  • Tipping Back an “Interesting” Pint

    How about a nice tall glass of ice-cold beer… made from recycled sewage water? Did you hesitate? Well, now let’s think about it: most breweries use some combination of hops, malted barley, yeast, and…. well… clean water! But beer from recycled wastewater? That’s exactly what took place March 19-10 at the 2017 WateReuse California Annual Conference in San Diego. ...

  • Times are changing: Wastewater as a resource

    Times are definitely changing. It used to be that wastewater from whatever source – domestic, agricultural, industrial – was something to collect and pipe away as quickly and efficiently as possible. There was more water coming out of the ground or falling from the sky, so why bother investing time and money cleaning water that had already been used? Now, thanks to issues like ...

  • Industrial Wastewater

    Industrial wastewater treatment covers the mechanisms and processes used for water treatment where has been contaminated in some way by industrial or commercial activities before wastewater is released into the environment or reused. Recent trend in the developed world is to minimize the production of wet waste like water or something else and to recycle such waste during the production process. ...

  • How new technologies are shrinking wastewater’s hefty carbon footprint

    Wastewater treatment plants are energy hogs. A 2013 study by the Electric Power Research Institute and Water Research Foundation reported that they consumed about 30 billion kilowatt-hours of electricity per year, or about 0.8 percent of the total electricity used in the United States. Wastewater treatment’s high energy footprint is ironic because the organic matter in wastewater contains ...

  • Understanding the 3 Types of Arsenic Removal Used for Wastewater

    With the onset of the Industrial Revolution and the development of internal combustion engines and new manufacturing technologies, fresh water became an essential raw material not only for production, but for cooling purposes in manufacturing processes. However, when fresh water is used in an industrial process, it creates industrial wastewater composed of a variety of chemicals and other raw ...

  • World Water Day 2017 - Wastewater

    On Wednesday 22nd March, Aquaread will be joining many other charities, organisations, businesses and individuals in celebrating World Water Day – an annual event raising awareness and support for water conditions throughout the world, with the aim of tackling the water ...

  • Electrochemically-assisted ammonia recovery from wastewater using a floating electrode

    This work presents and explores a novel methodology for the removal and recovery of ammonia from wastewater based upon two mechanisms: electrochemical oxidation and a previously unreported electrochemically-assisted surface transfer mechanism. Recovery of ammonia is enabled by placing a porous cathodic electrode at the wastewater-air interface. In this configuration, the cathode creates local ...

  • Investigating the interactions of decentralized and centralized wastewater heat recovery systems

    In the urban water cycle there are different sources for extracting energy. In addition to potential and chemical energy in the wastewater, thermal energy can also be recovered. Heat can be recovered from the wastewater with heat exchangers that are located decentralized and/or centralized at several locations throughout the system. It can be recovered directly at the source (e.g. in the ...

  • Plastic Recycling Industry - Case Study

    Introduction Bottle Recycling has been on the uprise for a number of decades. As the global community becomes more aware of the practices and benefits of reuse and recycling of plastics, they are also demanding that better controls be put in place by the manufacturers, corporations, environmental agencies and end users. This promotes these groups to look toward new technologies that are ...

  • Diagnosis and optimization of WWTPs using the PWM library: full-scale experiences

    Given the shift in perception of wastewater treatment plants as water resource recovery facilities, conventional mathematical models need to be updated. The resource recovery perspective should be applied to new processes, technologies and plant layouts. The number and level of models proposed to date give an overview of the complexity of the new plant configurations and provides a wide range ...

  • Evaluation of virus reduction efficiency in wastewater treatment unit processes as a credit value in the multiple-barrier system for wastewater reclamation and reuse

    The virus reduction efficiency of each unit process is commonly determined based on the ratio of virus concentration in influent to that in effluent of a unit, but the virus concentration in wastewater has often fallen below the analytical quantification limit, which does not allow us to calculate the concentration ratio at each sampling event. In this study, left-censored datasets of ...

  • A two-step approach for copper and nickel extracting and recovering by emulsion liquid membrane

    The recycling of copper and nickel from metallurgical wastewater using emulsion liquid membrane (ELM) was studied. P507 (2-ethylhexyl phosphonic acid-2-ethylhexyl ester) and TBP (tributyl phosphate) were used as carriers for the extraction of copper and nickel by ELMs, respectively. The influence of four emulsion composition variables, namely, the internal phase volume fraction (ϕ), surfactant ...

  • Erratum: Water Science and Technology 72 (7): Development of a new wastewater treatment process for resource recovery of carotenoids, H. Sato, H. Nagare, T. N. C. Huynh and H. Komatsu, doi: 10.2166/wst.2015.330

    A new wastewater treatment process that involves coagulation, ozonation, and microalgae cultivation has been developed. Here, two challenges are discussed. The first was minimizing phosphorus removal during coagulation in order to maximize algal production. The second was to optimize microalgae cultivation; algal species that grow rapidly and produce valuable products are ideal for selection. ...

  • Characterization and application of surface-molecular-imprinted-polymer modified TiO2 nanotubes for removal of perfluorinated chemicals

    The removal of perfluorinated chemicals (PFCs) during wastewater reclamation is a great concern. However, the existing advanced treatment processes are inefficient for the removal of PFCs from secondary effluents of municipal wastewater treatment plants (WWTPs) because other coexistent pollutants with less environmental significance are removed simultaneously. Therefore, research on ...

  • Chemical fractionation and speciation modelling for optimization of ion-exchange processes to recover palladium from industrial wastewater

    Palladium is used in several industrial applications and, given its high intrinsic value, intense efforts are made to recover the element. In this hydrometallurgic perspective, ion-exchange (IEX) technologies are principal means. Yet, without incorporating the chemical and physical properties of the Pd present in real, plant-specific conditions, the recovery cannot reach its technical nor ...
