NX Filtration starts pilot with IWE for water reuse from paper mills
NX Filtration, a global provider of direct nanofiltration technology for pure and affordable water, has started a pilot project with Industriewater Eerbeek (IWE), a subsidiary of three Dutch paper mills focusing on wastewater treatment. The objective of the pilot is to enable the reuse of wastewater, reducing the extraction of groundwater and the overall water footprint of the paper mills.
IWE has been purifying surplus process water from three paper mills (Folding Boxboard Eerbeek BV, DS Smith Paper De Hoop Mill and Neenah Coldenhove BV) in Eerbeek, the Netherlands, since 1960. With a strong focus on achieving a circular process, IWE seeks to use NX Filtration’s direct nanofiltration membranes for upgrading the wastewater stream to enable reuse as process water at the paper mills.
Research finds PFAS – the ‘forever chemical’ – is a prevalent indoor air contaminant
The air we breathe in our homes, schools, and workplaces can be polluted with harmful PFAS chemicals, according to a study published in the journal Environmental Science & Technology Letters. A new measurement technique developed by the research team detected PFAS chemicals in the air of kindergarten classrooms, university offices and laboratories, and a home—some with levels as high as those measured at an outdoor clothing company and carpet stores selling PFAS-treated products. The results suggest indoor air is an underestimated and potentially important source of exposure to PFAS, particularly for children.
“Food and water are known to be major sources of PFAS exposure,” said Rainer Lohmann, senior author of the study and professor of oceanography at the University of Rhode Island. “Our study shows that indoor air, including dust, is another source of exposure to potentially harmful forever chemicals. In fact, for children in homes or schools with old PFAS-treated carpets, inhalation may be even more important than dust as an exposure pathway to volatile PFAS that eventually could biotransform to more persistent and harmful PFAS.”
By affixing polyethylene sheet samplers to ceilings, the scientists measured volatile PFAS chemicals in the air of nine carpeted kindergarten classrooms, one home, and the storage room of an outdoor clothing store in California; as well as two laboratories, five offices, one classroom, one storage room, and one elevator at the University of Rhode Island; and two carpet stores, also in Rhode Island. PFAS were detected in the air of nearly every location.

New research shows the interaction of water aerosol with nanofiber mesh facemask material
Facemasks made with nanofibers have drawn increasingly more attention because of their higher filtration efficiency, better comfort, and lower pressure drop. However, the interactions and consequences of the nanofibers and microwater droplets remain unclear.
New research published in the journal Physics of Fluids shows the evolution of fibers made of polymers with different contact angles, diameters, and mesh sizes under water aerosol exposure is systematically visualized. The images show that capillarity is very strong compared with the elasticity of the nanofiber. The nanofibers coalesce irreversibly during the droplet capture stage as well as the subsequent liquid evaporation stage. The fiber coalescence significantly reduces the effective fiber length for capturing aerosols. The nanofiber mesh that undergoes multiple droplet capture/evaporation cycles exhibits a fiber coalescing fraction of 40%–58%. The hydrophobic and orthogonally woven fibers can reduce the capillary forces and decrease the fiber coalescing fraction.
This finding is expected to assist the proper design, fabrication, and use of face masks with nanofibers. It also provides direct visual evidence on the necessity to replace face masks frequently, especially in cold environments.

IDA World Congress postponed to Oct. 2022 to align with Australia’s COVID-19 reopening plan
After close consultation with the Australian government and based on the government’s COVID-19 vaccination and border reopening four-stage plan, the 2022 IDA World Congress, scheduled for May 29-June 2, 2022, has been postponed to October 9-13, 2022, to ensure an in-person event.
Accordingly, the International Desalination Association has extended the abstract submission deadline to February 15, 2022. The congress remains in Sydney, Australia, at the International Convention Center (ICC Sydney). “We can’t wait to welcome the world’s leading minds on water desalination and reuse to Sydney next year, as borders reopen, and our international visitors once again return. Our water community is certainly looking forward to networking and collaborating on new water solutions face to face with their global peers”, said BESydney CEO, Lyn Lewis-Smith.
The congress features a technical program covering all aspects of desalination and water reuse solutions to ensure water sustainability. With over 300 papers among 10 technical topics and multiple sub-topics, the technical program will explore a broad range of desalination and water reuse technologies, practices, and experiences worldwide. The program’s knowledge-sharing aspect recognizes that resources and requirements vary based on need, location, climate conditions, and natural resources. The Innovation Forum, a new feature of the congress, is a pitch-based competition limited to eight teams with a monetary award.
The IDA World Congress is supported by the University of Technology Sydney – Centre for Technology in Water and Wastewater, Australian Water Association, the Government of New South Wales, Sydney Water, Sydney Desalination Plant, UNESCO Centre for Membrane Science and Technology at the University of New South Wales, and the Water Services Association of Australia.

New study confirms air purifiers improve air quality by +60% indoors
The quality study was conducted in Spectrum Engineering offices, both before and after the Camfil City M air purifier had been running for 60 minutes. The experiments found the City M air purifier was able to improve air quality by 63% for even the smallest airborne contaminants. Meanwhile the City M was also able to reduce aerosol concentrations by 98.2% after only a 20 minute period.
A new study by Camfil Ireland in conjunction with Spectrum Engineering has found Camfil’s City M air purifiers can improve air quality and reduce aerosol concentrations indoors by more than 60%.
The research also found that the City M air purifier removed volatile organic compounds (emitted as gases from solids or liquids) from the enclosed area. The results of these experiments show that Camfil’s City M air purifier has the power to greatly reduce the presence of airborne particles that in some cases can prove life threatening.
Research by The European Environment Agency has shown air pollution is the single greatest environmental health risk in Europe. According to Camfil, High Efficiency Particulate Air filtration (HEPA) technologies are capable of greatly reducing the circulation of airborne particulate matter by over 99 percent.
“With thousands of students heading back to school this week and many back into the office we have an opportunity to provide clean and safe indoor air for all,” said Paul Flanagan, managing director of Camfil Ireland. “We have been actively committed to educating the public about the importance of clean air and to providing top quality solutions to protect people, processes and the environment for decades. The past year and a half has made our mission and purpose more important than ever before, as the idea of clean air has become a top priority for people. We are determined to show people that installing HEPA filters onto buildings can and will decrease the risk of inhaling harmful pollutants. This study by Camfil and Spectrum Engineering is proof of that success.”
“The COVID-19 pandemic has led to an increase in requirements for air quality improvements from our clients across the country,” said Brian O’Connell, managing director of Spectrum Engineering. “These tests validate the use of air cleaners to help improve air quality in buildings and help protect people from airborne contaminants.”
