds as one mass, it is exactly defined and an absolute quantity. Therefore, it may be determined directly.

The chemical oxygen demand (COD) indicates the amount of oxygen which is needed for the oxidation of all organic substances in water and is thus an important indicator for water analysis. It is considered in the planning and controlling of treatment, as well as assessing its efficiency, thus forming the basis for the calculation of waste water charges.

The COD can be determined in laboratory or online, whereby these methods significantly differ in duration and consumables used.

The biochemical oxygen demand (BOD) indicates the amount of oxygen which is needed for the biological degradation of organic substances in water.

Since the generally used BOD5 excludes the nitrification part of the process, this parameter is poorly suited for the control of waste water treatment plants. Alternatively, the total BOD is well-suited, due to the determination of the nitrogen as well as the carbonaceous part of biological degradation.

Toxicity is described as the direct harmful effect of a substance on organisms. These effects can already occur at low concentraions of toxic substances and are dependent on the incubation period and the dosage.

Some test methods that are available on the market can detect toxicity by using fish, daphnia, molluscs, algae or luminous bacteria and testing whether a water sample has a toxic effect on the organisms. They do not, however, identify exactly which toxins are present.

The total nitrogen bound (TNb) shows the pollution of water caused by nitrogen compounds. Nitrogen may be present as ammonia, ammonium salts, nitrites, nitrates and organic nitrogen compounds.

In contrast to single measurements of the above-mentioned components, the TNb determination contains all these substances in a single analysis process.

The total phosphorus (TP) is a sum parameter that shows the organic and inorganic phosphorus compounds in water. Phosphorus is an essential nutrient for humans as well as flora and fauna. However, the substance – depending on its concentration– may cause serious damage.
