The recovery and recycling of surfactants from the retentate stream present both economic and environmental challenges. Efficient methods for surfactant recovery are essential to reduce operational costs and minimize environmental impact. However, current techniques for surfactant recovery often involve complex and energy-intensive processes, which can offset the benefits of MEUF in certain applications.

Lastly, scaling up MEUF technology from laboratory to industrial scale introduces additional challenges. These include maintaining consistent performance across larger membrane areas, managing increased volumes of retentate, and optimizing process parameters for continuous operation. The integration of MEUF with other treatment technologies to create hybrid systems also presents challenges in terms of process compatibility and overall system efficiency.

The competitive landscape for Triton X-100's impact on Micellar Enhanced Ultrafiltration (MEUF) techniques is in a growth phase, with increasing market size and technological advancements.
