5 macro trends in water technology & management at Aquatech Amsterdam 2025

It was a fulfilling experience to attend the 2025 edition of Aquatech Amsterdam & interact with innovators, practitioners & manufacturers to gain insights into where the direction of global water management is headed.

Here are the 5 key macro trends shaping the path to water security.

1. War on micro-pollutants:

Micro-pollutants are trace-level contaminants present in concentrations of micrograms per litre (µg/L) or even nanograms per litre (ng/L). Specifically, one subset of these micro-pollutants widely known as PFAS (Per and Polyfluoroalkyl Substances), has been the focus of many technological developments to breakdown or remove #PFAS. PFAS are found in firefighting foams, non-stick cookware (Teflon), waterproof clothing, food packaging, and industrial processes. Data on health risks to humans linked to PFAS is emerging rapidly. Current available data links PFAS to cancer, liver damage, immune system disruption, and developmental effects. PFAS also bioaccumulate in human and animal tissues. US & EU have recently regulated PFAS in water treatment. The treatment of micro-pollutants requires advanced technologies. Activated carbon adsorption, advanced oxidation processes (AOPs) using ozone / UV / or hydrogen peroxide are being developed. Membrane filtration, such as nanofiltration and reverse osmosis (using ceramic membranes), captures even trace-level pollutants.

2. Embracing modular technology for easy & quick deployment with rental options:

Companies are increasingly developing products which can be made modular with factory fitted & factory tested setup for quick and easy deployment at site. This approach reduces site gestation period allowing customer quick startup & commissioning of their equipment. A rental deployment approach is gaining popularity with customers which avoids upfront costs & keeps the technology providers engaged with the site for a longer period.

3. Enhancing membrane technology for energy efficiency & reduced fouling:

Water or wastewater treatment is essentially a separation process wherein contaminants or salts are separated from water; and globally, membranes are now the preferred choice of technology for separation for achieving the desired quality water. However, membranes still suffer from high operating costs due to energy consumption, cleaning (due to fouling) and frequent replacement due to short life. Companies & innovators are developing membranes which can address these shortcomings. Seawater desalination & treated wastewater reuse have been the holy grail of water security for several countries; but high energy costs of the membrane processes has been a roadblock, specially for developing countries. 3D printed membranes & also 3D printed membranes spacers have the potential to reduce the energy consumption. Similarly, advanced coatings (like zwitterions) help in reduced fouling & reduced frequency of replacement which helps in reduces the lifecycle cost of such systems making them more attractive for utilities.

4. Climate proofing water infrastructure:

Climate change is here & now; and water infrastructure globally is vulnerable to climate extremities. Companies & utilities are working on technological advancements & product development to mitigate climate impacts including flooding & droughts. More innovation will be seen to develop climate resilient infrastructure across the world. Strengthening water infrastructure is essential for adapting to climate change and ensuring long-term water security. By integrating nature-based solutions, flood-resistant structures, durable materials, and smart technologies, cities can build water systems that are both resilient and sustainable.

5. Harnessing AI & Digital Twins for smarter solutions:

Developments in AI are revolutionising water management by enhancing efficiency, conservation, and decision-making. Several utilities with the help of companies & start-ups are deploying AI-powered sensors which enable real-time monitoring of water quality, while machine learning models predict pollution and detect leaks in distribution networks. AI-driven hydrological models are being tried to forecast floods and droughts, improving disaster preparedness. Overall, AI is playing a crucial role in ensuring sustainable and secure water systems. Another aspect where AI is being used is in Digital Twins. Digital Twin is a virtual model of a physical object, system, or process that mirrors its real-world counterpart in real time. This digital replica uses data from sensors, IoT devices, and other sources to simulate, analyse, and optimise performance. Digital twins are being developed & tried by utilities to transform water management by providing real-time insights, predictive analytics, and simulation capabilities.
