Nitrogen and phosphorus are essential elements for humans as well as flora and fauna. In addition to their role as a nutrient their presence can also give important information about a sample e.g. the practice of over-fertilization or the likelihood of heavy metals being present in water bound to phosphate. Consequently, the determination of these elements is indispensable for the evaluation of water quality. The analysis of Total Nitrogen (TN) and Total Phosphorus (TP) to estimate such ri...

Presented at WWEM 2018. Nowadays, the tight environmental regulations demand a close control of the water quality in rivers, sea or even in waste waters. The water quality control require a regular monitoring due to continuous changes in several key parameters, such as seasonal water chemistry, overgrowing of plants, industrial waste and other factors. The chemical, physical and biological properties of the water define its quality. Currently, monitoring analytical parameters like the pH, te...

A fast and reliable characterisation of biodegradable organic matter (BOM) is essential to ensure efficient pollution removal by wastewater treatment plants (WWTP) along with a necessary reduction of the environmental footprint resulting from treatment process operation (energy and raw material consumption, greenhouse gas emission). Biochemical Oxygen Demand (BOD) is a worldwide used indicator for assessing the BOM content of wastewater. The BOD measurement rests on a 100 years old analytical...

Whatever your requirement is with regards to monitoring your water data it is undoubtedly true to say the quicker that you receive the data back the more efficient and effective you can be at responding to it in the right location. With potentially vast pipework networks in place its often the case that you can only react when there is already an issue, not proactively to prevent potentially unacceptable levels of change. The movement of the 'Internet of Things' seeks to change this by mon...

Engineered silver nanomaterials (AgNM) have become an essential part of our daily life. Being used as antibacterial mean in numerous products such as e.g., deodorants, cleaners or sportswear, AgNM finally end up in the environment, where their behavior and fate is still widely unexplored mainly due to the lack of available analytical techniques and methodologies for their determination at trace levels in complex matrices. In this presentation, the hyphenation of Asymmetrical Flow Field-Flo...

Traditionally, water chemistry has been measured by taking spot samples, either manually or using autosamplers, transporting to a laboratory where the samples are then analysed. In situ analysis removes the logistical problem of transporting samples, meaning larger data sets can be obtained. The quality of data can be higher by removing the risk of sample deterioration or contamination. Furthermore, it raises the possibility of large scale networks of sensors deployed on moorings and auton...
