Wastewater Recycling Articles

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 ...

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. ...

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 ...

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 ...

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. ...

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 ...

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 ...

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 ...

Continuous blowdown water (CBW) from industrial boilers is of great quantity and energy, and therefore worth recycling. According to the data from a long period of monitoring, carbonate and sulfate were documented as the main contaminants in CBW. Herein, an attapulgite (ATP) membrane was prepared on a macroporous Al2O3 support through solid state sintering. The prepared membrane ...
