The Adsorb BioBag: Low-Cost, Nature-Based Water Treatment
The BioBag is an innovative, low-cost water purification solution developed by Adsorb. It consists of a breathable mesh bag filled with Adsorb’s proprietary grade of activated carbon, designed to foster the growth of beneficial, naturally occurring bacteria when floated in polluted water. Once biologically activated, the BioBag propagates and releases microbes that help bioremediate organic pollutants, improving water quality through a natural, self-sustaining process.
This simple yet powerful solution supports UN Sustainable Development Goal 6: Clean Water and Sanitation for All. Its simplicity, affordability, and passive deployment make it ideal for low-resource and decentralized water treatment applications.
Backed by the Water Technologies Demonstration Programme (WADER) under South Africa’s Water Research Commission, the BioBag has been successfully trialed in Johannesburg dams. Proof-of-concept studies confirmed its efficacy in reducing faecal coliform bacteria and odour, demonstrating its potential for scalable environmental impact.
The core innovation lies in the specialised activated carbon used –engineered by Adsorb to support microbial colonisation and pollutant degradation.

Adsorb Reef – PFAS Removal Solution
PFAS (Per- and Polyfluoroalkyl Substances) are persistent synthetic chemicals used in textile manufacturing, firefighting foams, non-stick cookware, and food packaging. Due to their environmental persistence, ability to bioaccumulate, and links to serious health risks – including cancer and endocrine disruption – PFAS have become a major concern for municipal water systems worldwide.
The core innovation lies in the specialized activated carbon used – engineered by Adsorb to support microbial colonization and pollutant degradation.
Key Benefits
- Proven PFAS adsorption using specialized GAC formulations
- Simple integration into effluent discharge points
- Supports regulatory compliance with emerging PFAS discharge limits
- Aligned with sustainability and public health objectives
How It Works
- Adsorb Ree granular activated carbon bags are strategically placed within a submerged gabion unit inside the effluent flume.
- As treated wastewater flows through the system, PFAS molecules are effectively adsorbed by the high-surface-area activated carbon.
- The system is passive, scalable, and designed for retrofit compatibility with existing wastewater
