New research from Yale University encourages discussions on how to implement circular economy systems on a larger scale Researchers at Yale University in New Haven, Connecticut, believe that circular economy systems are essential to our long-term survival on a planet with limited resources. While some large companies, including Google, Dell, Philips, and Unilever, and a few ...

Aeration accounts for a large fraction of energy consumption at conventional water reclamation plants (WRPs). Older plants were designed when control techniques were relatively primitive and energy consumption was less of a concern. As a result, although process operations at older WRPs can satisfy effluent permit requirements, they can operate with excess aeration. In this study, we developed ...

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 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 ...

Challenges are not unique to water and wastewater treatment, but the challenges thrown at operators and managers often require equal parts of thoughtfulness and creativity, with dashes of patience and persistence. This is why the industries are “home to some of the most ingenious professionals to be found in any industry,” according to an editorial in Treatment Plant Operator. ...

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 ...

As sustainability and water scarcity continue to be key issues for water managers worldwide, it’s more and more critical to find new solutions and technologies. Check out the laser cutter which is a great new technology invention.  Wastewater is a particularly abundant and potentially useful resource. In fact, teams of European researchers are working to harvest energy and recover ...

Namibia, an arid country in southern Africa, is plagued by drought and water scarcity. But, it’s also a country that continues to make progress in wastewater recycling after becoming an early adopter of the technology. The city of Windhoek’s Goreangab wastewater treatment plant is considered a pioneering facility in water reclamation. First constructed in 1968, the plant not only ...

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 ...

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 ...

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 ...

Many companies have opted to introduce a policy of zero liquid discharge production using our high-quality VACUDEST vacuum distillation systems. Users can reduce their consumption of fresh water – an increasingly dwindling resource – and significantly reduce their disposal costs by recycling their industrial wastewater. Read on to find out what our customers say about VACUDEST: Ovidio ...

Jet Aviation in Basel, Switzerland, is using a VACUDEST vacuum distillation system to efficiently and sustainably treat wastewater left over from refurbishing aircraft parts. This state-of-the-art system replaced outdated chemical/physical treatment at the company. Jet Aviation is particularly pleased with the high quality of the treated water, which can even be reused in maintenance processes. ...

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 ...

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 ...

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. ...

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 ...
