WATER MEMBRANES RESOURCES

  • 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.
  • 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 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.
  • 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.

  • 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.
  • 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.
  • 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.

  • As water-scarce regions clamor for answers, developments in membrane anti-scaling bring desalination closer to viability.
  • 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.

WATER MEMBRANES SOLUTIONS

  • Membrane Systems: Featuring Aqua MultiBore Membranes

  • microBLOX™ System

    microBLOX™ Membrane Bioreactor (MBR) systems are fully functional solutions to wastewater treatment problems and are ideally suited for a wide range of applications, including, but not limited to: housing developments, state parks, rest areas, isolated communities, military camps, shopping malls, golf courses, resorts, casinos, sewer mining (scalping), some industrial and more.

  • PASSAVANT® Tube Diffuser BIOFLEX®

    A tube diffuser BIOFLEX® consists of a support tube with an inside thread and slotted sleeve membrane. Two hose clamps fasten the membrane onto the support tube and an O-seal is applied for sealing between the distribution pipe and the diffuser element. To avoid buoyancy the support tube is flooded. Tube diffusers are usually installed in pairs either by a pipe clamp fixed on a round tube serving as a distribution pipe or by a double nipple inserted into a rectangular tube. When air is supplied, it is directed through the head of the support tube under the membrane. Through the slots of the membrane the air is smoothly dispersed into the wastewater.

  • Automatic Scraper Strainers Protect Critical Membrane Systems

    Automated scraper strainers pre-filter water and wastewater to protect fragile membrane systems from damage caused by large, suspended particles, reducing maintenance and replacement costs.
