RO Water Purifier Mechanism Model

There are several classic models for the unified "dry closed wet open" reverse osmosis mechanism model

1. Preferential adsorption capillary pore model: no pores were found under the weak point dry electron microscope. Wet film samples are not intended for electron microscopy.

2. Dissolution-diffusion model: porosity is not considered.

3. Dry closed wet open model: The most suitable modern reverse osmosis mechanism model proposed by Deng Yu et al. in the 1980s and 1990s can explain the 1 and 2 models. The "dry-closed-wet-open" reverse osmosis model unifies the two most classic reverse osmosis mechanism models, the pore model and the dissolution-diffusion model. This is

When the film is dry, the film shrinks and compacts, the pores are closed, and cannot be seen under the electron microscope;

When the membrane is wet, the membrane material swells, the pores of the membrane are swelled by the solvent, and the pores open. This combination is a "dry closed wet open" desalination model.
