German Research Team Uncovers the Hydration-Shell Mechanism Behind Nanofiltration Removal of Glyphosate

Thanks to their heat resistance, acid/alkali tolerance, and high mechanical strength, ceramic membranes have long been regarded as “specialty membranes,” and in the past, because of their high price, were mainly used in budget-rich sectors such as oil and gas fields and specialty chemicals. In 2026, with advances in fabrication and the release of production capacity, ceramic membranes are moving from “specialty” toward “general-purpose,” opening space in broader scenarios such as municipal wastewater advanced treatment and food-and-beverage sterilization.

Falling cost is the key catalyst. Taking the 1850 mm ceramic membrane element as an example, after domestic capacity was concentrated and released, its price has dropped to about 60% of imported products, significantly narrowing the price gap with organic polymer membranes. Thinner ceramic separation layers, new sintering methods, and material formulations improve permeability while preserving mechanical strength; and because ceramic membranes often last more than ten years, their economics improve further when viewed over the full life cycle.

In performance terms, pilot data for ceramic ultrafiltration membranes in municipal wastewater membrane bioreactors are striking: flux stability far outperforms organic membranes, and more than 90% of flux can be recovered through online air–water backwash, effectively eliminating the nuisance of frequent chemical cleaning. For industrial wastewater containing high temperature, strong acid/alkali, or oily and abrasive substances, ceramic membranes are not easily damaged by aggressive cleaning chemicals, nor do they age rapidly under extreme pH the way organic membranes do — making them especially suitable for the chemical, mining, food, and dairy industries.

At industry exhibitions (such as IFAT Munich 2026), ceramic membrane filtration technology was featured as a high-durability, high-efficiency, sustainable solution, emphasizing its stability in long-term operation and low environmental footprint. Analysts argue that once price is no longer a hard constraint, it is only a matter of time before ceramic membranes capture part of the organic-membrane market; yet their scaled adoption still depends on whether continuous manufacturing yield and standardized interfaces can be further matured. Overall, the “trickle-down” of ceramic membranes is giving more harsh-duty water-treatment projects a more durable membrane option.

From the application map, ceramic membranes’ penetration path shows a “point-to-surface” character: initially concentrated in oilfield reinjection and specialty chemicals — sectors willing to pay a premium for reliability — it is now spilling outward along two lines. One is municipal wastewater advanced treatment and MBR, trading long life and low cleaning frequency for lower overall O&M burden; the other is aseptic filtration for food and beverages and separation–concentration in dairy and brewing, leveraging steam-sterilizability and inertness to build compliance advantages. The industry cautions that ceramic membranes, good as they are, are not universal: in ordinary municipal feedwater that is low-salinity, low-temperature, and weakly corrosive, organic membranes remain cost-effective thanks to lower upfront cost. The real selection logic should be “choose the membrane by duty,” not “judge merit by material.” As domestic capacity keeps pushing the price curve down, the boundary between ceramic and organic membranes will be set more by duty than by cost.
