PES Advantages
PVDF Limitations
PES membranes deliver unmatched water permeability and flux rates through their inherent hydrophilicity, reducing energy costs and increasing throughput in demanding applications like process water purification and wastewater recycling.
Unlike PVDF, which struggles with lower filtration rates for demanding applications, especially in cold water filtration scenarios.
PES systems operate at lower pressure than PVDF equivalents, maximizing filtration flux and cutting operational costs for unbeatable productivity.
With minimal fouling due to its from-inside-out filtration design, PES membranes deliver lower maintenance costs, while providing robust chemical resistance—perfect for harsh industrial environments and long-term value.
Our products
PES hollow fibers
Taike’s latest-generation membrane fiber matches well-known Global brand’s membrane fibers in geometry, selective layer architecture, and support structure, a fact confirmed by SEM analysis.
A modern production line ensures fiber with uniform geometry, eliminating shape distortion and wall thinning.
Polymer concentration in the spinning dope is never reduced: the priority is long-term reliability and service life of the fiber, which is critical for demanding applications.
Taike focuses on precise pore and supporting layer engineering, achieving an optimal balance between permeability, selectivity, and mechanical strength, which makes our ultrafiltration hollow fibers a reliable choice for large-scale drinking water plants.
Competitors often show little distinction between the selective layer and the supporting structure, this leads to increased pressure drop and forces end-user to conduct more frequent and more aggressive membrane cleanings.
Our supporting layer quality is the same like global leader Pentair.
We use premium BASF polyethersulfone rather than generic PES, delivering a higher density of active pores, superior mechanical strength, and consistent performance from batch to batch.
The true pore size of 20 nm on the selective surface of our membranes, combined with the absence of macro-voids, ensures outstanding filtration quality and highly stable barrier properties.
By contrast, many competitors operate with a pore size range of 20 - 100 nm (still formally classified as ultrafiltration), increasing average pore size to cut costs and boost permeability at the expense of filtration quality and reliability.
Our quality is at the same level as global leading brands like Pentair.
