Standardized protocols require the inclusion of a positive control with a known BMP to check the experimental setup and execution, as well as the performance of the inoculum. Find out how to validate the results of your analysis with a control test of the instrumentation and of the procedures you adopt.

Biochemical Methane Potential is an anaerobic analysis that consist in small scale reproduction under optimal conditions of the anaerobic digestion of the complex organic molecule in order to have simpler molecules, with the final production of biogas. Find out how to determine the BMP of sludges from the municipal sewage plant.
 

生化需氧量(BOD)是测定水中需氧生物微生物消耗溶解氧量的分析方法。为了检查完整的BOD EVO传感器系统，可以使用Control Test Tablets(code)，进行类似BOD方法的需氧量实验。

Sewage sludge generated from wastewater treatment plants are being merited greater attention in light of their potential for improving soil properties and for providing important nutrient and trace element supplements that are essential for plant growth. TOC determination is important because high levels in soils prevent the anaerobic digestion process and limit the subsoils nitrogen enrichment.

The analysis involves the use of aerobic microorganisms in an aqueous medium containing inorganic salts and the organic material to be tested (the only carbon source) with a concentration of organic carbon between 100 and 2000 mg/l. The mixture is stirred in a closed vessel.

The determination of phenols is one of the routine analysis in order to assess the quality in drinking and ground water and in domestic and industrial wastes, even at low concentration. Learn how to obtain excellent performance with UDK Series and how to work in accordance with CNR and ISO.

水是地球上最重要的资源，对人类和其他生物一样。尽管如此，世界上仍有近一半的人口无法获得可接受标准的饮用水。地下水通常是一个良好的饮用水来源，因为水是自然净化，当它缓慢地渗透到土壤。

水、废水和污泥的性质因其来源而有很大的不同。例如，在未受污染的水域中，低氮水平使得有必要使用大样本容量。了解如何通过DK / DKL和UDK系列获得优异的氮素分析性能，以及如何按照AOAC, EPA和ISO方法标准进行分析。

Learn about BOD analysis on samples of wastewater with the VELP RESPIROMETRIC Sensor, associated with the Wireless DataBox™ and the RESPIROSoft™ dedicated software. The VELP solution maximizes the reliability of measurement and enables the observation of the analysis in real-time, as it progresses.

Learn how disinfectants have an influence on the biodegradability of organic matter in terms of BOD. A study supported by VELP Respirometric System.
