  • Recreational Water

    Natural waters can be a hub for fun, recreation and sports. Ensuring their safety is critical, as microbial contaminants can pose serious public health risks. Traditional water testing methods often struggle to provide timely and continuous monitoring. Implementing advanced, automated technology not only enhances monitoring programs, but also helps to identify and mitigate potential hazards in a timely manner, ensuring that our recreational waters remain safe and enjoyable for all.

  • Drinking Water

    Access to drinking water is a major global issue, supported by the United Nations' Sustainable Development Goals. Providing safe drinking water involves a number of steps - collection from groundwater, surface water or recycled sources, treatment and disinfection, storage and distribution. This task is fraught with challenges, especially the need to comply with stringent regulations and the inherent complexity of water treatment processes. New-age automated monitoring technologies are helping to ensure water safety, facilitating real-time analysis and improving decision-making.

  • Wastewater

    Wastewater management, which includes the collection, treatment, and reuse of wastewater, plays an essential role in protecting public health and reducing the risks of pollution and flooding. Wastewater can be of domestic, industrial or agricultural origin and is typically treated in wastewater treatment plants. However, the challenges posed by aging infrastructure, urban population growth and climate change have a direct impact on the efficiency of these processes. It is becoming essential to integrate continuous monitoring within and downstream of treatment plants in order to assess treatment efficiency, optimize processes and ensure total compliance.

  • Digital Cities

    In the modern urban landscape, the concept of a “Digital City” is quickly becoming a transformative vision. These digitally enhanced cities seamlessly integrate traditional infrastructure with cutting-edge digital solutions to improve the quality of life for their residents. Beyond the implementation of digital technologies, a Digital City innovates with smarter transportation systems, improved water management, and energy-efficient buildings. They resonate with a responsive city government that prioritizes safety and the evolving needs of an aging population. In addition, by harnessing the power of information and communication technologies, Digital Cities offer improved efficiency, promote sustainability, and enhance overall quality of life. With tools such as IoT and autonomous systems, cities are stepping into a future where operational efficiency meets sustainable urban living, creating environments that are not only livable, but thriving.

  • Oceanography

    Oceanography is the study of the oceans, their physical properties, chemical composition, biological life, and geological makeup. It is a vast and complex field of study, and it is essential to our understanding of the Earth system and its climate. It helps us to understand how the oceans interact with the atmosphere, how they regulate the Earth's temperature, and how they are affected by climate change. To effectively navigate this vast field, researchers rely on advanced instrumentation. This instrumentation allows them to conduct detailed microbiological analysis, precise sampling, and thorough ecosystem mapping. From the shimmering coastal areas to the mysterious oceanic depths, having the right tools is essential to unraveling the many layers of our oceans and ensuring a full understanding of their ever-evolving dynamics.

  • Agriculture

    Water is a pivotal element of agriculture and must be closely monitored to protect human health, animal welfare and environmental integrity. Bacterial contamination of water can cause illness in humans and animals, significantly impacting food and livestock safety and productivity. In addition, unchecked bacteria can harm the environment by causing algal blooms or fish kills. With a global population expected to reach nearly 10 billion people in 2050, ensuring sustainable agriculture and production is imperative. The use of advanced, automated and IoT-connected microbiological analysis tools enable real-time tracking and prevention, ensuring that our agriculture remains safe, productive, and environmentally friendly.

  • Process Water

    At the beating heart of industrial facilities, water plays a central role, powering essential manufacturing and cleaning functions. Ensuring the purity of this water before it is discharged is critical not only for environmental protection, but also for operational efficiency and regulatory compliance. The days of manual sampling and waiting for third-party lab results are behind us. Today, with increased regulatory requirements and heightened public awareness, immediate access to water quality data is essential. Modern, real-time monitoring systems powered by IoT and automated technologies offer a proactive approach. This not only protects against potential shutdowns, but also optimizes processes, reduces costs, and ensures compliance. In an era where every drop counts, comprehensive water quality monitoring in industrial processes is key to sustainability, efficiency and safety.

  • Citizen Science

    New autonomous networked technology enables powerful Citizen Science approaches by providing a user-friendly data-driven solution that integrates instrumentation, communication infrastructure and cloud-based visualization.

At Fluidion we strongly believe that technology has a key role to play in our strategy toward a sustainable planet. The choice of the e-Chem V2 means a direct approach to the following United Nations Sustainable Development Goals:


e-CHEM Legacy

The e-CHEM Legacy analyzer, a groundbreaking product from Fluidion, represents a revolution in water quality monitoring. Its development was supported by the prestigious NSF-funded SBIR program, which recognized its potential to address global water quality concerns. Beginning with Phase I, the analyzer proved to be a game-changer - providing high-resolution, automated, in-situ measurements of multiple contaminants, from nutrients to chlorine and more. Phase II marked the product's path to commercialization. Rigorous optimization for user operations and adaptation to harsh environments expanded its applications. During this phase, e-CHEM demonstrated its superior sensitivity and accuracy, meeting and exceeding traditional laboratory capabilities. In a pivotal collaboration with the Los Angeles Department of Water and Power (LADWP), the e-CHEM Legacy endured a 4.5 year pilot operation. It successfully detected nitrification trends and provided real-time water quality insights, demonstrating a strong linear correlation with traditional measurements.

The e-CHEM Legacy has been upgraded to become the e-CHEM V2.
