  • NoiseNews: Something Fishy Going on in British Waters?

    The seas around Britain may be getting too noisy. So noisy in fact that fish species such as cod and haddock are having difficulty communicating with each other. If their chatter is being obscured, it could affect their ability to breed at a time when stock numbers are recovering. It has long been recognised that large marine mammals are susceptible to noise pollution – as ...

  • Techniques for Soot in Oil Analysis

    Since no engine is 100% efficient, products other than carbon dioxide and water will be formed during combustion. One such product produced from incomplete combustion is soot. Soot is a mass of mainly carbon particles that are typically spherical in shape. As soot levels rise, the soot particles begin to clump together and ...

  • Techniques for Oil in Water Analysis

    The people responsible for conducting oil in water measurements understand that the measurement can be quite challenging. Wastewater from different sources can contain many different types of hydrocarbons, each with different chemical make-ups. On top of the lack of chemical uniformity in different oils, there has been a ...

  • What’s a Luminometer? And Why Should You Care?

    If you’re in the business of managing a water system – whether drinking water, wastewater or water used for industrial purposes – a luminometer can make your job easier. Luminometers have been used in labs for decades, helping to provide easily interpreted answers to molecular questions. The ...

  • Produced Water Case Study

    Challenge Managing the increasing volumes of produced water associated with oil & gas production as well as sourcing water for operations is becoming more challenging for E&P companies. Handling oily wastewaters with high and variable contents of O&G and TSS requires complex and costly treatment trains with conventional technologies. To evaluate akvoFloat ’s ...

  • Relations between abundance of potential geosmin- and 2-MIB-producing organisms and concentrations of these compounds in water from three Australian reservoirs

    Relationships between the abundance of potential geosmin- and 2-methylisoborneol-producing (2-MIB) cyanobacteria and bacteria, and concentrations of the two taste and odour compounds (T&Os) were examined in a 7 day incubation of natural water from the surface and bottom of three reservoirs in southeast Queensland, Australia. Only a single known T&O-producing cyanobacterium ...

  • New indices for reliability assessment of water distribution networks

    This paper presents new indices to evaluate the reliability of water distribution networks (WDNs) usable in the design, planning and management of these networks. Since the pressure-driven analysis (PDA) of WDNs produces more accurate results than the demand-driven analysis, the new indices are proposed based on the PDA. In the proposed measures, nodal pressures, nodal available discharges and ...

  • Case study - Crude oil in water

    Produced Water Treatment Site: A pilot study was performed to test water samples contaminated with produced water from several oil well production sites in Wyoming for a company that provides mobile water treatment systems that enable oil and gas companies to recycle and reuse flow back water more efficiently. The samples were tested for their gasoline range and extended diesel/oil range ...

  • Biosurfactant produced by a Rhodococcus erythropolis mutant as an oil spill response agent

    Biosurfactants have been considered as superior alternatives to currently used surfactants as they are generally more biodegradable, less toxic, and better at enhancing biodegradation. However, the application of biosurfactants is limited by the availability of economic biosurfactants and the corresponding producers that can work effectively. Hyperproducers generated by metabolic engineering ...

  • Multivariate statistical analysis for water demand modelling: implementation, performance analysis, and comparison with the PRP model

    Water demand is the driving force behind hydraulic dynamics in water distribution systems. Consequently, it is crucial to accurately estimate the actual water use to develop reliable simulation models. In this study, copula-based multivariate analysis was proposed and used for demand prediction for a given return period. The analysis was applied to water consumption data collected in the water ...

  • Determinants of water purchases by pistachio producers in an informal groundwater market: a case study from Iran

    Market-based water allocation systems have the potential to ensure that scarce water will flow to the user who earns the highest marginal value from that water. However, the number of recorded instances where water supply problems are solved by market-based systems remains limited. This study attempts to identify the decisive factors that motivate farmers’ participation in informal spot water ...

  • Energy analysis of reclaimed water application for irrigation in arid and semi-arid regions

    Freshwater availability is the major constraint to agriculture in arid and semi-arid regions. The groundwater and energy conservation of applying reclaimed water for irrigation was analysed, using Southern California as the spatial domain for model testing. An extensive compilation of the most recent publicly available datasets was used to calculate the energy intensity for each water supply ...

  • Two phase partitioning bioreactor applied to produced water treatment

    Produced waters are the largest waste associated with the production of oil and gas; they contain dissolved salts, oil (dissolved and scattered organic compounds), chemicals and additives involved in the oil well operations, suspended particles, sand and other compounds, making their treatment very complex. In this paper, we propose the use of a TPPB (two phase partitioning bioreactor) for the ...

  • The dynamics of the European water research network: a diversifying community with a stable core

    Both in water management and in research policy there is a call for more integrative approaches to tackle large societal challenges. This requires collaboration in networks of actors with different institutional and geographical backgrounds. However, our understanding of the European water research network is limited. Applying social network analysis to data from projects in Framework ...

  • Analysis of sludge aggregates produced during electrocoagulation of model wastewater

    This paper presents the results of the study of sludge aggregates produced during electrocoagulation of model wastewater of a composition corresponding to the effluents from the cellulose and paper industry. Wastewater was electrocoagulated statically using aluminium electrodes with a current density of 31.25 A m−2 and 62.50 A m−2. In subsequent stages of the treatment, sludge flocs were ...

  • The Water Conditions in Ethiopia, Part One

    In August, I was able to visit northern Ethiopia to look at some of the drinking water issues. As you might guess, there are many, ranging from polluted water to almost no water at all. That made it interesting to discover the inhabitants of Adwa and Aksum rely on a reservoir. The reservoir water is treated first by aeration to oxidize iron, then with a flocculant which attracts dirt like a ...

  • Comparative analysis on the effectiveness of various filtration methods on the potability of water

    This paper comparatively assessed the effectiveness of potable water filtration methods, commonly used in the hinterlands in some Ghanaian communities. Physico-chemical and microbiological analysis were carried out on pond, dam and river water samples, using spectrophotometric, pour plate count and the most probable number (MPN) methods. For the unfiltered water samples the total dissolved ...

  • Comparative Testing of Corexit EC9500A, Finasol OSR52, Accell Clean DWD, and ZI 400 at Ohmsett in a Simulated Arctic Environment

    The Bureau of Safety and Environmental Enforcement (BSEE) recently conducted independent dispersant effectiveness testing. Several products were tested under simulated arctic conditions at Ohmsett. The test program was conducted to better understand the effectiveness of various dispersants under the test conditions and compare the products. The results will assist BSEE and its federal partners in ...
