Features of MegaVision’s UF membrane Modules
|
| |
Our UF membrane modules' hollow fibers are modified polysulfone which is being patented by Shanghai MegaVision with below features |
| |
Permanent hyrdrophilic
Higher anti-fouling properties against organic pollutants and excellent resistance to inorganic acids & alkaline
No electric charge which can bear flocculating agent with any charges
High fiber strength allow for long term service and maintaining filtration efficiency even after cleanings
Excellent hydrolytic and pH tolerant to fit majority of chemical cleanings
Excellent chemical resistance to tolerate feeds containing various contaminants
Control of pore size and pore distribution

 Permanently hydrophilicity (for steady flux) - the hydrophilicity of UF membrane is very important for anti-fouling and stable flux properties. MegaVision's UF membrane made by modified polysulfone, are intensively chemically and thermally treated with permanently hydrophilicity properties. During filtration, material like colloids, proteins, oil, etc, would form "spherulites agglomeration" precipitate onto the surface of our modified membrane unlike the phenomenon of "cake agglomeration and precipitation" took place at other compared membranes, these"spherulites agglomeration" have lower impact to filtration efficiency and allow our membrane to have longer service time and maintaining longer time intervals of cleanings. |

|
| |
Due to the reason that no electric charge on our membranes, this feature allows feed variation and pretreatment of flocculating agent with any charges. And this feature of our membrane demonstrates advantages in usage of in river water treatment or contaminated unknown quality feeds. |
| |
|
| |
Our membrane demonstrates strong fiber strength with high tensile strength, high impact strength, and high dimensional stability (no post shrinkage). This feature of strong fiber strength (or lower fiber breakage) and stable dimensional stability (no post shrinkage) of our membrane allow longer service time during filtration and maintaining longer time intervals for cleanings. |
| |
|
| |
Our membrane demonstrates permanent hydrophilic. With oven test at 100 ℃ for 48 hours, our membranes still maintain high filtration efficiency even though some of the fibers have been dried. This permanent hydrophilic feature allows significant reduce of pretreatment chemicals and operating flexibility. As a result, reduce cost of transportation, operating, and maintenance. |
| |
|
| |
The pore size and pore distribution of membrane are well controlled in order to achieve high quality filtration efficiency. Compared to other Polysulfone membranes, it's demonstrated that, for instance, our membrane is able to run at stable filtration condition of 70-125 L/hr with water quality of SDI < 2 for longer period of time. Higher service is also observed.
