1. Project Background:

The treatment of various industrial wastewater streams, specific chemical processes, and energetic materials production often involves dealing with complex acidic or neutral water bodies. A defining characteristic of such water is the presence of high concentrations of sulfate (SO₄²⁻) and chloride (Cl⁻) ions. These ions severely interfere with the deep removal requirements for key target anions such as nitrate (NO₃⁻), perchlorate (ClO₄⁻), or radioactive pertechnetate (TcO₄⁻).

2. Process Stability Requirements

There is a need to achieve long-term, stable selective adsorption within a highly competitive ionic environment, avoiding frequent regeneration. Simultaneously, the resin must possess excellent physical and chemical stability to adapt to potential process fluctuations and prevent the generation of fines.

3. Solution: BAX01 Resin

To address the challenge of high background interference, a selective ion exchange process centered on BAX01 resin is employed. Thanks to its unique synthesis process, this resin exhibits significantly high selectivity for nitrate, perchlorate, and pertechnetate ions even in water with extremely high sulfate and chloride content. It effectively penetrates the interference, enabling precise capture of the target ions.

4. Application Performance

1. Deep Removal, Stable Compliance: In the presence of high concentrations of competing ions, the removal efficiency of BAX01 resin for the target anions is significantly superior to that of conventional resins. The effluent concentration can stably meet the most stringent limit requirements.

2. Efficient Operation, Cost Optimization: Its high selectivity extends the working cycle, reduces regeneration frequency and chemical consumption, and improves overall treatment efficiency and economy. Excellent mechanical strength ensures stable, long-term equipment operation with low maintenance costs.
