Laboratory Demonstration

Watch our innovative two-stage wastewater treatment process in action, demonstrating real-time pollutant removal and fluorescence detection of metal ions.

Our Innovation

We have developed a revolutionary two-stage functional material that can simultaneously remove organic pollutants and five types of heavy metal ions from industrial wastewater while detecting these ions through a cyclical process. Our solution stands out for its simple operation, cost-effectiveness, environmental friendliness, and sustainability.

The composition of industrial wastewater is complex and varied, with pollutant concentrations reaching up to 50 micrograms per liter in industries such as chemical, pharmaceutical, and electroplating. Our innovative material effectively addresses these challenges while significantly reducing treatment costs and eliminating secondary pollution risks.

Two-Stage Treatment Process

Stage 1: Organic Pollutant Removal

Stage 1: Organic Pollutant Removal Process Diagram

Process

Our polymer, encapsulated in a semi-permeable membrane bag, reacts with organic pollutants such as ethylene glycol, ethanolamine, and ethylenediamine. These pollutants are captured within nanoparticles that remain safely contained in the membrane bag while allowing water to pass through.

Performance

Achieves over 90% removal efficiency for organic pollutants, reducing concentrations to less than 1 mg/L, meeting discharge standards.

Stage 2: Heavy Metal Removal

Stage 2: Heavy Metal Removal Process Diagram

Process

The nanoparticles formed in Stage 1 react with five types of metal ions (Mn²⁺, Gd³⁺, Ni²⁺, Mg²⁺, and Fe³⁺), forming insoluble precipitates while exhibiting distinct fluorescence changes. The process automatically regenerates the polymer for continuous reuse.

Response Times

  • Ni²⁺: 2 seconds
  • Fe³⁺: 10 minutes
  • Gd³⁺: 30 minutes
  • Mn²⁺: 1-2 hours
  • Mg²⁺: 4 hours
