Ultrafiltration

Ultrafiltration

Many impurities in the water are not visible to the human eye. Therefore, our DOW™ ultrafiltration is based on a PVDF membrane with a separation limit of 0.03 µm (100 kDa). Thus even the smallest algae, bacteria or viruses are caught.
Ultrafiltration is a filtration process from the field of membrane technology, with which macromolecular substances and small particles can be separated from a medium and concentrated. Ultrafiltration is used for pretreatment and direct filtration of liquid media. It can, for example, separate particulate matter as well as bacteria and viruses.

Ultrafiltration is used among other things for


The IntegraPac™ modular system offers a scalable solution for your ultrafiltration rack from 306m² to 1,694m² membrane area per rack.

PolyCera®

PolyCera CMYK Logo2

Robust, easy to clean PolyCera membranes extend the range of ultrafiltration and nanofiltration performance beyond conventional ceramic and polymeric membranes.

PolyCera® is a new polymeric material, supplying ceramic like robustness with the flexibility of a polymeric membrane.
PolyCera membranes offer a unique combination of extreme hydrophilicity, permeability and robustness.
PolyCera membranes were developed to extend the range of polymeric membrane filtration to tackle the most challenging applications, delivering stable performance even under extreme pH, temperature, fouling and chemical conditions. This means low energy and high sustainable flux operation with extended membrane life, maximum system uptime, and minimal residual waste to manage.
PolyCera membranes are designed as spiral wound elements in configuration of 1,8“, 4“ and 8“. They are available as ultrafiltration (10 kDa, 70 kDa, 100 kDa, 250 kDa and 500 kDa) and nanofiltration (500 Da).
The use of feedspacer up to 120 mil offers a wide range of applications even with very high solids. The PolyCera elements are 100% backwashable.
The elements can be operated in vertical and horizontal mode and fit into standard RO pressure vessels.

DOW™ Ultrafiltration

The DOW™ ultrafiltration is based on a PVDF membrane with a separation limit of 0.03 µm (100 kDa). What is special is the filtration mode from the outside to the inside. The membrane is highly resistant to chemicals, very easy to clean and has low operating costs. It is used for preliminary filtration upstream of reverse osmosis systems, drinking water treatment and waste water treatment. The SFP/ SFD module series  has been in operation for many years and has a large number of references worldwide. The modular module system IntegraPac™ offers a scalable solution for your ultrafiltration rack. Thanks to the intelligent design of the end caps, which simultaneously serve as collectors, the rack can be set up in the smallest of spaces. The system is variable and can be adapted to the requirements. The new IntegraFlo™ module design features a membrane area of up to 102 m². And this with a diameter of 219 mm (8") and a length of 2,359 mm (80"). This module covers the need for cost optimization in water and waste water treatment plants.
