HP5600——Phosphorus Removal Resin

Adsorption principle

1. Special high-efficiency adsorbent composition: 

The matrix is “polyvinylpyridine” and the adsorbent surface is modified with coordination exchange functional groups "- R (OH) n

2. Phosphorus removal mechanism:

- R(OH)n + n PO3- - RPO3n + n(OH)-

The surface of the adsorbent is electrically neutral and the mechanism is ligand exchange, not ion exchange.

The principle of ion exchange is as follows:

Ligand exchange is more effective compared to ion exchange and has a greater capacity for phosphate exchange.

3. Reasons for pH drop in the effluent after adsorption：

After regeneration, the special adsorption material needs to be washed and activated by acid to adjust the pH of the material to 2-3. Therefore, when the influent for adsorption is neutral, the pH of the adsorption water will decrease due to the acidic environment inside the material (the pH of the effluent may be 3-4).

Product advantages

①Excellent structural performance: rich nanopore channels, excellent hydraulic diffusion performance, ensuring efficient phosphorus removal.

② High-efficiency adsorption performance: fast adsorption rate and high activity for phosphate ions, high selectivity and adsorption precision, little interference from other coexisting anions.

③ High mechanical strength and stability: high mechanical strength of adsorbent, good stability, long service life.

④Economic and efficient: good processing effect, low operating cost, suitable for large-scale application.

Application effects

High adsorption selectivity and adsorption precision for phosphate ions. Total phosphorus content of adsorption effluent can be less than 0.2mg/L.
