Multibore tubular ultrafiltration membranes available in two series: C-Series (ceramic — maximum durability and chemical/thermal resistance) and P-Series (polymeric — high performance with better cost-effectiveness). The ideal solution for each quality, capacity, and operating condition requirement.
MultiBore technology was developed to overcome the limitations of conventional single-channel tubular membranes. Each module contains multiple parallel channels (7 channels per membrane in the standard geometry), which better distribute mechanical forces and significantly increase structural robustness — eliminating the main failure mechanism of conventional hollow-fiber membranes: pressure-induced rupture.
The multibore geometry also maximizes filtration area per module and allows high-intensity backwash flows without collapse risk, ensuring greater longevity and operational reliability. Available in two series to serve everything from municipal wastewater treatment to highly chemically and thermally aggressive industrial applications.
7 parallel channels distribute mechanical forces and eliminate membrane collapse risk during backwashing.
0.02–0.04 μm pores retain 100% of solids, bacteria, viruses, and protozoa — regardless of load variations.
Scalable modules in external racks or integrated with MBR systems — adaptable to any capacity.
Pressurized effluent enters through the tubular channels of MultiBore modules. Transmembrane pressure (TMP) forces liquid through the UF pores, retaining all solids, colloids, bacteria, and protozoa in the lumen. Permeate collected externally is directed to subsequent steps.
Membrane cleaning is performed through regular backwash cycles (reverse permeate flow) and relaxation (filtration pause with aeration), plus periodic chemical cleanings (CIP) with acid or alkali based on identified fouling. The multibore geometry withstands high backwash flows without membrane damage risk, ensuring complete flux recovery.
Effluent enters tubular channels; permeate collected externally after passing through UF pores.
Reverse permeate flow removes fouling — multibore geometry withstands high intensity without damage.
Programmable chemical cleaning restores original membrane flux, maintaining projected service life.
