Background and Context
Water is a fundamental resource, essential for human health, food security, and economic development. However, global water challenges are intensifying. The UN World Water Development Report 2023, released at the UN 2023 Water Conference in New York, highlights that between two and three billion people experience water shortages for at least one month per year, with projections indicating the global urban population facing water scarcity could double from 930 million in 2016 to 1.7–2.4 billion by 2050 (Imminent risk of a global water crisis). Additionally, in 2022, 2.2 billion people lacked access to safely managed drinking water services, and 3.5 billion lacked safely managed sanitation, underscoring the urgency for innovative solutions (Basic Information about Water Reuse).
Climate change exacerbates these issues, with increased droughts and floods altering water availability, particularly in regions like the Middle East and North Africa, identified as having the highest water stress (See where water is scarcest in the world). Aging infrastructure further complicates matters, leading to inefficiencies and contamination risks. Against this backdrop, water treatment technologies are evolving, leveraging advanced innovations to ensure safe, reliable, and sustainable water solutions.

IIoT and Smart Water Networks
The Industrial Internet of Things (IIoT) refers to the integration of sensors, devices, and software to collect and analyze data from industrial processes, including water treatment. Smart water networks, enabled by IIoT, allow real-time monitoring and control of water quality, quantity, pressure, flow, and leakage. This capability optimizes water distribution, reduces operational costs, enhances customer service, and improves environmental performance.
Key benefits include:
- Real-time Monitoring: Sensors detect issues like leaks or contamination instantly, with acoustic sensors and AI algorithms pinpointing leak locations, as seen in cloud-based solutions offered by startups (What Is Smart Water Management?).
- Predictive Maintenance: Data analysis predicts equipment failures, reducing downtime and maintenance costs, extending infrastructure lifespan.

- Environmental Impact: Reducing water loss through leak detection supports sustainability, crucial in water-scarce regions.
The use of 5G networks enhances data transmission, enabling near real-time responses, particularly in urban areas with high demand. This trend is transforming water utility operations, with potential for further innovations as technology advances.
Nanotechnology and Nanofiltration
Nanotechnology involves manipulating matter at the nanoscale (1-100 nm), offering novel materials for water treatment processes like filtration, disinfection, desalination, and remediation. Nanofiltration, a type of membrane filtration with nanosized pores, removes contaminants such as salts, organic molecules, viruses, and bacteria, reducing energy consumption and environmental impact compared to traditional methods.
Key applications include:
- Nanofiltration Membranes: Operate at lower pressures than reverse osmosis, with 3D-printed nanofiber membranes filtering water 10 times faster, as developed by a startup, enhancing efficiency (Innovations in nanotechnology for water treatment).
