PVDF (Polyvinylidefluoride) and PES (Polyethersulfon) membranes are the most widely used membrane materials for MBR applications.
Compared to PES membranes, PVDF membranes are characterized by a better permeability and an advanced pore distribution as well as higher chemical and mechanical resistance.
In particular, PVDF membranes have a significant better chemical stability against oxidizing materials.
A higher treatment concentration increases significantly the cleaning efficiency and helps to prolong cleaning cycles. The operating cost decreases and he economic lifetime increases.
Key Factors of MBR Membrane Quality
Membrane Pore Size
Supratec PVDF Membranes with excellent pore characteristics
Compared to typical, state of the art MBR membranes on the market, Supratec PVDF membranes have a nominal pore size of 0.03µm and consist of an extremely porous and homogeneous pore structure.
The excellent porosity and homogeneous pore structure of Supratec membranes compared to typical, state of the art membranes on the market can be clearly seen und the electronic microscope :
