High-Performance Boron Absorbents With Flexibility and Minimal Environmental Footprint

Boron is an essential micronutrient necessary for the growth and development of plants, animals, and humans, while also playing a critical role in industries such as manufacturing, agriculture, and semiconductors. However, while beneficial in trace amounts, excessive boron levels can be toxic. High concentrations in drinking water pose significant health risks, particularly to reproductive and developmental systems, while boron contamination in industrial water supplies can degrade process efficiency and product quality.

Current methods for boron removal, such as reverse osmosis and ion exchange, face significant limitations. Reverse osmosis struggles to remove boron efficiently, especially in seawater desalination, often requiring multiple stages and high energy consumption to achieve acceptable levels. Ion exchange resins pose low loading capacity and require massive harsh chemicals for regeneration. 

The proposed boron absorption technology provides a solution that efficiently removes boron from diverse water sources, including seawater and wastewater. It effectively reduces boron levels to meet stringent standards, such as drinking water limits of less than 0.5 mg/L. The technology aligns with sustainability goals, consuming fewer chemicals and exhibiting strong recovery stability. Additionally, the proposed absorbent is flexible, customizable and compatible with various water treatment applications.

The technology owner seeks partnerships to integrate this solution into existing water treatment systems or collaborate on industrial-scale demonstration projects to address boron contamination across multiple sectors.
