Municipal Drinking Water


Water resources for municipalities in high-growth regions are under significant stress due to population growth and increased reliance on challenging source waters.

Climate change and extreme weather events further exacerbate the variability and quality risks of surface water sources, leading to frequent operational disruptions. Additionally, stringent regulatory requirements make it difficult to consistently meet quality and quantity goals with conventional water treatment processes. Existing facilities in metropolitan areas are often constrained in space, limiting their ability to expand or upgrade.

Nanostone’s Ceramic Ultrafiltration Membranes offer an innovative solution to the challenges of seawater desalination.

  • Compact Footprint: Ideal for high-growth regions with limited space, offering a smaller filtration process footprint.
  • Simplified Treatment Scheme: Requires only a compact inline coagulation process, reducing overall footprint and complexity.
  • Robust Operation: Ensures consistent treated water quality despite variability in surface water sources.
  • Increased Recovery: Higher recovery rate than alternatives, leading to increased uptime and lower operational expenses.
  • Carbon Reduction: Likely carbon reductions through the extended life of membranes, minimized footprint, and reduced need for extensive onsite infrastructure.
