Marianne Walch

Title: Marianne Walch: Inventor of Bioreactor and Biofouling-Control Technologies.

Introduction

Marianne Walch is an inventor associated with Millsboro, Delaware. Her two patents address experimental bioreactor design and the prevention of biofouling on surfaces exposed to water.

Latest Patents

Walch’s patent, “Operationally Enhanced Bioreactor,” describes a vertically elongated housing designed to support biofilm growth on glass beads and slides. Testing ports allow researchers to evaluate the biofilm, while the slides can be withdrawn under controlled conditions to avoid damage. The housing’s high length-to-width ratio is intended to enhance aeration.

Her patent, “System for Preventing Biofouling of Surfaces Exposed to Water,” describes using acoustical shock waves to deter organisms from accumulating on submerged surfaces. Electrical sparks between adjustable electrodes generate the waves, with stored electrical energy discharged in short, remotely controlled cycles.

Career Highlights

Walch’s patent affiliations include the United States, as represented by the Secretary of the Navy, and Research Corporation Technologies, Inc. Her work reflects applications of invention in both biological research and the protection of water-exposed surfaces.

Collaborations

Her listed coworkers include David M. Stamper and Michael S. Mazzola, reflecting collaborative connections in her patent-related work.

Conclusion

Marianne Walch’s two patents demonstrate inventive approaches to studying biofilms and addressing biofouling, combining specialized equipment design with controlled acoustic technology.
