Variations of nitrogen transport in the mainstream of the Yellow River, China
Three sections along the mainstream of the Yellow River were chosen as sites for monitoring the concentration variations of nitrogen species. First, the nitrogen in the water was mainly dissolved and dominated by nitrate–nitrogen. Second, the nitrogen concentrations in the middle stream were much higher than those in the upper stream, and close to those in the lower stream. Third, the nitrogen ...

Online Cu, Zn, As, Se, Cd and Sb Monitoring at an Industrial Smelting Wastewater Treatment Plant
This application focuses on measuring inorganic metals including: copper (Cu), zinc (Zn), arsenic (As), selenium (Se), cadmium (Cd), and antimony (Sb), using Cooper Environmental’s Xact® 920, a continuous multi-metal monitor based-on energy dispersive X-ray fluorescence. Industrial facilities consume and discharge various chemicals as a byproduct of the commodity they produce. The ...

Water Management in Smart Cities
Water is at the epicenter of sustainable development and is vital to socio-economic growth, healthy ecosystems, energy and food production, as well as to the very survival of human beings. However, as the world’s population grows to a projected 8.5 billion by 2030, demand for water will increase significantly, intensifying the challenges of sustainable development. The world is becoming ...

Study of physico-chemical quality of the industrial waste water effluent from Gove industrial area of Bhiwandi City of Maharashtra, India
This paper advocates water pollution study of Gove industrial area of Maharashtra, India with special reference to the physico-chemical characteristics of common industrial waste water effluent. The physico-chemical parameters like temperature, pH, solid content, total hardness, chloride content, dissolved oxygen (DO), biological oxygen demand (BOD) and chemical oxygen demand (COD) were studied ...

Act now to beat EU changes to wastewater treatment regulations
Introduction Over the past few months, signals have been emanating from Brussels that hint at tighter wastewater treatment regulations. For instance, not only has Carlos Moedas, EU Commissioner for Research, Science and Innovation, recently been calling for better treatment systems for wastewater, but former Environment Minister, Janez Potočnik, has backed a Friends of the Earth report ...

Research on the process-based risk evaluation method of groundwater pollution for contaminated site
A universal method to evaluate groundwater pollution risk with the site scale has not been established. The groundwater pollution risk is commonly evaluated by overlaying the results of groundwater vulnerability and pollution sources, but this method is inapplicable for contaminated sites. Considering the current supervision demands of groundwater pollution in China, this paper suggests a ...

Main Components of Water Quality Sensors and How They Work
If you're conducting water quality tests, you'll know that the right equipment is crucial to gather accurate data. One such device is a water quality sensor - a tool that detects and measures several water parameters, which can range from temperature to dissolved oxygen to pH levels. Water quality sensors contain multiple components, each integral to their functioning. In this article, we'll ...

Measuring total organic carbon in wastewater
The continuous TOC analysis of industrial waste water is known to be problematic especially, when the TOC analyser is used as a spill monitor for heavily polluted waste water containing a high-load of particles. Thus, most operators require analysers that enable accurate TOC (total organic carbon) measurements. But do they really get those? Common analysers suffer from clogging and blockages due ...

Using UV Fluorescent Technology to monitor for organic pollutants
For many years the water industry has relied on traditional sampling techniques to monitor water quality in a wide range of environments. Traditional tests such as BOD, PH, Dissolved Oxygen and Ammonia have formed the bedrock of monitoring parameters. There are however other ways to establish water quality and UV fluorescence offers an up to date solution for the investigation of Organic ...
