INDA Adds Policy Expert to Government Affairs Team
INDA, the Association of the Nonwoven Fabrics Industry, announced that experienced policy expert Kevin Conroy has joined the association’s government and regulatory affairs staff as Senior Manager of Government and Regulatory Affairs.
Conroy brings extensive experience in government, politics, and public service to his new role at INDA. He most recently served on the staff of former Maryland Governor Larry Hogan, where he held multiple senior positions over the course of Hogan’s eight years in office, including Director, Chief of Staff, and Assistant Secretary of Agriculture for the State of Maryland.
“We are excited to welcome Kevin to the INDA team,” said INDA President Tony Fragnito, “his wealth of experience will expand our government and regulatory affairs impact at the state and federal levels while positioning INDA for even more proactive advocacy for the nonwovens sector.”
Conroy began his career on Capitol Hill in the office of Congressman Chris Shays before working for Congressman David Dreier and the House Rules Committee. He has managed numerous political campaigns at both the state and federal levels, building coalitions and executing successful strategies in competitive races.
“Kevin’s wealth of experience will allow us to hit the ground running on several issues important to the industry, including EPA rulemaking, state and federal PFAS and chemical regulations, and plastics,” added Wes Fisher, INDA Director of Government Affairs.
With a career spanning legislative, executive, and electoral arenas, Conroy brings a deep understanding of public policy, intergovernmental affairs, and political strategy to his new position at INDA. He will be working on the INDA team out of the greater Washington, D.C. area.
Aquaporin Achieves up to 20% Energy Savings in Singapore
Aquaporin has successfully completed the Living Lab Project to develop the world’s first biomimetic low-energy Aquaporin Inside® CLEAR membrane at demonstration scale. The membranes were installed at the Kranji NEWater Factory (KNF), operated by PUB, Singapore’s National Water Agency. After 12 months of continuous operation benchmarked against parallel concurrently operated trains with other commercial membranes, the Aquaporin Inside® CLEAR biomimetic membranes have achieved up to 20% energy savings for the energy-intensive reverse osmosis treatment stage, while consistently meeting the stringent water quality standards of NEWater. The demonstration project marks a major step forward in the potential use of biomimetic membrane technology for the NEWater treatment process in Singapore.
Dr. Gurdev Singh, PUB’s Chief Engineering & Technology Officer, commented, “At PUB, we recognize that the future of water management lies in meaningful collaborations. We actively seek to partner with industry players who share our vision of innovation and sustainability. By working hand-in-hand from the early stages of planning and conceptualization, to the deployment of innovative technologies, we can transform promising ideas into robust solutions that serve Singapore’s water needs whilst creating opportunities for growth in the water sector.”
Klaus Juhl Wulff, CFO of Aquaporin and CEO of Aquaporin Asia, added: “We are really proud of our work in the Living Lab Project. Achieving energy savings of this magnitude, while maintaining consistent water quality during the NEWater treatment process, underscores the real-world application and positive impact of our biomimetic technology. PUB has been an exceptional partner, and this outcome is a testament to what we can accomplish together through a shared vision.”
3D printed Filter Research Removes up to 85% of Greywater Pollutants
Researchers from Khulna University of Engineering and Technology (KUET) have developed a 3D printed honeycomb filter made to treat greywater from domestic sources.
The filter was produced on an Ultimaker FFF 3D printer, using virgin nylon filament blended with recycled material obtained by depolymerizing discarded nylon fabric, then coated with titanium dioxide nanoparticles. Nylon was selected for its chemical resistance, strength, and durability under repeated exposure to wastewater, making it more suitable than other common 3D printing materials such as PLA, ABS, or PETG.
Led by Sumit Kanti Saha from the Department of Textile Engineering, the project also saw contributions from Jashore University of Science and Technology. Published in Micro & Nano Letters, the work explores a low-cost, reusable option for non-potable water applications. While the results are promising, the team notes that further refinement is needed before the design could meet drinking water standards.

DuPont Membrane Technology Deployed in New Zealand
In collaboration with the Waikato District Council, Watercare, a public water utility in New Zealand has selected DuPont™ MemPulse™ membrane bioreactor (MBR) and OxyMem™ membrane aerated bioreactor (MABR) technology for a new 6.0 MLD wastewater treatment plant to serve the community of Raglan in the District of Waikato in New Zealand. This will be the first deployment of OxyMem™ MABR modules in the country—marking a significant milestone in the adoption of advanced wastewater treatment technologies in New Zealand.
In addition to enabling greater automation and reducing on-site personnel requirements, this multi-tech modular solution can provide compliance with New Zealand’s stringent discharge regulations and provide additional treatment capacity to future-proof the plant.
Raglan’s existing wastewater treatment plant combines an oxidation pond system with ultra-violet (UV) treatment before the treated wastewater is discharged into the sea on the outgoing tide. The treatment upgrade to MemPulse™ MBR and OxyMem™ MABR is the first step in removing the connection to the harbor. The clear water permeate discharge from the new treatment plant has helped gain support for a regenerated land-based discharge.
The decision to combine MemPulse™ MBR, which can provide the plant with high quality effluent, with OxyMem™ MABR will help Watercare achieve a lower total nitrogen concentration, making this community preference for land discharge viable.
