WATER MEMBRANES RESOURCES

  • The best reverse osmosis (RO) programs are guided by a defined set of operating principles that provides operators with clear performance standards and a consistent framework for decisions.
  • 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.
  • As Europe edges closer to regulating the production of PVDF membranes — key contributors to the toxic PFAS, 'forever chemicals' — the water industry finds itself at a critical crossroads.

WATER MEMBRANES SOLUTIONS

  • Sludge Sucker

    The Sludge Sucker™ unit is a cable-driven sludge removal mechanism that provides cost-effective and efficient removal of lightweight sludges, such as alum or ferric hydroxide, or light iron and manganese precipitates from rectangular settling basins.

  • Toray MBR NHP-Series MBR

    As part of the Toray MBR series, the NHP (New High Performance) module features thin membrane flat sheets that are densely packed into easily interchangeable cassettes. These cassettes allow for a higher packing density than what was originally thought possible with flat plate designs. The thin membranes are also highly flexible and allow for more movement, resulting in increased vibrations during aeration. This helps dislodge sludge and improve cleaning efficiency, all with less energy use. 

  • High Capacity MBR Sewage Treatment System: WWT-1000+

    This compact, easy-to-operate newterra Membrane Bioreactor (MBR) system combines activated sludge biological treatment with our advanced MicroClear™ ultrafiltration flat sheet membrane technology. The self-contained, high capacity system is comprised of four ISO-certified 40' shipping containers (high cube) and requires an area of only 15 x 15 m (excluding equalization tank/lagoon and permeate storage).

  • PURON® MBR Series The design of our single-header ultrafiltration PURON membrane bioreactor changed everything. Energy-efficient and cost-effective, PURON MBR requires the lowest energy demand of all commercially available MBR modules.
  • Brackett Green® Double And Single Entry Drum Screen Over the last century a large variety of fine screen types and flow patterns have been developed for both raw water intakes and for preliminary treatment of municipal waste water.

The Orange County Water District (OCWD) has long been an innovative leader in indirect potable reuse. An integral component of its Groundwater Replenishment System (GWRS) – a 100 million gallon per day advanced water purification facility – is reverse osmosis membrane technology.
