Consistent, Superior Filtrate Quality

EuroTec UF membrane is consistently able to provide high quality filtrate output in spite of the wide fluctuations in feed water quality. As an absolute barrier, anything larger than the rated pore size (which includes suspended solids and microorganisms) will be retained, regardless of the type of constituents in the feed water. This gives assurance to users and operators that only filtrate output of low turbidity and virtually non-existent microorganisms are provided for direct usage or further downstream treatment.

Excellent Chemical Stability and Resistance

The EuroTec UF membrane base chemistry is a modified quality of Polyvinylidene fluoride (PVDF) material, which inherently has higher chemical resistance – especially in terms of oxidizer tolerance as well as being able to operate within an extremely wide pH range (1 – 13).

This has a direct positive impact on membrane lifetime as higher chemical resistance translates to slower rates of wear-and-tear, of which can be largely attributed to the frequency of chemical cleaning cycles and the membrane surface direct contact with chemical agents in the feed water.

Outside-In Flow Mode

The EuroTec UF hollow fibre membrane is of outside-in flow configuration, which in comparison to inside-out flow membrane, allows for higher fouling tolerance as well as more effective removal of foulants from the surface via a combination of backwash and air scouring.

The outside-in flow membrane is more versatile in regards to the type and quality of feed water it can accept. Also, it typically requires less pre-treatment such as coagulation and flocculation.

Narrow Pore Size Distribution

High porosity is only desirable when pore size distribution, i.e. the size differences between each individual pore, is well-controlled. If pore sizes vary too much, the large pores tend to be fouled quickly leading to a rapid drop in permeability.

With EuroTec unique fibre spinning technology, our UF membrane is able to achieve an extremely narrow pore size distribution. The pore sizes at the surface of the membrane are consistently of 0.025 micron diameter with very minimal deviation.

The result of this is an enhancement of the membrane’s anti-fouling capability and better filtrate water quality.

High Porosity Single-Skin Membrane Layer

The surface of the EuroTec UF membrane is essentially a highly porous, hydrophilic filtration layer. In addition, the fibre is designed to be single-skinned where the filtration occurs only at the surface and the rest of the membrane is the porous supporting layer. Each fibre is also of asymmetric structure.

Consequently, all these factors collectively allow for higher permeability and the achievement of higher flux rates.

High Strength and Durability

The EuroTec UF membrane hollow fibres are designed to have a sponge-like structure without the presence of macrovoids to compromise its structural integrity.

This is achieved using a TIPS/VNIPS fibre spinning method

The result is a high strength, high durability membrane with very minimal fiber breakages that is able to deliver a long service life with low maintenance requirements.
