Utilizing luminescent bacteria and advanced membrane technologies, the design efficiently transforms polluted seawater into safe drinking and domestic water, addressing critical water scarcity issues.
5 key facts about this project
01
Utilizes luminescent bacteria to enhance water purification.
02
Incorporates multiple types of semipermeable membranes for efficiency.
03
Design allows for remote control and automation of purification processes.
04
Features a dual output system for domestic and drinking water.
05
Focuses on environmental sustainability and the extraction of radioactive substances.

The design focuses on a purification device that treats polluted seawater, changing it into usable resources for domestic and drinking water. This project addresses the issue of growing water scarcity, aiming to find practical solutions to environmental concerns. The design integrates advanced technology with a structure that is both functional and engaging, promoting public interest in the purification process.

Purification System Components

The purification device diagram shows several key components, including a water inlet, raw material liquid, and pressure control and auxiliary regulator. It features various types of semipermeable membranes, particularly microfiltration, ultrafiltration, and reverse osmosis. These membranes work together to efficiently separate and purify seawater, creating distinct sources for domestic and drinking water. Additionally, the design acknowledges the potential removal and solidification of radioactive substances that may be present in seawater.

Technological Integration

A significant focus of the design is the use of advanced technologies. Membrane separation and biomembrane technology play crucial roles in the purification process. The system also incorporates luminescent bacteria, which enhance both functionality and visual appeal. This automated and remotely controlled design represents a modern approach to water purification, blending technology with creative expression to engage the public in its operation.

Spatial Organization

The project includes detailed section views and floor plans that illustrate how the space is arranged. The internal layout is designed to optimize workflows while allowing easy access for users and visitors. This thoughtful spatial organization balances practicality with user engagement, making the purification system approachable and informative for anyone interested in its operation.

Design Detail

The incorporation of semipermeable membranes as a central material underscores the commitment to finding innovative water treatment solutions. These membranes are essential for achieving effective purification outcomes. As the system operates, it displays a harmonious balance of function and design, highlighting the important conversation around water quality and sustainability.

Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
