Per-Magnus Ehde

Per-Magnus Ehde is a Lecturer at the Academy of Entrepreneurship, Innovation and Sustainability at Halmstad University, where he works as a research engineer specializing in wetland systems. His academic career combines teaching responsibilities with active research in environmental engineering and wetland ecology.

Dr. Ehde's research focuses on the application of wetland systems for environmental protection and resource recovery. His work spans several key areas including nutrient removal from agricultural runoff, greenhouse gas dynamics in wetlands, biogas production from wetland plants, and the hydraulic performance of constructed treatment systems. He has published consistently since 2007, with recent work (2024-2025) continuing to address critical questions in wetland engineering and water quality management.

Ehde's research demonstrates a strong practical orientation, with publications frequently addressing how wetland design parameters affect treatment performance. His work on nitrogen removal efficiency, pharmaceutical attenuation, and long-term wetland performance provides valuable insights for environmental engineers and policymakers seeking sustainable water management solutions. Recent publications highlight innovations such as woodchip-based floating beds to enhance nitrogen removal and investigations into the balance between greenhouse gas emissions and biogas production potential in rewetted peatlands.

His scientific contributions reflect an interdisciplinary approach that bridges ecological principles with engineering applications, focusing on solutions for agricultural water management and sustainable resource use.
