Investigating the effects of colloid ejaculation mass of reverse osmosis membranes and their mechanism

Abstract

In this paper, the effects of physical and chemical interactions on the rate of clamping of acetate cellulose (CA) membranes and aromatic polyamides have been described. The research results show that the colloid eclipse rate increases with increasing ionic strength of the solution, the concentration of colloid feed water and the water discharge of the membrane output. This indicates that the colloidal eclipse is controlled by a relationship between permeation elongation and two-layer electrical repulsion. As a result, the colloid eclipse has a direct relationship between the membranes of the osmotic system and the physical and chemical interactions. For natural water samples, permeability is much more important than chemical interactions, and permeability is the main controller for the rate of colloidal sting. In addition to the permeability, the surface structure of the membrane also has a significant effect on the membrane fouling phenomenon. Regarding the results, it can be seen that roughness or surface fineness can also affect the type and amount of eclipse.
