Researchers at the University of Technology in Sydney, Australia have developed a new catalytic technology that breaks down key contaminants, hydrogen peroxide and triazole, in water used for semiconductor manufacturing. Professor Long Nghiem and Associate Professor Cuong Ton-That, in partnership with Infinite Water International Australia, pioneered the research to streamline water recycling at manufacturers, helping to treat recycled water to the rigorous standards required to wash delicate components. The method is tailored to be implemented in existing wastewater infrastructure, and uses an oxidation agent to target contaminants, making the water safe for further use or for disposal.

The Industrial Water Solutions Conference, taking place in Columbus, Ohio from June 23-25, will feature a panel of industry experts from leading manufacturers, scientific institutions, construction and engineering firms, and utilities to discuss High Tech and Data Center Cooling. As the AI revolution drives demand for high-performance computing, water and energy use in data centers and semiconductor fabricators is increasing. Panelists will discuss innovative cooling strategies to address growing demand, focusing on leveraging water reuse for sustainable digital infrastructure.

The WateReuse Association welcomes Aquapolo Ambiental. Founded in 2009, Aquapolo is the largest water recycling plant in Latin America, and the fifth largest in the world, with a treatment capacity of over 260 gallons per second. Located in São Paulo, Brazil, Aquapolo services industrial facilities in the ABC Paulista region and currently serves nine clients and 14 industrial plants. Aquapolo was founded in response to regulations restricting industrial use of potable water in the region. With sustainability at the forefront of its mission, the operation saves one liter of drinking water for every liter provided to its industrial clients.

Last week, WateReuse Colorado held its annual conference at the Colorado State University Spur campus in Denver, drawing nearly 120 water sector professionals across Colorado, Arizona, Florida, and California to discuss barriers, opportunities, and challenges for implementation of water reuse in the West. Key discussions centered on Colorado reuse case studies, implementing reuse in small communities, contaminants of concern, and operations. The conference featured introductory remarks from WateReuse Colorado President Erik Jorgensen, WateReuse Interim Executive Director Brian Biesemeyer, and Professor Sybil Sharvelle from Colorado State University.

Beginning this month, Monterey One Water is recycling water from food processors in Salinas, rather than the water being treated for disposal. The agreement between Pure Water Monterey, City of Salinas, and Monterey One Water allows the water to be treated for recycling and stored in the Seaside groundwater basin for future use on the Monterey Peninsula without detracting from Salinas Valley's groundwater supply. The agreement will continue through October 2025 with the option for two six-month renewals. Salinas is enhancing its water treatment facility in response to industry growth and continues to collaborate with Monterey One Water to create alternative conveyance systems for treatment or recycling.

In 1918, the state of California developed the first water reuse regulations in the United States to help irrigate its booming agricultural sector. Since then, California has remained a global leader in water reuse. Today, California recycles over one million acre-feet of water each year to benefit people and the environment. That’s enough water savings to meet the indoor and outdoor needs of at least two million households! California communities are securing their water future by producing highly purified recycled water for drinking and recharging aquifers, as well as by expanding non-drinking water reuse for agriculture and irrigation and recycling more water within buildings. Check out the WateReuse California Profile in Reuse with simple facts, figures, and case studies – and share it with everyone from policymakers to students.

When Arizona adopted its Advanced Water Purification rules in March 2025, it opened the floodgates for a new generation of direct potable reuse projects. But the new rules also created a need for updated guidance on corrosion control. Simon Horsley, an expert with 20 years of corrosion control expertise, will explain how new processes can affect water chemistry and distribution systems. RO and non-RO treatment processes raise important considerations for product water corrosivity, influenced by the extent of RO treatment and post-conditioning processes. Horsley will review corrosion control requirements and guide water system owners in developing a corrosion control study (CCS) for systems supplied by Advanced Water Purification Facilities. Key topics include system characterization, DPR-specific corrosion risks, desktop evaluations of water quality shifts, demonstration testing approaches, and strategies for implementation and monitoring.

Water is the fuel of the new economy. The Industrial Water Solutions conference will bring together business and utility leaders for knowledge-sharing, networking, and collaboration. Industrial Water Solutions is the essential conference for professionals that provide, treat, manage, use, or regulate water in industrial settings to find solutions that turn waste streams into value streams. Participants will share strategies that increase resilience and ensure reliable water resources for both industry and the communities in which they locate.

Presented by WateReuse Association & Water Environment Federation
