Under the dual pressure of industrial production and environmental protection, fluoride-containing wastewater treatment technology has attracted unprecedented attention. Traditional defluorination processes, such as chemical precipitation and flocculation, while solving some of the issues, often suffer from low efficiency, high costs, and complex operations.
Southwind offers an innovative solution with its new nanotechnology-based fluoride removal resin, HP3500, which provides precise treatment and stable compliance with standards.
HP3500 is an organic-inorganic nanohybrid adsorption material. It utilizes the Donna membrane effect, where surface groups on the polymer material pre-concentrate fluoride ions. These ions are then removed by fluoride-absorbing nanomaterials within the polymer, achieving high selectivity and adsorption precision for fluoride ions. The material’s rich nanopores and excellent hydraulic diffusion properties ensure rapid defluorination

Southwind Core Process Advantages
Fully Automated Control:
HP3500 resin enables fully automated, unattended control, greatly reducing labor costs and operational complexity. This automation ensures consistency in the treatment process and minimizes the need for constant manual intervention.
Low Operational Costs:
The desorption solution used for regeneration can be reused multiple times, significantly lowering operational costs. This recyclability of the desorption solution contributes to overall cost efficiency.
High Adsorption Capacity:
Due to its use of nanomaterial-based resin particles with large pore structures, the HP3500 resin has an excellent surface area, which results in a high adsorption capacity. This makes it highly efficient in removing fluoride ions from wastewater.
Stable Treatment Effect:
The HP3500 resin ensures that fluoride ions are removed to very low concentrations, maintaining consistent and stable treatment performance over time. This stability is crucial for ensuring that the effluent meets environmental discharge standards or reuse requirements.

Ligand Exchange Efficiency:
The ligand exchange process offers better performance than traditional ion exchange, providing a higher exchange capacity for fluoride ions. This leads to more efficient removal and better overall fluoride treatment.
Higher Selectivity and Stable Performance:
The resin has excellent selectivity for fluoride ions, ensuring effective removal with stable treatment performance. The effluent quality remains consistent, and operational costs are kept low.
Simple Regeneration Process:
Desorption only requires a basic sodium hydroxide (liquid alkali) solution, making the regeneration process simple. Additionally, no aluminum (Al³⁺) ions are introduced as impurities, ensuring the treated water remains free from unwanted contaminants.
Strong Resistance to Interference:
The resin exhibits excellent resistance to interference from other ions such as calcium (Ca²⁺), magnesium (Mg²⁺), sulfate (SO₄²⁻), and chloride (Cl⁻), which ensures the selective removal of fluoride ions without being affected by these common wastewater components.
Purity of Desorption Wastewater:
The desorption wastewater contains only sodium fluoride (NaF) and sodium hydroxide (NaOH), allowing for simple and efficient treatment. The fluoride-rich waste can be further processed to produce relatively pure calcium fluoride (CaF₂) products, reducing environmental impact and improving resource recovery.
