Dissolved Oxygen sensor oxi::lyser DOCall for price
No Consumables Dissolved Oxygen Probe Overview
The main application of the oxi::lyser is the online control of the most cost-intensive wastewater treatment process, namely the aeration of the biological carbon and nitrogen removal. The activated sludge increases its activity with rising oxygen concentrations, but this increase is not linear: Above approximately 2.5 mg/L a further elevation in oxygen does not increase the nitrification enough to justify the rise in costs of aeration. Furthermore, too high oxygen concentrations interfere with the process of denitrification. Therefore the oxygen concentration should be controlled online in the entire biological nitrogen removal process. Using the nitro::lyser™ and the ammo::lyser™ to monitor the nitrogen continuously in combination with the oxygen the operational procedures, as well as the economics of wastewater treatment, can be optimized.
In drinking water applications the Dissolved Oxygen is mainly used in early warning systems detecting problems in raw water quality: Reduced dissolved oxygen concentrations are often an indicator for harmful microbial or chemical contaminations of the water. Applied in natural waters or on fish farms the oxi::lyser™ can detect anaerobic conditions, which are life-threatening aquatic organisms, and thus it helps to prevent ecological as well as economic damage.
This Dissolved Oxygen probe measures the concentration of dissolved oxygen and the temperature directly in the water. The oxi::lyser™ does not need a minimum flow to produce accurate readings and uses the temperature measurement for On-Line correction. The sensing element, which uses the principle of fluorescence for the oxygen measurement, is neither affected nor damaged by direct exposure to sunlight. Under normal conditions, the fouling of the sensing element will not affect the results. However, to be sure that fouling is kept to a minimum, the oxi::lyser™ can be cleaned automatically with compressed air. The oxi::lyser uses no replaceable parts or consumables. Therefore, when operated properly there will be no costs for spare parts at all. For the oxi::lyser™ we guarantee replacement of spare parts free of charge for the first three years after delivery (upon presenting the warranty card).
