Modelling a complicated hydrogeological system: The case study of Wadi Zerka Ma'in - north east of Dead Sea Taleb Odeh1 Tino Rödiger2 1 Arid land academy, The Hashemite University, P.O. Box 330127, Zarqa 13133, Jordan 2 Catchment Hydrology Department, Helmholtz Centre for Environmental Research-UFZ, Theodor-Lieser-Strasse 4, 06120 Halle, Germany Abstract Wadi Zerka Ma'in catchment area is a complicated study area from geomorphologically, hydrologically and hydrogeologically point of view. Th...

The 'Cloud' has the promise of tools and services to deliver and promote an effective and efficient operation. This paper will show tangible benefits of Cloud Based Technologies in wastewater pumping monitoring and control. The benefits are shown in a life cycle cost perspective comparing cloud based solutions with traditional monitoring and control installations. Results are based on experience from more than 2500 connected pump stations and other water assets globally.

The benefits of decision support systems for environmental management are often challenging to value, particularly where they include intangible benefits that require a detailed understanding of operating procedures, such as risk mitigation or operational improvements. This paper describes the methodology used to value a cloud-based decision support system for odour risk management implemented at two wastewater treatment plants in England in mid-2016. The system was used for rapid analysis an...

Technical improvements of the leading odour removal concept by implementation of secured network technology for dosage control systems.

Burning coal and other fossil fuels is widely used for generating electricity or thermal heat, but because of the combustion process, particulate matter and nitrogen oxides (NOx) are released into the atmosphere. NOx and dust are the leading cause of human respiratory issues and government agencies worldwide are releasing stronger regulatory measures designed to reduce air pollution. In countries like the United States, offer NOx trading credits for excess reduction, making it more valuabl...

Aguas de Alicante has developed an online Big Data Solution in Alicante (Spain) to determine water demand in short (6 days) and medium time (12 months). This is an example how a Smart City could use data to improve the sustainability of the city.

NOW ONDEMAND Inorganic anions and cations are major components of drinking water, and are responsible for its unique taste and hardness.  However, some components, such as nitrite, bromide, strontium, manganese, and others represent risks to human health when consumed in excess of prescribed amounts. Other components, such as sodium and potassium should be consumed with caution among those at risk for heart disease or allergic reaction. Even fluoride, necessary for healthy teeth, becomes...

NOW ONDEMAND In this webinar, Lumex Instruments experts George Debus and Nikolai Ivanov discuss the advantages of atomic absorption spectroscopy with Zeeman background correction (ZAAS) for the analysis of mercury in complex samples. Determination of mercury in complex samples is always a challenge for the laboratory analysis. This especially applies to soil, crude oil, wastewater, ores, foodstuff, and  biological samples. As a rule, these objects are a complex mixture of various organ...

ABSTRACT: Sewage contains the excreted biomarkers of endogenous human metabolism that directly reflects the exposure and stressors placed upon an entire contributing community. The quantitative measurement of these specific biomarkers in sewage from communities allows the averaged patterns of factors related to lifestyle, disease and environment to be used for the assessment of human health and the environment. While most research in this field has been aimed at estimating the use of il...

ABSTRACT: Total Organic Carbon (TOC) is a measure of the carbon content of dissolved and undissolved organic matter present in a water sample. TOC analysis has been a dependable method used for waste minimization, product loss prevention, industrial and municipal waste water treatment plant control, final effluent discharge monitoring, process-cooling-boiler-condensate-intake-surface water monitoring, and many other water monitoring purposes in the industry. TOC measurement has a direct re...
