WATER MEMBRANES RESOURCES

• Pretreatment Systems Enable Complete And More Economical PFAS Solutions

  For operators looking to optimize their PFAS removal systems, controlling the presence of dissolved organic carbon (DOC) offers an approach to minimizing operational costs due to granular activated carbon (GAC) reactivation and ion exchange media change-out.

• Reverse Osmosis Gets Smarter: New Technologies Target Energy Use And Membrane Fouling

  Nearly 45–60% of a reverse osmosis (RO) plant's operating cost is linked to energy consumption, while membrane fouling can reduce productivity by 15–40% and increase cleaning costs by thousands of dollars annually. The newest generation of RO systems is therefore focused on reducing energy demand, extending membrane life, and using intelligent monitoring to predict fouling before performance declines.

• Brine Valorization — The Future Of Desalination

  Brine valorization plants are the next step in the evolution of desalination technology which opens a new horizon for wider use of desalination as a baseline source of drought-proof and environmentally and fiscally sustainable water supply.
• Breakthrough Recyclable Polyimide Membranes Transform Wastewater And High-Salinity Water Treatment

  Researchers have developed polyimide-based membranes for membrane distillation (MD) that overcome three persistent issues in membranes for water treatment and gas separations: the need for pore-forming chemicals that prevent recycling, performance degradation due to pore wetting and fouling, and the inherent trade-off between high water flux and selectivity.

• A Market On Edge: PVDF's Uncertain Future And The Ceramic Alternative

  By classifying PVDF as a PFAS “forever chemical” and including it under the proposed restriction, the EU has introduced the prospect of a multi-billion-dollar technology shift. While the outcome will depend on the final derogation periods granted, the proposal creates a defined regulatory horizon for PVDF membranes and forces the global water industry to evaluate alternatives.
• How Industry Is Solving Its Water Supply Crisis

  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.
• Rural Water Treatment Plant Reduces TTHMs And HAA5 With Ion Exchange

  Both rural and urban water systems experience dissolved organic carbon (DOC) — a precursor to halogenated organic compounds like total trihalomethanes (TTHMs) and haloacetic acids (HAA5) — in source water. However, rural systems often struggle to find treatment options suited for smaller scale operations and budgets.

• New Research Could Extend Membrane Life And Lower Desalination Costs

  As water-scarce regions clamor for answers, developments in membrane anti-scaling bring desalination closer to viability.
• Silica Fouling In Reverse Osmosis Systems: Prevention And Treatment

  The control of silica fouling in reverse osmosis systems is crucial for maintaining system performance efficiency and longevity. It prevents costly downtime and membrane damage. This article provides practical knowledge on silica scaling in RO systems, its challenges, and effective control strategies.
