Multibore® Membranes


Our Multibore® membrane combines seven individual capillaries in a highly robust fiber. The capillaries have an internal diameter of 0.9 mm or 1.5 mm. The water to be treated is forced through the capillaries and disperses laterally through the pores of the membrane, which are just 20 nanometers in diameter. Suspended solids, viruses, germs and bacteria are retained inside the capillaries. Thanks to the honeycomb-style arrangement of the capillaries, the stability of the membrane is extremely high. In contrast to conventional single-fiber capillary membrane products – which are prone to sudden breakage – our Multibore® membrane is so stable and resilient that not a single fiber breakage has occurred since we put it into operation in the first ultrafiltration plants. Our technology is therefore the optimum choice for maximum operating reliability.


Two membrane sizes for different raw water types

Our Multibore® membrane delivers a consistently high level of filtrate quality, even in cases where the composition of the original water varies. The decision of whether to choose a Multibore® membrane with a capillary diameter of 0.9 mm or 1.5 mm depends on the concentration of solids in the raw water.

 Our inge® team of experts will be happy to assist you in making the right choice.
