New highly efficient membrane filter outperforms conventional crossflow membrane technologies
The superior performance of the PPG membrane is driven by advancements in material science made by PPG’s team of scientists and engineers. The proprietary manufacturing process allows a precise pore size which can be varied over the ultra and micro filtration ranges with a narrower pore size distribution compared to conventionally cast membranes.
A composite membrane is formed by combining a nanoporous, hydrophilic inorganic filler and a hydrophobic polymer. The hydrophilic nature of the high surface area inorganic filler creates strong capillary forces, pulling water through the membrane. The nanoporous structure reduces fouling by not allowing penetration of oil droplets or solid particles. This innovative morphology results in higher flux rates and more efficient oil/water separation and suspended-solids removal than conventionally cast hydrophilic and oleophilic membranes.
