Paragraph starter
The research by Castro and Abejón (2024) highlights the significant and growing interest in pressure-driven membrane technologies for the remediation of heavy metal-contaminated wastewater. Their bibliometric analysis reveals that while high-pressure membranes like reverse osmosis offer superior rejection rates, lower-pressure technologies such as microfiltration and ultrafiltration are being extensively investigated, particularly with advancements in incorporating embedded adsorbents to improve their efficacy for dissolved heavy metals. This suggests a design opportunity to develop hybrid or enhanced low-pressure membrane systems that balance performance, cost, and energy efficiency for industrial applications.
