here, I am looking for membrane that has a porosity less than 0.22 micrometer which can allow the diffusion of solvents through it with blocking the moments of microorganisms?
any suggestions are welcome!

Google is your friend. For example;
Whatman Anotop 10 syringe filter sterile, 0.02 μm, 50/pk

Dear Ramesh:
I would tend to stay away from some of the flat sheet membranes the issue of grow through and blow through dynamic is well established. A good quality hollow fiber UF or perhaps even a MF would do best. One of the cheapest UF are normally found in dialysis cartridges but also there are water specific membranes such as those made by varios manufacturers.
Dear krishana kumar and David Swiderski thank you very much for you suggestions, I will sure look into it. thanks
