FLOW Technology – Xoma’s innovative algae technology
As part of our commitment to sustainability, Xoma has developed FLOW, a cutting-edge solution for industrial water purification. FLOW harnesses the power of microalgae to remove pollutants and heavy metals from process water, providing industries with a cost-efficient and eco-friendly alternative.
FLOW utilizes microalgae-based filtration to efficiently remove contaminants such as copper, zinc, lead and other harmful substances from industrial wastewater.
Here's how it works
- Binding heavy metals (bisorption): The cell walls of the algae capture heavy metal ions through natural chemical processes, without the algae consuming energy.
- Uptake of metals (bioaccumulation): Algae actively take up certain metals inside their cells and destroy them.
- Metal transformation and precipitation: By secreting substances, algae transform heavy metals into insoluble compounds that can be easily separated from the water.
- Self-healing system: The algae grow and renew themselves, making the system both long-lasting and efficient.
