WATER REUSE RESOURCES

  • As water systems become more circular and complex, understanding and managing the subsurface — the hidden half of the water cycle — is becoming a critical enabler of resilience. This article explores the key trends shaping this new reality, from tackling “forever chemicals” to the water strategies redefining heavy industry.

  • Making Waves spoke with Bing Liu, Sales GM of Xylem’s Water Infrastructure business in China, about the country’s growing water reuse opportunity and one utility leader that is leading the way: Beijing Drainage Group.

  • To combat drought, Abilene, Texas, implemented a reuse system utilizing O3​ + BAC to remove trace organics. This solution met strict standards, ensured water resilience, and proved more cost-effective than AOP alternatives.

  • Researchers warn that California and other states affected by megadroughts — periods of drought lasting 20+ years — will have to accept this as the new normal. That means rethinking the water cycle and finding new, more sustainable water sources.
  • Because of our own decades-long mismanagement of our collective global water resources, we are now facing a global freshwater crisis where the demand for freshwater is predicted to exceed its supply by 40% by the year 2030. Directly coinciding with the water crisis timeline is the growing need for data center construction in order to accommodate AI, cloud computing, and other Big Data and IoT processing.
  • The business case for industrial water reuse has fundamentally shifted. Companies once evaluated these systems against environmental goals or regulatory compliance costs. Today, they're measuring them against operational risk and supply security — a calculation that increasingly favors reuse regardless of sustainability credentials.
  • Lessons in urban water management through water conservation, capture, and reuse.
  • In the heart of Israel’s Jezreel Valley, Ba’emek Advanced Technologies—part of the Tnuva Group—faced a critical challenge: how to sustainably reuse water extracted from whey during dairy processing without compromising safety or quality.

  • The wastewater treatment industry is quickly uncovering the usefulness of boiler feedwater for more sustainable operations. The advantages and applications are becoming more innovative and resourceful as more enterprises deploy consistent water reclamation practices.

  • Water is one of the most essential resources in any industrial setup, and managing it efficiently can mean the difference between success and stagnation. Welcome to the world of industrial water services — a sector that's as critical as it is complex.

  • Water Reuse: Solutions For Sustainability, Efficiency, And Resilient Water Systems

    What is water reuse?

    Water reuse is the process of treating and reclaiming water from various sources for practical purposes, including groundwater recharge, industrial applications, wetland restoration, agricultural irrigation, public access area uses, as well as drinking water applications. By reusing water, communities can reduce dependence on traditional water supplies, avoid costly imported water from 3rd party providers, and improve resilience in water systems. Thanks to progress in water treatment technology, along with economic and regulatory incentives, water recycling has become a cost-effective and sustainable solution to meet the growing demand for highly treated water and overcome supply shortages during droughts.

    There are three primary types of water reuse: Indirect Potable Reuse (IPR), Direct Potable Reuse (DPR), and Non-Potable. In IPR reuse systems, advanced treated water is either injected into an environmental buffer (groundwater, river, or reservoir) before being extracted again for use, whereas DPR is directly blended into the drinking water treatment plant or distribution system. Non-potable water is not intended for human consumption and can be used for irrigation, industrial processes, laundry, or toilet flushing.

    Advanced treatment technologies, such as membrane filtration, reverse osmosis, ultraviolet disinfection, ozonation, and advanced oxidation processes (AOP), play a crucial role in ensuring the quality and safety of reclaimed water.

    Why reuse water? 

    As water scarcity continues to rise, water reuse is an essential strategy for creating a more sustainable future. The use of recycled water reduces the demand for freshwater sources, which are becoming increasingly scarce due to population growth, climate change, and other factors.

    Here are some key benefits of water reuse:

    • Safeguard quality and resilience: Reused water is purified well beyond drinking water standards, improving resilience and ensuring quality for both potable and even non-potable purposes.
    • Uphold safety: Treatment processes like ozone and ultraviolet light can be used to disinfect or break down complex contaminants, ensuring water is pathogen-free and concentrations are below maximum contaminant levels (MCL).
    • Ensure cost savings and efficiency: After treating a waste stream to discharge level, it may require less treatment to bring it to reuse standards, making reuse not only environmentally responsible but also cost-effective in many scenarios and locations.
    • Conserve traditional water supplies: By reusing water, we can lessen our reliance on conventional water resources like rivers, lakes, and aquifers, thereby conserving them for future generations.
    • Reduce carbon footprint: Water reclamation is often more efficient than treating a raw water resource, which can lessen environmental impact.
    • Enable versatility and customization: Advanced treatment systems are tailored to meet specific needs for a variety of sectors, including industrial, urban, agricultural, and public access area uses.

    How to reuse water 

    The major aim of every reuse project is to minimize human health risk associated with the use or consumption of reclaimed water. While the exact treatment requirements depend upon the source water quality and the reuse purpose, to be cost-effective, the treatment must be energy efficient and have a high-water yield.

    An adequate treatment design plan depends on the application the water will be used in. In non-potable applications, normally filtration and disinfection will suffice, while potable reuse generally requires a combination of advanced treatment processes such as membrane filtration, reverse osmosis, disinfection, and/or advanced oxidation.

    Xylem has brands and solutions to fit every stage of the water reuse process:

  • Reducing And Reusing Water In Steel Manufacturing

    The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.
